Carter, Council Member Conny Culver, Council Member Helen Dankwerth, Council Member EXCUSED: Terry Parish, Council Member WATER UTILITY Mike Caporaso, Chair COMMISSION: Gregg Forszt, Member Leo Leonhart, Member EXCUSED: Erin Loudermilk, Member Ray Montoya, Member Steve Rivera, Member REVIEW AND DISCUSSION—DRAFT GRAY WATER ORDINANCE Codes Administrator Terry Vosler reviewed his report outlining findings on the Building installation of writinga water conservation ordinance mandating the of Hot Water Recirculation Systems or Point of Service Systems and/or requiring the installation of Dualpg Systems Waste Pi in S stems in new dwelling units constructed. Either of the recirculation systems would conserve some water (approximately 10 to 15 gallons peryday per averagehousehold) byproviding hot water to plumbing fixtures without running water down the drain while waiting for the water to get hot. The Dual Waste Piping Systems would allow easyaccess to "grey water" in order to reuse for watering landscape vegetation. He explained that existing ordinances dealing with Hot Water Recirculation Systems were researched in Sierra Vista, Marana, Goodyear, and in Cottonwood for the pg Systems.DualWaste Pi in S stems. Tucson Electric Power was also consulted concerning usage rates in the use of Hot Water Recirculation Systems and Point of Service Systems. Ed Taczy, nowsk Southern Arizona Homebuilder's Association (SAHBA) thanked the • Council for the studysession and asked to help put together an ordinance. He explained 01/24/05 Minutes,Joint Town Council& 2 Water Utility Commission Study Session that SAHBA endorses House Bill 2323 that allows for water conservation tax credits. 40 to explore how the grey water ordinance should be structured SAHBA would like p addressing issues such as: • How soaps and detergents in the grey water affect plants. • Unsightly appearance of installation of stubs to homes. g y p • Rodents downspouts usingdowns outs for access to roof vents and destroying house insulation. • Preventing breeding grounds for mosquitoes. • Recirculation pumps having different electrical outlets and not allowing water to drip onto them. • Volume ofq required liquid to move solids through the sewer—how will taking that water out of the sewer affect the transmission of the solids. Doug McKee, member of Planning &Zoning Commission stated that if this is installed and is successful in reducingthe amount of water going to Pima County, thus reducing the amount of reclaimed water, longrange planning should be done to see how that reduced amount of reclaimed water coming back to Oro Valley is affected. Member Abbott asked that information obtained by Planner Bayer Vella Council M concerning incentives for water conservation be obtained and distributed to the Council. Mayor Loomis asked if the Council wanted an ordinance requiring Hot Water . 1111 Systems or just offer incentives to reduce people's water consumption. He Recirculation y stated that Council should look at the feasibility of this and the recommendations from the Water UtilityCommission as to whether we should adopt an ordinance or look at incentives without requiring it by law. REVIEW AND DISCUSSION OF WATER CONSERVATION SUB- COMMITTEE ACCOMPLISHMENTS Conservation Specialist Kevin McCaleb reviewed a power point presentation Water p giving an overview of the Water Utility's current Water Conservation Program consisting of the following 5 elements: • Incentives—Distribution of rain sensors to town residents. • sultations —Town Departments; Homeowner's Associations; Developers; Con p Residentiallandscapeprojects; Household water management and golf courses.• Audits— 150 residential audits completed; 11 commercial audits completed; Riverfront Park audit 2/3 complete. —Partnerships with manufacturers (smart controller technology, soil • Research p moisture sensor). Town Hall irrigation/landscape project (irrigation alternatives to drip systems). • Edu cation —Professional organizations; provide information on new technologies andprovidetraining trends; to staff in current water management technologies and methodologies; network of resources; demonstrations; audits; rain sensor • installation classes; seminars; newsletters; Community Display Garden; pamphlets and literature; staff education. 01/24/05 Minutes,Joint Town Council& 3 Water Utility Commission Study Session • Current Affiliations—AWWA; IA; Water CASA; ARCSA. • • Projects in Development—Oro Valley Community Display Garden; Big Wash P multi-usep ilot project; Residential rain water harvesting project. • Program Goals—Town-wide conservation policy; residential classes for irrigation management and maintenance; classes for landscape/irrigation contractors; outreach representation on the Development Review Committee. • Issues — g Ex andin the incentive base; adopting specifications, ordinances and Expanding codes to reflect conservation commitment; increased staffing. Discussion followed regarding: • The difficulty in quantifying residential water sensor usage due to factors such as weather patterns. • The WaterCASA is trying to quantify water conservation in our region. • Concentrate on the largest water users in the Town, such as the town itself. The Water Utility Commission and employees can suggest plants and watering for Town medians,parks and for large developments at the beginning of major commercial projects. • The existing low water usage policy for Town medians and having the WUC review those and recommend any changes they may have. • Since we have limited resources, WUC & staff should look at prioritizing water conservation programs to get the most "bang for the buck"until our Water Conservationist is given more resources. • Important to make sure the water conservation programs are balanced to get the areas that give us the most"bang for the buck"while maintaining a mindset in the community to embrace the concept of conservation and give them the opportunity to participate. Mayor Loomis called a recess at 7:40 p.m. Meeting resumed at 7:45 p.m. REVIEW AND DISCUSSION OF THE PROPOSED TOWN COUNCIL WATER POLICY AMENDMENTS Water Utility Director Alan Forrest reviewed revisions to the Water Policies adopted in 1996. In response to a question by Council Member Dankwerth, Mr. Forrest explained how a 100y ear Assured Water Supply is determined by the Arizona Department of Water Resources. He explained that the analysis and water modeling submitted to the State had to include areas north of the Oro Valley Town limits since they are using the same aquifer. Mr. Forrest will distribute copies of the 100 Year Assured Water Supply Executive Summary to the Mayor and Council. The following changes were discussed: • • Add a general definition for the word "aquifer" and "renewable water supply." 01/2X4/05 Minutes,Joint Town Council& 4 Water Utility Commission Study Session • Page 2—rewrite 1.f. the paragraph "reducing water rates and/or reduced P ag development impact fees"will not be allowed. • Page 3 (4)—reword to allow flexibility. • b. 3 • Page a e — sentence should read "Rate structures shall be designed so as to encourage water conservation." • Page 5 —Add (5) "Operating and Maintenance costs."• Page 6—2.a. insert wording regarding ability to "lease." Mr. Forrest will make the changes and get to the Water Utility Commission at their February 7, 2005 meeting. This item will be considered at the March 2, 2005 Town Council meeting. In responserequestby to a Council Member Abbott, Mr. Forrest reiterated that he will provide Council with the Assured Water Supply Executive Summary. He stated that the entire document is available for review. He will provide some type of graph showing what the Town's water supply is,how much of that water is currently used or committed for development, and how much water is left for growth.

TOWN OF ORