Utility Statistics for Calendar Year 2004 ii EXECUTIVE SUMMARY TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT MAY 2005 INTRODUCTION In October, 1996 the Oro Valley Town Council (Mayor and Council) formed the Oro Valley Water Utility Commission (Commission) to act as the official advisory body to the Mayor and Council regarding water related issues. The functions and duties of the seven member commission include reviewing and developing recommendations for water revenue requirements, water rate and fee structures, and water system capital improvement planning. The Commission is required to prepare an annual report to the Mayor and Council regarding its recommendations. This report is the Commission's eighth Annual Report. It includes recommendations related to water conservation, revenue requirements, system operation and maintenance, debt service, a five-year capital improvements plan, rate adjustments and renewable water supplies. The Executive Summary contains a briefing on the implementation of the recommendations presented in the 2004 Annual Report as well as new recommendations specific to water issues facing the Town in FY 2005-2006 and beyond. Explanations and financial analyses that are more detailed may be found in the report and the appendices. WATER RATES, FEES & CHARGES The potable water rates recommended by the Commission last year were adopted by Mayor and Council in June 2004. Implementation of those rates provided a 3% revenue increase. The increase was achieved by increasing both the monthly base rates and the commodity rates. The reclaimed water rates were also increased and remain equal to the potable water base rates and the tier 1 commodity rate. A discounted rate for using reclaimed water was not considered since the utility did not have reclaimed customers at that time. Additionally, the Mayor and Council adopted increased fees for reconnection of water service, revised the new development construction inspection fees, and established new development plan revision fees along with document reproduction fees. With regard to the recommended rates and fees for the upcoming fiscal year, the Commission's preferred financial scenario is discussed in detail in the report. Concerns regarding the applicability of the current rate setting criteria have been brought to the attention of the Commission. As a result, the Commission has provided a recommendation of no rate increase for FY 2005-2006 to provide additional time to review, evaluate, and possibly modify the rate setting criteria for submittal to the Town Council for formal adoption. CONSERVATION The water conservation program is proving to be a viable asset in assisting the utility to achieve its overall management goals. The conservation program, becoming more commonly known as I CARE, utilizes a broad approach embracing five major concepts: Incentives, Consultations, Audits, Research and Education. The utility has received significant feedback from residents on articles that have appeared in the Oro Valley Water Ways indicating the success of the newsletter. The audit program has been well received and residential interest appears to be growing steadily. Audits, along with the newsletter have become valuable tools for public education. The utility has broadened its area of water management consultations to include interdepartmental services for irrigation and landscape design review, education and implementation of new technologies, new water management strategies, staff training, pilot projects and code modifications. The utility continues to aggressively promote water conservation through public speaking engagements with civic organizations, the Citizens Planning Institute and local newspaper articles. Specifics on all aspects of the conservation program are discussed in the report. As the conservation program evolves and grows, the Commission recognizes that existing staff dedicated to the conservation program will be unable to meet the demands placed on him. The upcoming projects critical to the success of the overall conservation program will be labor intensive and more than one person can effectively perform. Therefore, the Commission is recommending the addition of one full time employee to sustain existing water conservation programs and facilitate improvement of the overall program. The Town currently has a CAP water allocation of 6,748 acre feet per year and is anticipating the acquisition of an additional allocation of 3,557 acre feet per year. The necessary vehicle for conveyance of CAP water to the Town does not exist making direct use of this resource impossible at this time; however, the Town has been cooperating with other local water providers and the Bureau of Reclamation to develop a regional CAP delivery system within the northwest Tucson area. Based on conceptual plans that have been developed, the cost for the system is estimated to be $180 million. These costs would be shared by all participants and the federal government. The extended drought conditions have resulted in declining volumes in the Colorado River reservoirs. This is a major concern for the entire southwestern United States as well as the -2- n Town. An even larger concern for Arizona is that the CAP water system holds a junior right among the seven basin states. During a water shortage, the CAP water system would have to completely cease using Colorado River water prior to any of the other right holders having to reduce their usage. The Town has partnered with other local water providers on a managed recharge facility within the Santa Cruz River channel. Along with the others, Oro Valley has legal ownership to a portion of the effluent discharged into the Santa Cruz River and will accrue long term recharge credits that can be used to offset future Assured Water Supply requirements or the water can be recovered to supplement the Town's reclaimed water system. RECLAIMED WATER SYSTEM Approximately eight years ago, an alternative water resource task force was assembled to evaluate all potential options to bring renewable water resources to the Town. In 2000, after much studying and evaluating, it was determined that the most cost effective and quickest solution would be to bring reclaimed water into the Town and use it for turf irrigation. The Reclaimed Water System Master Plan was adopted in 2002, bonds were sold in December 2003 and construction began in April 2004. At long last, Phase 1 of the reclaimed water system is expected to begin delivery to the three golf courses north of Tangerine Road in July 2005. This system will be a significant benefit to the potable water supply and the community as a whole. WATER QUALITY For the third consecutive year, the utility is proud to report that it did not experience any water quality violations for Total Coliform bacteria. Considering the volume of samples taken, the number of people involved in the process and the ease with which contamination of a sample can occur, the fact that no water quality violations occurred should be considered remarkable. Of the hundreds of other water quality samples tested annually, no contaminant was found to exceed the Maximum Contaminant Level. WATER SUPPLY Continuation of the drought and pumping of groundwater have caused groundwater levels to finther decline, which in turn reduced the production capability of the existing system. As a result, the utility had to make modifications to existing wells in order to get the maximum amount of water from each facility. Four of the older wells were taken out of service altogether because the cost to rehabilitate them far out weighed their potential production capability. Implementation of the reclaimed system will definitely help the potable water supply, but it is not the only resolution to sustained reliability. The utility will need to take an aggressive -3- approach to drilling new production wells to replace lost capacity. In particular, for FY 2005-2006 the utility has identified a hydrology study that would incorporate a series of exploratory borings deep into the aquifer to help identify areas more suited for long term groundwater pumping. SECURITY The utility has begun mitigation of security issues identified in the Vulnerability Assessment that was submitted to the Environmental Protection Agency in June 2004. Improvements specifically for security issues include intrusion detection at water facilities, fire hydrant locking devices, fencing of wellhead equipment within each site and training for all water utility staff. The utility continues to stay abreast of local, regional and national security issues by way of weekly situation reports generated by the federal government. CONCLUSION The Oro Valley Water Utility Commission is proud to serve the Mayor and Council and citizens of the Town of Oro Valley. We are pleased to present our Annual Report to the Mayor and Council for their consideration. While much has been accomplished in the past year, the Commission looks forward to direction regarding those items detailed in the Report. We thank the Mayor and Council for their consideration, direction and guidance. !E TOWN OF ORO VALLEY WATER UTILITY COMMISSION ANNUAL REPORT MAY 2005 The functions and duties of the Oro Valley Water Utility Commission include reviewing and developing recommendations for water revenue requirements, water rate and fee structures, water conservation, renewable water supplies and public information and education. In evaluating staff recommendations regarding the water rates and fee structure, the Commission examines the following conditions: the financial scenario must meet Town policies; the operating costs have been reviewed and determined to be appropriate; and proposed rate increases are kept to a minimum. The Annual Report is the means by which this information is presented to the Town Council for their consideration. Any recommendation that requires action by the Town Council will be presented for their approval at a later date. Additionally, the Annual Report discusses projects the Commission has been involved with during the past year and provides a work plan for the upcoming fiscal year. PREFERRED FINANCIAL SCENARIO As done in the past, the Commission's finance subcommittee evaluated numerous financial scenarios prior to forwarding a recommendation to the Commission. Their initial recommendation indicated 3% annual rate increases and no discount for using reclaimed water. This recommendation was formulated based on the rate setting criteria that has been in place since 1998. Prior to the Commission formally voting on the preferred scenario, Town staff introduced new information for their consideration. This information included a reduction in anticipated annual growth from 500 to 440 connections, deferring approximately $2.3 million in capital projects until FY 2006-2007, a combined beginning cash balance of approximately $18 million, concern that the impact of the reclaimed water system will be unknown until it has been operational for a period of time, and the applicability of the existing rate setting criteria given the date it originated and the fact that it has not been formally adopted by the Town Council. The finance subcommittee reviewed three additional scenarios with reduced growth factors and deferred capital projects. Deferring the capital projects had no impact on the proposed water rates since they are financed by bond funds; however, the deferment resulted in a larger cash balance at the end of FY 2005-2006. The reduction in the annual growth projections had a significant impact on the proposed water rates. Although the utility has averaged 500 new connections over the past three years, the growth factor was reduced to conform to a Town survey of the development community. Once the revised growth factor was substituted in the financial projections, the original preferred scenario no longer met all the existing rate setting criteria nor did the remaining two scenarios. -5- Based on the results of the last three scenarios, coupled with concerns about the applicability of the rate setting criteria and the unknown impacts of the reclaimed water system, the finance subcommittee formulated a new recommendation on water rates. Their recommendation to the Commission was no rate increase in FY 2005-2006, no discount for reclaimed water use, and to re-evaluate the existing rate setting criteria. The finance subcommittee also recommended that an alternate financial scenario that met the existing criteria be presented to the Town Council. The Commission is forwarding these recommendations to the Council via this report. However, the recommendation for no rate increase is delivered with a caveat: should any circumstance arise that could be financially detrimental to the utility, the Commission will revisit the rates at that time. Furthermore, the Commission is proposing to re-evaluate the existing rate setting criteria as well as other potential criteria and take their findings to the Town Council in a joint study session prior to seeking Council adoption of all rate setting criteria and/or policies. With regard to the Preferred Financial Scenario, the following are some of the assumptions used to develop the financial projections: ➢ Projected expenditures are adjusted for inflation, O&M expenses, debt service and water system improvements. ➢ Golf courses are expected to be removed from groundwater over a period of years commencing in FY 2005-2006. ➢ Revenue projections include a residential customer growth factor of 440 residential units per year over the five year period. This estimate is based on the results of a survey performed by the Town. ➢ All sources of water revenue will be used to repay debt and include: water sales, groundwater preservation fees, reclaimed water sales, potable and alternative water impact fees. ➢ New debt will be issued in FY 2006-2007 to finance potable water system improvements and Phase 2 of the reclaimed water system. Data for the five year projections assumes that both personnel and related costs will incur inflationary increases as well as the addition of personnel. The O&M costs are assumed to increase annually through FY 2009-2010 based on inflation factors received from the Economic & Business Research Center, Eller College of Management at the University of Arizona. Analysis of the Preferred Financial Scenario indicates that it does not meet established financial criteria; however, the Commission will be re-evaluating the criteria as stated earlier. Retained earnings maintain a positive value but the utility experiences a loss for four consecutive years. Additionally, the net revenues provide debt service coverage in excess of 1.30 times the annual debt service as required by the bond covenants and depreciation is fully SZ recovered by the rates. The total cash reserves are maintained in excess of 5% of the projected budget in each year. 1 The projected Income Statement, Debt Service Statement and Cash Flow Statement for the Preferred Financial Scenario may be found in Appendix A. ALTERNATE FINANCIAL SCENARIO The Commission is providing an alternate financial scenario to the Town Council for their consideration. This scenario illustrates the revenue increases necessary to meet the existing financial criteria. In order for the utility to not experience a net loss for more than two consecutive years, the potable water rates would need to be increased by 3% in FY 2005- 2006 and then increased by 4% annually over the next four years. For FY 2005-2006 that would mean a 980 increase per month for the average residential customer. This scenario also provides no discounted rate for the use of reclaimed water. The projected Income Statement, Debt Service Statement, Cash Flow Statement, Rate Schedules and tables showing financial impact to customers may be found in Appendix B. RECOMMENDATION ON WATER RATES, FEES & CHARGES As discussed previously in the report, the Commission is recommending no increase in the potable water rates. It is further recommended that the reclaimed water rates continue to be equal to the potable water rates until there is sufficient operating data to determine what financial impact would be experienced by offering a discount for using reclaimed water. Appendix C contains the existing water rate schedules and tables that reflect customers' monthly bills. Monthly bill amounts are calculated in 1,000 gallon increments for the 5/8" x 3/4" meters and a variety of increments for larger meter sizes. Staff is requesting that the existing Backflow Installation Permit Fee be increased to allow the utility to recover its costs. The fee was initially established in 1999 and should be adjusted to account for increased labor costs. Additionally, staff is requesting that an hourly rate be established for the relocation of hydrant meters and the related backflow assemblies. With fire hydrant security being addressed with the use of hydrant defenders, it is necessary for the utility staff to move these meters at the request of the contractors. The Commission supports both of these fees. Details of each may be found in Appendix D. No other adjustments to service fees and charges are necessary at this time; however, the Commission recommends that the service fees and charges continue to be reviewed on an annual basis. -7- REVENUE REQUIREMENTS The Commission and Town staff analyzed the revenue and cash flow requirements necessary for operation and maintenance, capital improvements and debt service for both the potable and reclaimed water systems. Revenues and cash flows were projected for FY 2005-2006 based on anticipated annual growth in the customer base of 440 residential customers and water consumption patterns similar to calendar year (CY) 2004. Projected operating expenses were developed by the water utility staff. Capital expenditures were identified in the Potable Water System Master Plan, the Reclaimed Water System Master Plan as well as utility staff. Projects will be financed with cash on hand and bond funds repaid with all sources of water revenue. The following table indicates the amount of water sales revenue that would be realized with no rate increase but additional service connections of 440: FY 2004-2005 Revenue Estimate FY 2005-2006 Revenue Projection Dollar Increase $9,222,310 $9,306,967 $84,657 Although all sources of water revenue will be used to repay outstanding debt, revenue received from groundwater preservation fees, potable water and alternative water impact fees will be monitored to ensure that sufficient revenue is collected from each source to pay for capital improvements and/or the related debt service identified as being funded by the respective sources. O & M AND DEBT SERVICE REQUIREMENTS Because of the timing of the preparation of this report relative to the Town's budgeting process, the Commission recognizes that both the projected revenues and the projected expenses may need to be revised. The amounts shown below and used in the financial analysis may differ from those included in the Department Budget Request and the Manager's Budget Review because of the availability of more recent and reliable information. The Commission understands that Oro Valley Water Utility (OVWU) staff, the Town Manager and the Mayor and Council will adjust expenses to fit the final estimate of revenues based on the action of the Council on the rate structure for FY 2005-2006. Personnel costs include the addition of 1 full time employee and 1 part time employee, both of which would assist the conservation staff. Personnel costs also include the reclassification of utility employees based on the Town's recent changes to the Compensation Plan along with annual merit and COLA increases. The request for operations and maintenance costs reflect, among other items, the O&M costs for the reclaimed water system which is anticipated to begin deliveries in July 2005. The J J J -8- J cost to recharge CAP water and the excess groundwater withdrawal fees have also increased; however, these costs are fixed by outside agencies over which the Town has no control. All other O&M costs were projected to have inflationary increases of 3.9% in FY 2005-2006. Inflation factors were provided by the Economic and Business Research Center, Eller College of Management, at the University of Arizona. Principal and interest payments reflect debt service pursuant to repayment schedules for the bonds related to acquisition of the utility; assuming management of the OVWID#1; the bond issue in 2001 for existing system improvements; re -financing the 2000 bonds for system expansion improvements; re -financing the City of Tucson debt; and the 2003 bonds sold for potable water system capital improvements and construction of the first phase of the reclaimed water system. The increase in depreciation is due to the completion of approximately $15,000,000 in infrastructure during the past year. The additional plant consists of Town projects that include water mains, wells, boosters, vehicles, and the reclaimed system along with facilities contributed to the Town by developers via line extension agreements. Since this new infrastructure has been put into service, it must now be depreciated over the expected life of each facility. The following table is a comparative summary of expenses and debt service requirements for the water utility enterprise fund. Budgeted amounts for FY 2004-2005 are compared to the projected expenses for FY 2005-2006 used in the financial analysis: OVWU Expenses FY 2004-2005 Budget FY 2005-2006 Projected Change Increase(Decrease Personnel $ 1,700,436 $ 1,816,753 $ 116,317 $ 2,309,476 $ 2,399,546 $ 90,070 _O&M C.A.P. $ 363,944 $ 363,944 $ 0 C.A.G.R.D. $ 338,200 $ 471,858 $ 133,658 Reclaimed O&M $ 0 $ 630,658 $ 630,658 De rec. & Amort. $ 1,955,173 $ 2,364,746 $ 409,573 Interest Payments $ 2,950,444 $ 2,888,225 ($ 62,219 Payments $ 1,474,750 $ 2,291,880 $ 817,130 -Principal Totals $11,092,423 $13,227,610 $ 2,135,187 CAPITAL IMPROVEMENTS Potable Water System: This past year, the utility has been actively designing and constructing new water system capital improvements for both the existing system and expansion related projects. By June 2005 it is anticipated newly completed projects totaling more than $4 million will be providing service to our customers in the form of increased capacity and system reliability. M 1 Capital improvement projects for FY 2005-2006 include one new well; the rehabilitation of two existing wells; a new 500,000-gallon reservoir; improvements to an existing booster station; completion of a new dual zone booster station; assorted valve replacements and over five miles of new transmission mains. The cost for these improvements is estimated to be $7.4 million. During FY 2005-2006 the utility will conduct a well field capacity assessment for a 10-year planning horizon. The assessment will project annual capacity declines for the main well field from 2004 through 2013. The Groundwater Action Plan (GAP) and the Potable Water System Master Plan (PWSMP) assumed annual capacity loss of 250 gallons per minute. In the past couple of years, drought conditions coupled with increased demands have resulted in capacity losses almost twice as much as anticipated. Additionally, hydrogeologic cross - sections through the central water service area showing current conditions will provide valuable visual aids in assessing changes affecting well capacities. The cross -sections will also facilitate the sighting of deep exploratory borings used to evaluate production potential of deeper layers of the aquifer. Reclaimed Water System: During the past year, the utility has been aggressively constructing Phase 1 of the reclaimed water system. To date, ten of the eleven miles of pipeline have been installed and completion of the remaining pipeline is anticipated in May 2005. The Town's reclaimed water booster station and reservoir are approximately 75% complete with final completion expected by July 1, 2005. Additionally, retrofitting of lake discharge metering stations for the Sun City, Stone Canyon and Vistoso Highlands golf courses and construction of Tucson Water's booster station located on Thornydale Road are scheduled to be completed by June 1, 2005. This booster station will pump reclaimed water from Tucson's reclaimed facilities to the Town's reclaimed reservoir. Tucson's permanent "in -line" booster will not be completed prior to July as a result of their difficulties acquiring land from Pima County. This facility is important to the Town's reclaimed system because it will ensure the utility will have enough capacity to deliver the demands of all three northern golf courses as well as the ability to meet the capacity requirements of Phase 2. As a result, Tucson has agreed to construct a temporary booster in the right-of-way which is anticipated to be completed before July 2005. Completion of the Phase 1 components as described above will reduce the Town's dependence on groundwater for irrigation purposes. Using reclaimed water to irrigate the three northern golf courses will save an estimated average of 1.3 million gallons of potable water every day. The final cost of Phase 1, including design, is projected to be $14,000,000. In May 2005, the utility will begin to develop a scope of work for the design of Phase 2 of the reclaimed water system. Phase 2 facilities will deliver reclaimed water south of Tangerine Road to the two 18-hole El Conquistador golf courses, Riverfront Park on Lambert Lane and the Naranja Town Site. It is anticipated that construction of Phase 2 would be done during FY 2006-2007 with reclaimed deliveries to begin in July 2007. The cost of Phase 2 10- facilities, including design engineering, is estimated to be $9,150,000. The utility has planned for bonds to be sold in CY 2006 to finance the facilities. Capital projects will be funded with cash on hand and bond proceeds repaid with all sources of water revenue. Details of the capital improvement program may be found in Appendix E; however, the following table summarizes the utility's five year CIP: Oro Valley Water Utility Five Year Capital Improvement Program 5 Year C.I.P.

Despite increases in new service connections and the severe drought conditions that persist in this region, no water restrictions were imposed in 2004. This is a heartening indication that there may be a heightened awareness of the importance of conservation. In addition, the program has broadened its focus. The utility has become involved with other Town departments in re -thinking parking lot and drainage designs to reduce potable usage in their landscape. The Conservation Specialist is active in development reviews and plans examinations, recommending equipment alternatives for Town facilities and new buildings. The Commission's vision includes identifying potential sites for enhancing recharge and partnering with community members to utilize new technologies and management methodologies. The utility is also involved in research with professionals in the water industry to find practical solutions to water management issues. The utility continues to exceed the goals prescribed in the ADWR Third Management Plan and has become an example for others in the region to follow. The Town is conserving water to insure the future of Oro Valley. The conservation program follows a broad approach that embraces five major concepts which include: INCENTIVES CONSULTATIONS AUDITS RESEARCH EDUCATION - 11 - INCENTIVES The rain sensor program is currently the only formal incentive program available. To date jover 600 units have been sold and customer interest continues to be steady. Informally, the utility has what is termed as "implied incentives" consisting of permit fee waivers from other departments for alternative water source installations such as rain water harvesting and gray water installations along with a one time "free" filling of cisterns for customers who install a rain water harvesting system. CONSULTATIONS Water conservation actively contributes input on water management issues with all Town departments. The Conservation Specialist assists in CIP recommendations, converses with staff on alternatives to current management methodologies as well as offering suggestions for utilizing new water efficient equipment. The Conservation Specialist readily contributes expertise on water management issues to homeowner associations, developers, golf courses and residential landscape projects. Staff offers help on interior household water management as well. AUDITS Audits, for both commercial and residential water systems, continue to be the most active element of the conservation program. For residential users, audits offer informal one-on-one question and answer sessions between the property owner and the Town's water conservation representative. This allows the utility to gather data on Oro Valley's residential water usage trends, the type and efficiency of equipment being used in the landscape, and to gain insight into difficulties confronting the user. The Conservation Specialist is able to assess and make recommendations to the homeowner on how to improve their water management and to suggest changes to increase water efficiency in the home and in the landscape. Audits for commercial properties, including homeowner associations, involve assessments of usage trends and irrigation equipment to identify where significant losses are occurring. Staff also consults with their individual landscape service providers to discuss using best management practices for the property. From the inception of this program in 2003, the utility has completed over 300 residential and 15 commercial audits. Additionally, water efficiency audits on Town parks are 80% complete. As a result of the increased demand for audits, staff found it necessary for the utility to engage the services of an independent contractor. Partnerships with manufacturers, organizations and professionals in the water management industry continue to be an ongoing enterprise of the water conservation program. Currently the utility tests new apparatus and equipment developed for use in landscape irrigation as well as cooperates by providing data for research studies being done by others in the field. Modern methods of management are shared and studied as to their viability for use in the Town. Viable and practical technologies and methodologies are then passed on to our -12- J J 1 customers through education channels, audits, consultations and any other means that may be helpful to incorporate those methods into the mainstream of Oro Valley. In addition, the utility has proposed and implemented Town -specific research projects. One such proposed project is the Big Wash Multi -use Pilot Project. Staff hopes to prove the feasibility of in -channel water detention. The project will help determine if stormwater detained in the wash will enhance recharge as well as mitigate peak water flows during a rain event. A more detailed overview of this project may be found in Appendix F. The Town Hall landscape renovation project offers not only a practical example of the beauty and functionality of desert landscape plantings, but also offers potential alternatives to conventional drip irrigation methods. It is generally recognized that a drip system will use from 25% to 40% more water than conventional irrigation systems. This is largely due to poor design, lack of operational skill and poor equipment maintenance. For residential applications in the Town, these concerns may be difficult for many of our customers to overcome. For that reason, the Town Hall project offers two distinct alternative irrigation methods that circumvent those issues with out sacrificing conservation. The data generated from this project will be used in a presentation at a future Irrigation Association conference. EDUCATION Educational efforts by the Town have grown dramatically. Staff continues to publish the bi- monthly newsletter as well as maintain literature displays at both the Town library and utility office. Other important elements of education are public speaking engagements and classes offered by the Town. The frequency of these engagements has grown in relation to the success of the water conservation program itself. The Water Conservation Specialist has made presentations to service organizations, such as local Rotary, Optimists, Kiwanis and Civitan clubs; the Southern Arizona Homebuilders Association; local homeowners associations and individual departments within the Town. The Conservation Specialist has made presentations on conservation to the Town Council and the Citizens Planning Institute and continues to educate customers on water management as part of rain sensor classes. The utility continues its involvement with professional organizations in its efforts to remain current in staff training and expertise. The utility maintains memberships with the American Water Works Association, the Irrigation Association, American Rainwater Catchments Systems Association, and the Water Conservation Alliance of Southern Arizona. There are projects still in the development stage that are designed to widen educational opportunities for customers and broaden the water management skills of landscape service providers. The design phase of the Oro Valley Community Display Garden is nearing completion and is anticipated to be ready for funding and construction during 2005. The Display Garden will be multi -functional in that visitors may use the facility for the educational opportunities offered, it may be rented for private functions, or to just relax and take in the beauty. The Display Garden will offer interactive displays of various methods of water conservation as well as displays of native Sonoran Desert vegetation and other desert J adaptable plantings. A more in depth description of the Oro Valley Community Display Garden may be viewed in Appendix F. J -13- J 1 Another project still under development involves offering classes to residents that deal strictly with specifics of the maintenance, operation, and management of drip irrigation systems. Additionally, the utility would like to offer a Town -generated certification course for landscape/irrigation service providers. The course would offer more specialized and technical information for professionals and would also address Town Codes and ordinances. In addition to these utility generated facets, the Water Conservation Program is experiencing expanded interest by groups and organizations outside of the Town. Numerous feature articles from area newspapers have sparked increased interest by utility customers, water management professionals and manufacturers. The Conservation Specialist and customer service staff have experienced a dramatic increase in telephone calls and walk-in customers with questions on water conservation. The success of the audit program has been influential in instituting similar programs within the state as well as areas outside our Town. The utility's Water Conservation Specialist has been consulted on issues of water conservation/management and Town programs by professionals and businesses from cities and organizations in Colorado, Oregon, Minnesota, and Texas. He has also been selected to be 1 of 15 Regional Authorized Instructors nationwide for the Irrigation Association and is recognized nationally as an expert in irrigation water management. As a result of this expanding interest and the broadening of the water conservation program, the Commission is recommending several short term goals. Short Term Goals Additional Staff To handle the increasing number of audit requests currently received and to handle future demands, the Commission recommends hiring additional staff. This would facilitate the success and expansion of the current programs as well as permit the existing staff to develop a greater frequency of and access to programs and classes designed to assist customers with their water management concerns. The hiring and utilization of a full time employee dedicated to water conservation has allowed the utility to expand its focus on a meaningful water conservation program. There is much more that needs to be done to achieve stated short term goals as well as to begin working toward long term conservation goals. This year the utility found it necessary to hire an independent contractor to relieve the present conservation specialist of audit duties in order for him to appropriate time to fulfill administrative duties and to work on important development reviews and other priority projects. Upon the hiring of additional staff, the expense for the consultant would be eliminated. In order to maintain the present momentum of the conservation program, to build the program to meet its intended goals, to handle the level of telephone calls and audits in addition to the day-to-day administrative duties required, the addition of one full time water conservation specialist is recommended. Reclassification If an additional Water Conservation Specialist is hired as recommended above, it is then J recommended that the current Water Conservation Specialist's position be reclassified to Water Conservation Program Coordinator to more accurately depict the work that would be J J -14- performed which would include administering and expanding the current programs as well as developing Town -wide programs with other departments, staff and residents. Town -Wide Water Conservation Policy The benefits of water conservation extend well beyond the water utility. In addition to complying with state mandated conservation goals, maintaining a sustainable water supply greatly enhances the Town's ability to encourage economic development as well as residential growth. Developing a Town -Wide Water Conservation Policy would help establish water conservation as paramount to the Town's future. The policy would facilitate cooperation among other divisions and departments as they work with developers and builders insuring conservation issues are at the forefront of conversations. A Town -wide policy would enable more efficient development of equipment specifications, efficiency requirements, code changes and new ordinances. A Town -wide policy could help to broaden funding bases for a variety of and substantially more significant incentive programs than the utility is currently able to offer. A Town -wide policy could provide the conservation program with additional funding sources from other Town departments to help the utility continue its water conservation program. The funding is needed for educational programs, customer assistance programs, conservation incentives and other programs that a successful conservation program embraces in order to foster easier transitions to water use efficiency for Town residents and businesses. The monetary burden to support these programs may become too high for the utility alone. As such, the Town - wide policy would permit a portion of the funding to come from other departments within the Town. A Town -wide policy would also publicly declare the Town's commitment to water conservation and help set an example for citizens to follow. Expanding Customer Base for Reclaimed Water Last year the utility identified potential homeowner association common areas along the pipeline route of the reclaimed water system that could be encouraged to use reclaimed water for their irrigation needs. Staff recommended placing access connections in the transmission main during the course of construction. The utility has been approached by a developer that has expressed interest in using reclaimed water for his project. This specific property may well provide us an access right-of-way to Wilson Elementary School, a large turf user that has also expressed interest in utilizing reclaimed water. The utility has also been approached regarding the conversion of median areas from potable water to reclaimed water. The Town has an opportunity to bring reclaimed water into the public sector as a viable alternative to potable water for landscape irrigation uses other than turf. Expanding the reclaimed customer base would be beneficial in funding the construction and operating expenses of this endeavor. A map of the route along with a list identifying potential customers and their current water usage may be found in Appendix F. Long Term Goals The Commission's work plan for future years will encompass evaluation of code changes J that may include comprehensive specifications on irrigation equipment, installation and J quality control. Water audits are indicating that many of the irrigation systems currently J J J J 15- J J ral installed are problematic. Typically they are installed lacking a sufficient number of valves (zones), or designed and installed with substandard materials and/or construction methods conducive to efficient irrigation practices. Presently only rudimentary standards exist on the installation of irrigation systems and residential backflow prevention devices. The existing building codes on irrigation/landscape installations make only general references to required equipment for installation. Potential changes to the Town Code may include minimum acceptable performance standards for irrigation efficiency; stated requirements for backflow prevention installations and specifications on acceptable irrigation installation practices and equipment. To educate landscape service providers on any code changes and to address other water issues, the Commission will evaluate contractor certification classes sponsored by the Town. Due to the number of seasonal residents and also the number of residents new to southern Arizona, there appears to be a general lack of knowledge on proper landscape watering methods unique to the and southwest. As such, there is high water usage throughout the year with no significant reduction in usage consistent with seasonal changes. The utility has observed that a large number of residents have a general lack of understanding on how to use and maintain their irrigation system properly. To bridge this information gap, the Commission envisions classes in irrigation and plant management targeting the residential end user. The classes would be offered in a series to help residents of Oro Valley become familiar with acceptable gardening practices for the Sonoran Desert region. In addition the classes will assist residents in directing the activities of their landscape service providers to insure the level of water management is consistent during extended absences. As the pressures of growth encroach on the Town's natural terrain, stormwater runoff becomes more of an issue in relation to velocity and natural recharge potential. Areas that normally absorb and retain runoff are being covered with impermeable surfaces such as roads, buildings and parking lots. As stormwater from these surfaces drain into washes, speed and volume of the flows increase thus reducing the amount of natural recharge in the washes. The Big Wash Multi -Use Pilot Project will lay the ground work for enhancing the natural recharge in our washes. Data gained from this project will enable the utility to identify and enhance recharge sites throughout the Town and increase natural recharge capabilities. It is the intent of the Commission to include these short term and long term goals in the work plan for FY 2005-2006 as well as future years. The Commission looks forward to returning to Mayor and Council with specific recommendations regarding proposed programs. RENEWABLE WATER RESOURCES The Town of Oro Valley is located within the Tucson Active Management Area (TAMA), one of five special water management areas within the State of Arizona. As such, the Arizona Department of Water Resources (ADWR) regulates groundwater use throughout the TAMA. In general, ADWR requires water providers to institute conservation programs, accurately measure and report groundwater pumpage, and within growing communities, J i J 16- demonstrate a 100-Year Assured Water Supply (AWS), all aimed at eliminating groundwater ,1 mining within the TAMA by the year 2025. In particular, the AWS provisions require the use of renewable water supplies — directly or indirectly — as a means for bringing groundwater pumpage within the TAMA into balance. This concept is known as "safe yield". The Town of Oro Valley has demonstrated its ability to meet the AWS and is currently designated by ADWR as having an Assured Water Supply. Information regarding the Town's existing and future renewable water resources is located in Appendix G. The Town currently has a legal allocation to CAP water in the amount of 6,748 acre feet per year. In addition to this allocation, the Town anticipates acquiring a portion of the unallocated Municipal and Industrial (M&I) CAP water as part of the reallocation process conducted by the State. ADWR has recommended that the Town of Oro Valley be allocated 3,557 acre feet per year out of approximately 60,000 acre feet per year available through this process. In November of 2004, the U.S. Congress and the President approved the Arizona Water Settlements Act (5.437) that settles several Indian water rights claims in Arizona, defined the repayment obligations of the state for construction of the CAP and authorized the reallocation of unclaimed M&I CAP contracts. The Arizona State Legislature must now act on the Settlement Agreement prior to the final reallocation taking place. Utility staff received an inquiry from the CAP financial offices regarding the timing of payment for the past capital charges on the reallocation of 3,557 acre feet; however, no time frame for finalizing the reallocation was confirmed. Currently, the only CAP water the Town utilizes is for recharge. The Town has been recharging 2,500 acre feet of CAP water per year and has accrued long term storage credits (approximately 14,500 acre feet) that can be used to help meet its AWS requirements in the future. At this point in time, the infrastructure necessary to convey CAP water to the Town does not exist, making direct use impossible. However, the Town has been cooperating with other local water providers and the Bureau of Reclamation to develop a regional CAP delivery system within the northwest Tucson area. To date, a conceptional plan for the direct delivery of CAP water to customers in the northwest area has been developed and various treatment methods have been researched and investigated. In concept, the northwest water providers would construct a turnout for CAP water in the vicinity of Tangerine Road and Interstate 10, a reliability reservoir, a treatment plant and a transmission system capable of treating and delivering approximately 30,000 acre feet per year (24 millions gallons per day) of CAP water into the northwest area. The total cost of this system is estimated to be approximately $180 million which would be split among the four participating water providers and the federal government. Even though this is an extremely complex project and will likely take many years to accomplish, the Town of Oro Valley is committed to the direct use of CAP water and will continue to work with our partners to see that this concept becomes a reality. Another major issue facing the Town, and the entire southwestern United States, is the possibility of water shortages within the Colorado River System. Given the extended drought that has plagued this area for over six years, the reservoirs on the Colorado River (Lake Powell and Lake Mead) are at their lowest levels in decades. Since a shortage J -17- -� declaration on the Colorado River has never been made by the Secretary of State, the "law of the river" — a complex mix of agreements and court decrees that govern the operation and water allocations associated with the Colorado River — does not adequately address how shortages are to be shared among the seven basin states. One big concern for Arizona, and particularly those water providers that rely on CAP water, is the fact that the CAP system holds a junior right among all of the lower basin states. In other words, during a shortage, the CAP system would have to completely cease using Colorado River water prior to any of the other right holders having to reduce their use at all. This is an extremely important issue for Arizona and Oro Valley will be providing what support it can during the coming year to help resolve this issue. In addition to CAP water, wastewater effluent is the only other renewable water resource available to the Town of Oro Valley. Oro Valley's plan to utilize effluent as reclaimed water is addressed later in this report. Over the past three years, Town staff has been working with other water providers and governmental agencies within the region to develop a managed recharge facility within the Santa Cruz River channel to begin receiving recharge credits for effluent discharged into the river. According to State law, those who have ownership of the effluent being discharged into the river may apply to receive long term recharge credits for the water actually recharged. These credits are limited to 50% of the water recharged within the boundaries of the managed recharge facility. The Lower Santa Cruz River Managed Recharge Project is located within Pima County, along a 16-mile stretch of the Santa Cruz River and was fully permitted in November 2003. Under this permit, secondary effluent is discharged to the river from the Roger Road Wastewater Treatment Plant and the Ina Road Wastewater Treatment Plant, where a significant amount of it recharges within the proposed project area. Along with others, Oro Valley has legal ownership to a portion of the effluent discharged into the Santa Cruz River and is interested in accruing long term recharge credits associated with its infiltration. These credits can be utilized in the future to offset AWS requirements or recovered to supplement the Town's reclaimed water system. At the time of this printing, the Town did not have a final accounting of the recharge credits accrued for the 2004. WATER QUALITY The mission of the utility is to provide assurance that drinking water is safe, clean, and meets all local, state, and federal drinking water health standards. In order to protect public health, the United States Environmental Protection Agency (USEPA) sets drinking water standards which all public water providers must meet. Regular monitoring and testing of the water supply is required to assure customers are provided with safe water in their homes and businesses. The USEPA regulations require water providers to regularly test public drinking water supplies for bacteria and other microorganisms, and numerous other natural -occurring or man-made organic and inorganic constituents. MFZ Over the course of a year the utility collects hundreds of water samples from 19 "point of entry" sites including groundwater wells, reservoirs and pumping stations. In addition, the 1 utility also sampled from 38 "sample stations" located throughout the water distribution l system specifically selected to represent the entire water delivery system. Each sample is tested for numerous constituents which may include bacteria, minerals, metals, or man-made chemicals. The USEPA sets national drinking water standards which are administered in Arizona by the Arizona Department of Environmental Quality (ADEQ). The utility provides all water quality testing results to ADEQ and works closely with that agency to ensure all federal and state standards are maintained. It is important to remember that the detection of a contaminant in drinking water does not necessarily represent a threat to public health. Current technology allows water utilities to detect extremely low levels of contaminants in drinking water. Groundwater is the source of all drinking water delivered by the utility. All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. Oro Valley's groundwater contains dissolved minerals and organic compounds, which have been leached from the rock, sediments, and plant materials through which the water traveled. One would expect to find minerals such as calcium, magnesium, chloride, bicarbonate, sulfate, and metals such as iron, copper, arsenic and lead, which may be either beneficial or harmless at low concentrations, but harmfixl at high concentrations. In addition to these naturally occurring contaminants, our groundwater may contain contaminants resulting from human, industrial or domestic activities. For this reason, water utilities must currently monitor for approximately 73 regulated and 13 unregulated contaminants. Other contaminants that may be present in source water are microbial contaminants, such as viruses and bacteria, which may come from sewage, agricultural livestock, and wildlife. Total Coliform is an indicator to more closely monitor the distribution system for possible unwanted bacteria. The utility disinfects its water sources by adding chlorine as a precaution against bacterial growth in its distribution system. During the past three years, the utility has collected 1,368 samples for analysis of Total Colifonn bacteria, none of which resulted in detection. Very few water utilities have experienced this success. Additionally, the utility received a compliance status of "No Major Deficiencies" from the ADEQ for both water systems. Inorganic Compounds (IOC), such as salts and metals, can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. Three inorganic contaminants of special interest are arsenic, fluoride, and nitrate. Fluoride and arsenic are naturally occurring and tend to increase as water is drawn from greater depths. Arsenic is a naturally occurring mineral know to cause cancer in humans. The utility conducted compliance tests for arsenic in it wells in 2004. The J water systems arsenic levels ranged from "no detect" to 1.3 parts per billion (ppb). The EPA J standard for arsenic is now 10 ppb. Fluoride is found naturally in our drinking water. Oro Valley's groundwater has fluoride at low concentrations ranging from 0.15 to 1.0 parts per million (ppm), well below the EPA limit of 4.0 ppm. Fluoride at a level of 1.0 ppm has been J shown to help prevent tooth decay. In substantially greater concentrations, fluoride can be harmful. Nitrate is typically found in higher concentrations near the surface of the J J J -19- J r, n groundwater table because it is frequently associated with fertilizer use, septic tanks and 1 other human activities. Nitrates in drinking water at levels above 10 ppm could pose a health risk for the elderly and can cause blue baby syndrome. The concentrations for nitrates in Oro Valley's water range from 1.0 to 3.6 ppm. Additionally, most lead and copper contamination occurs within the water distribution system or household plumbing and is caused by low pH or corrosive water coming into contact with plumbing materials that contain lead. Lead and copper are regulated by a Treatment Technique that requires water systems to control the corrosiveness of their water. If more than 10% of tap water samples taken exceed the action level, water systems must take additional remediation steps. For copper, the action level is 1.3 ppm and lead is 0.015 ppm. In 2004, fifty water samples were taken within the customers' residences throughout the distribution system. Sampling in 2004 had results for lead as "no detect" and the highest copper level was 0.75 ppm. None of the remaining 3 contaminants in this group have been detected in Oro Valley's water supply. As a result of meeting compliance regulations over several years, the utility is only required to sample every three years instead of annually. Synthetic Organic Compounds (SOC) include pesticides and herbicides which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. The utility has never detected any SOC in its water supply. Due to regulatory changes and increases in Oro Valley's population, monetary cost for the water quality program has continued to rise. The utility continually investigates opportunities to reduce sampling costs while maintaining the safety and health of its customers. In 2003, ADEQ granted the utility a waiver for the constituent Glyphosate. Receipt of this waiver saved the utility approximately $6,500 in laboratory analysis during FY 2004-2005. Glyphosate is an organic solid comprised of odorless white crystals. It is an herbicide used to control broadleaf weeds and grasses and is found in products like Roundup, Sting, and Tumbleweed. The contaminant has never been detected in Oro Valley's water supply and there is no evidence of large scale use within the utility's service area. The utility is also working in concert with other local water providers in southern Arizona to obtain waivers for a number of SOCs that are found in herbicides and pesticides in more agricultural locations. If waivers for SOCs are granted by the State, all water providers would save a significant amount of money in laboratory analysis. hi 2005, the utility will work with Pima Association of Governments (PAG) to initiate the waiver process with ADEQ to reduce the cost of sampling for dioxin and the SOC contaminant group. Volatile Organic Compounds (VOC) includes such compounds as trichloroethylene (TCE) and tetrachloroethylene (PCE). These compounds are volatile like alcohol or gasoline and are made up of relatively small molecules which allow them to migrate readily through soils. Solvents such as TCE and PCE have been commonly used for cleaning machine parts and for dry cleaning. Despite the vulnerability of groundwater to such contamination, none of these contaminants have been detected in Oro Valley's water supply. Total Trihalomethanes (TTHM) are formed when chlorine combines with naturally occurring organic material in water. Since the level or organic matter in our groundwater is extremely low, these compounds are found at very low concentrations. The highest TTHM result in any system sample was 0.0054 ppm. The EPA standard is 0.8 ppm. r� r, n r, - Adjusted Gross Alpha is a measure of radioactivity due to naturally occurring minerals in groundwater. The standard for gross alpha radioactivity is set at 15 picocuries per liter (pCi/1). The range for Oro Valley's water supply is "no detect" to 4.3 pCi/l. During 2004, the federal government promulgated the testing requirement for Radium-228. Four quarters of testing was completed and Radium-228 was not detected. The level of water hardness varies from one well to another. Hardness is a measurement of the concentration of calcium and magnesium in the water. If the hardness of water is more than 120 ppm, then a water softener would probably reduce the formation of scale within a household and make soap lathering easier. Hardness levels above 170 ppm could shorten the life of water using appliances. The hardness levels in Oro Valley's water range from 34 ppm to 80 ppm. The hardness scale is: 0-75 ppm is considered soft water; 75-150 ppm is moderately hard; 150-300 ppm is hard; and more than 300 ppm is very hard water. Every year the water utility distributes an Annual Water Quality Report to all customers. The report contains mandatory language provided by the EPA regarding water quality topics including information on different constituents and their health effects and bottled water and its potential for contaminants. A complete listing of all contaminants that the utility tests for and the most recent test results may be found in Appendix H. The groundwater delivered by the utility meets all drinking water standards without treatment. However, approximately 0.5 ppm of chlorine is added to the drinking water supply at well sites, reservoirs and other facilities to provide assurance that water delivered to customers will remain free of microbiological contamination. Because of chlorine's effectiveness in killing germs, disinfection with chlorine provides critical protection for drinking water consumers. Around the world, millions of people suffer from waterborne diseases due to microorganisms in their drinking water. In the United States, we have few waterborne disease outbreaks because the water is very carefully monitored for disease - causing organisms. Most water providers add a chlorine -based disinfectant to the drinking water supply to kill existing microorganisms. WATER SUPPLY The aquifer beneath the Town of Oro Valley is currently the sole source of water for all uses within the Town. The current state of the aquifer is affected by long-term and short-term groundwater withdrawals and natural recharge. Groundwater withdrawals occur at the active water supply wells owned and operated by the Town and some privately owned wells. Natural recharge occurs from the infiltration of surface runoff near the mountain fronts of the Santa Catalina and Tortolita Mountains and the stream beds of the Big Wash, Canada Del Oro Wash and other smaller washes in the area. Current water demands supplied by withdrawals of local groundwater resources have outpaced groundwater recharge, resulting in a localized groundwater deficit. Over the past several years, dry conditions (drought) have persisted with less than normal precipitation and -21- n runoff. Not only has the drought resulted in less recharge, it has caused a greater demand for water, which further exacerbates the current deficit. As a result, marked water level declines ,-) within the Oro Valley Water Utility service area have been experienced Static groundwater level measurements taken in January of this year indicate an average decline of 5.95 feet for OVWU wells located within its service area. Current system demand coupled with less than average rainfall over the past four or five years is a large contributor to the falling groundwater levels. In fact, it appears that we are currently in the midst of one of the worst droughts Arizona has seen in a very long time. How severe this current drought will be and how long it will last cannot be predicted, but even under normal rainfall conditions it would take many years for the water table to recover to previous levels. Detailed information on the individual wells and their associated water levels may be found in Appendix G. In response to these conditions, the water utility has had to change the way it withdraws water from the ground. Many of the utility's wells have required modification and rehabilitation — lowering of pumps, pump replacement, well casing repairs and cleaning, etc. — to regain some of the lost capacity due to stresses placed upon the aquifer by the prolonged drought. In addition, the utility has had to take four wells out of service during the past year because the cost to rehab these wells far outweighed the benefit of keeping them in service. As a result, the utility has taken an aggressive approach to drilling new production wells to replace lost capacity and to keep up with the growing demand. However, it is becoming increasingly difficult to adequately site new production wells that will not adversely impact existing wells in the area. The proliferation of exempt wells — private wells with a pumping capacity of less than 35 gpm — within the utility's service area, has made the drilling of new production wells increasingly difficult. According to ADWR rules, exempt wells do not have to take the proximity of the utility's production wells into account prior to being drilled; however, the utility does have to consider the impact a new production well may have on an existing exempt well prior to drilling. If it is determined that the new production well may adversely impact the exempt well, the utility must either 1) obtain a waiver from the exempt well owner, 2) reduce the capacity of the production well to such a degree that the impact is mitigated or 3) look for another location. In an attempt to rectify this situation, the Southern Arizona Water Users Association (SAWUA), of which Oro Valley is a member, has proposed legislation that would effectively eliminate the drilling of any new exempt wells within the service area of a water provider that has a designation of Assured Water Supply. SAWUA has made two previous attempts to enact such legislation in the past; however, it appears that passage of an exempt well bill is more likely this session because of widespread support among stakeholders throughout the state. Demand for water in Oro Valley has increased significantly since its incorporation and has more than doubled within the last ten years. Continued growth is expected for Oro Valley at about the same rate experienced during the past several years. Current demand projections .1 'l 1 for the year 2030 — anticipated build -out date of the service area — approach 17,000 acre feet per year. Between now and the year 2030, alternative water resources including effluent and �. CAP water will supplement groundwater resources to meet demands. Appendix G includes figures that illustrate Oro Valley's historic (2000 - 2004) and future (2030) water demands, along with the available renewable water resources at the present time and for the year 2030. In addition to the introduction of renewable water resources, Oro Valley will remain dependent on groundwater for a portion of their water supply well into the future. As such, the utility has been looking at various ways to modify how and where they pump groundwater in an attempt to mitigate any negative impacts on the aquifer. In the coming year, the utility intends to embark on several hydrology studies aimed at addressing this issue. In particular, the utility is considering a study that would incorporate a series of exploratory borings deep into the aquifer to help identify areas more suited for long-term groundwater pumpage. From this information, our hydrologists can better predict the response of the aquifer to various pumpage regimes and ultimately recommend a prudent course of action relative to the location, design and construction of new wells within the utility's service area. SECURITY The Public Health Security and Bioterrorism Preparedness and Response Act was enacted in 2002. This federal mandate required the utility to perform a Vulnerability Assessment (VA) and develop an Emergency Response Plan (ERP) that addresses the vulnerabilities identified by the VA. The VA for the Oro Valley Water Utility and the certification that the ERP was completed was submitted to the EPA and ADEQ in June 2004. The ERP will be reviewed and updated annually to ensure that the most current information is contained therein. The utility has continued to expand the development of and response to elements defined in the VA. Staff, with the assistance of a consultant, conducted a series of in-house seminars to train utility personnel on the implementation of the ERP and emergency procedures. This included activation of the Emergency Operation Center and effectively communicating with the media. The hydrant lock program started late last year is nearing completion. There has been extensive cooperation with the three fire districts serving Oro Valley Water Utility customers as well as with other water providers. It is anticipated that all fire hydrants in the utility's service area will have hydrant locks by the end of this fiscal year. Intrusion detection equipment has been installed at all reservoir sites and is being expanded to the well and booster sites. To date, one third of all facilities have been equipped with intrusion detection equipment. It is anticipated that the remaining sites will be equipped by the end of this fiscal year. All of the utilities production facilities have been declared high security restricted areas. As such, gate locking devices have been enhanced and the appropriate signage has been posted. 23 - The utility is kept abreast of local, regional and national security issues via Water ISAC Weekly Situation Reports. The target date for completion of security measures and/or policies defined in the VA is estimated for FY 2008-2009 at an approximate cost of $800,000. UTILITY OPERATIONS The utility continues to be proactive in the implementation of maintenance programs and facility upgrades. The motor replacement program for wells and booster stations is ahead of schedule and should be completed by the end of FY 2004-2005. Once fully implemented, the utility should realize a reduction in power costs as well as an improved maintenance factor on booster pumps and motors. The development of an overall preventive maintenance program is on -going. Facility sites are in the process of being evaluated so that necessary upgrades can be performed to meet current electrical codes. The SCADA system is in a constant state of improvement to streamline operations and provide critical trending of data. Production facilities staff is responsible for the installation of security devices at the utility's facilities as well as the security program in general. The distribution staff spent the past year identifying all zone boundaries, air release valves and fire hydrants. This information has been organized and entered into a data base to facilitate the preventative maintenance program. Staff is currently in the process of field verifying each water meter that has been installed since inception of the utility. Additionally, the distribution staff has completely equipped their emergency response trailer with assorted repair parts, traffic control devices, lights for night work and a generator. This will provide them the ability to make repairs more efficiently resulting in less service interruption to our customers. With the main replacement for the Oro Valley Country Club area not scheduled to begin until later this year, the distribution staff installed a 2-inch replacement main in an area where water flow through the existing 2-inch main was impeded by tree roots. This provided improved water service to these residents. When the permanent main is installed, the 2-inch main will be abandoned in place. The utility is in the process of implementing a Geographic Information System (GIS) program that will have a significant impact on the water utility. The GIS program is a mapping based tool for efficiently managing local government information. The utility's water system base maps which were created in AutoCAD by a consultant are now being converted to a personal geodatabase and is approximately 45% complete. The conversion and updates to the base maps are done in-house rather than by a consultant. This allows for more timely corrections of missing and/or incorrectly mapped information. J Additionally, the improved analytical capability of GIS technology will also be used to develop the utility's master plan updates. In the future, the utility will be able to collect, store, analyze and combine vast amounts of data needed for hydraulic modeling. Once the J J J J -24- J n n n GIS program is fully implemented, the dependency on outside consultants will be reduced which will result in a significant cost savings to the utility. In an effort to provide increased customer service, the customer service staff participates in an on -going education program provided by other water utility staff. They have attended mini -seminars that include water conservation, meter reading and installation, residential water audits, water elevation zones and the impact they have on water pressure, water quality issues and bluestake protocol. At the request of our customers, the utility recently implemented Water on the Web (WOW) which is the ability to access customer account information on the internet. The information is available through the Town's web site and is updated weekly to provide current billing and payment information as well as a two year history of water usage. Each new water customer receives a packet that includes information on: Water on the Web, billing/payment information, an Automatic Payment (ACH) application, emergency preparation guides, water pressure, the current water quality report, toilet dye test strips, how to locate and read their water meter, how to look for leaks, and a flyer on Pima County Wastewater's frequently asked questions. Utility statistics including new meter installations, customer work orders, and water deliveries for CY 2004 may be found in Appendix I. CONCLUSION The Commission presents this annual report for the review and consideration of the Mayor and Council. The Commission is available to discuss this report in greater detail at a joint study session or other appropriate forum. The Oro Valley Water Utility Commission is proud to serve the Town of Oro Valley and the customers of its water utility. Much has been accomplished in the eighth year of the utility's operation. The Commission extends their appreciation to the Mayor and Council for their consideration and guidance and looks forward to their continued direction on issues discussed in this report. 25 - APPENDIX A PREFERRED FINANCIAL SCENARIO FINANCIAL SCENARIO ASSUMPTIONS Potable Water System: 1.

Inflation factors were provided by the Economic & Business Research Center, Eller College of Management, University of Arizona. 11. CAP costs increase annually for excess water charges to the CAGRD based on water usage and projected fees by the CAP Finance Office. 12. Additional 3,557 AF of CAP water rights acquired in FY 2006-2007. One time expenditure of $1,876,705 has been included in the projections. 13. Continue to recharge 2500 acre feet of CAP water annually. 14. Series 2006 bond issue is planned for spring of 2006. Debt service on the Series 2006 bonds will begin July 1, 2007, but the portion of this issue related to the second phase of the reclaimed system will have interest deferred and capitalized through July 1, 2008. This issue will carry a projected interest rate of 6% and a 25-year term. Semi-annual payments for this portion of the Series 2006 bonds are expected to start January 1, 2009. FINANCIAL SCENARIO ASSUMPTIONS continued: Potable Water System: 15. Potable portion of debt will be repaid with revenue derived from potable water sales and potable water development impact fees. 16. Potable water impact fees remain the same — no proposed increase. 17. Projections do not include any costs for studies or construction of CAP delivery, treatment and/or storage facilities. 18. Depreciation is based on Town standards and is fully recovered by rates. PREFERRED FINANCIAL SCENARIO ASSUMPTIONS Reclaimed Water System: 1. Reclaimed water base rates are equal to potable water rates and the reclaimed commodity rate is equal to Tier 1 of the potable water rate. As a result, when potable water rates are increased, reclaimed water rates will be increased accordingly. No rate increase is proposed for FY 2005-2006; however three percent (3%) rate increases are projected annually for the remaining 4 years. 2. Reclaimed users are assessed the groundwater preservation fee at 210 per 1,000 gallons — no projected increases in the 5 year period. 3. Personnel costs include 2 FTEs over the 10 year period. One hired 3 months prior to Phase 1 deliveries (April 2004) and one hired 3 months prior to Phase 2 deliveries April 2007). 4. Power for pumping is based on $48.13 per acre foot and increases annually by same inflation factors used for the potable system. Reclaimed water costs from Tucson start at $331.86 per acre foot — increases by 3% annually — decreases when more water is taken. (information from Tucson Water) 6. Chemicals for disinfection are based on $5.35 per acre foot pumped and increases annually by same inflation factors used for the potable system. 7. Depreciation is based on Town standards and is fully recovered through rates. 8. Series 2006 bond issue is planned for spring of 2006. Debt service on the Series 2006 bonds will begin July 1, 2007, but the portion of this issue related to the second phase of the reclaimed system will have interest deferred and capitalized through July 1, 2008. This issue will carry a projected interest rate of 6% and a 25-year term. Semi-annual payments for this portion of the Series 2006 bonds are expected to start January 1, 2009. 9. Reclaimed portion of debt will be repaid with reclaimed water sales, groundwater preservation fees and alternative water resource development impact fees. 10. Alternative water resource development impact fees are not expected to increase over 5 year period. 11.

The purpose of the fee is to recover the utility's cost to inspect new backflow assembly installations, maintain a backflow database, notification to owners of testing requirements and following up to insure that the testing was completed and is in compliance with State regulations. The costs to perform duties associated with inspection of new backflow assembly installations and the related follow-up are as shown: Labor 1.5 hours at $23.74 per hour $35.61 Benefits at 30% of gross wage 10.68 Printing of forms, postage, letterhead, envelopes 3.50 Total Costs $49.79 Due to increased labor, printing and postage costs the utility is requesting an increase in the permit fee as shown: Description Current Proposed Backflow Permit Fee $35.00 $50.00 SERVICE FEES & CHARGES Relocation of hydrant meter and backflow assembly: The water utility supplies 3" water meters that are installed on fire hydrants to obtain water used for construction purposes. To insure the safety of the water distribution system, the utility also provides the appropriate backflow assembly. To further protect the water system from potential contamination and water theft, the fire hydrants are now locked with hydrant defenders. When a contractor needs to obtain construction water, utility personnel remove the lock and install the meter and backflow assembly on the fire hydrant. Contractors frequently request that the location of their meter be moved to a different area as their project progresses. Each time the meter/backflow assembly is moved, the backflow assembly must be tested to make sure it is still functioning properly. Labor costs include the relocation of the meter and backflow assembly, re -testing the backflow assembly and updating the data base and meter inventory. The utility is requesting establishment of an hourly rate to recover the labor costs incurred to relocate the hydrant meters and backflow assemblies. Additionally, there are instances when a backflow assembly has been damaged and the utility needs to repair it prior to placing it back into service. The utility is also requesting authorization to recover the material costs to repair damaged equipment. The costs to perform duties associated with relocation of hydrant meters and backflow assemblies are as follows: Labor 1 hour at $23.74 per hour $23.74 Benefits at 30% of gross wage 7.12 Total labor costs: $30.86 It typically take approximately 1 hour to relocate the hydrant meter and complete the testing on the backflow assembly. In the past, repairs have taken anywhere from 30 minutes to 2 hours to complete. The utility is requesting establishment of an hourly rate and the ability to recover the utility's cost for materials as shown below: Description Actual Cost Proposed Rate Labor $30.86 per hour $31.00 per hour Materials Utility's cost Utility's Cost APPENDIX E 5-YEAR CAPITAL IMPROVEMENTS PLAN 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 o O o 0 0 o e O O O O O O O O O O O O O O o O O O O O N N o O O O O O O O O O O O O O N N_ o O O O o O O O O O O Ifl G O N G o O O O O O O f0 O O O O In O O (D O 10' F A O N O (O A OG N N O M N N N C'J O tp N T O N O N O N (D N A O N O M Q N N N N' Q N T N w w w w w w w iA w w w w w w w w w w M w w w w w O O O � O O N O O C N N N N w w w w w O O O O O O O N O O O O O 0 O N N O N w N w w w w w w O O O O O O O O O O O O O O O H O o O O O O O A O O O N N O O N N N' IZ w w w w w w w w N U U O o 0 o O o 0 0 0 0 0 0 0 0 A pO O O O N O O O O N O O O O O 00 N O N O O O O O O N O OO O O O O O to N N O O O O O (p O G O 10 tp N N N N M N M O N O N O N O N A A N O N O N M V A A 0 N w w w w w w w w w w w w w w w 0 0 0 0 00 0 o e o 0 o O o m O O O e o a o 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 CO 0 0 0 OM O f0 (O W t0 0 N w w w w w w w w w w w w U � U m@ `o, m@ m@@ Z Z Z Z m rn m a m m o.

The project is a partnership between the Town's Stormwater Utility, Water Utility and others to design and construct a detention facility for capturing and temporarily holding stormwater runoff during a significant rain event. The project proposes to take advantage of natural existing conditions to diminish flood peaks downstream of Big Wash and create a collection area within the existing flood plain to allow for enhanced natural recharge. The long term goal of this project is to design a facility and gather data that would enable the Utility to identify other potential detention sites within Town limits. The intent is to develop these sites in the future and to significantly enhance natural recharge capabilities offsetting supply issues due to drought and continued growth. Funding is being sought by the Stormwater Utility through Pima County Flood Control District CIP funds. Big Wash Multi -Use Pilot Project ORO VALLEY COMMUNITY DISPLAY GARDEN n n n n n ORO VALLEY COMMUNITY DISPLAY GARDEN n n The Oro Valley Community Display Garden is nearing completion of design and moving forward toward the fund raising phase. The garden encompasses a multi -use theme in which donor recognition is prominently displayed as a feature of its design. Within the proposed 0.8 acre site will be magnificent views, sustainable solutions for water usage issues, pleasant shaded oasis areas, meeting areas, conservation education gardens and educational displays of graywater and rainwater harvesting techniques. Included in the design is an event area for special presentations, traveling exhibits and programmed activities for groups. A gathering area, screened by vegetation with a spectacular back drop of Pusch Ridge, will do double duty as a rentable decorative area for private and public functions and ceremonies, as well as provide a public use area that is shady, quiet and relaxing. Along with the Town library and Farmer's Market, the Oro Valley Community Display Garden will contribute to a sense of place for Town Hall. Citizens can gather at the Town Hall for reasons other than business and administrative concerns. Oro Valley residents will soon come to its garden for fun and relaxation; a center from which to draw a sense of community. Funding for the garden consists of a three-way partnership. The Town library is a contributing partner sharing input to promote the project and seeking grants to help fund operation of the garden in the future. Town management, Mayor and Council and all of the Town's departments represent the second partner and are contributing the space for the project, providing design and engineering input, equipment and much of the labor involved as well as assisting with promotion and fundraising efforts. The Town Utility is providing project oversight, overall design services and will be seeking grant sources for funding as well as promoting the use of the garden. The third partner in the project is the citizens of Oro Valley. Their support will provide much of the funding and help with the installation of equipment and planting. Earth Day Celebration 2005 will kick off the fund raising phase of the garden. It is anticipated that construction could begin by winter of that same year.
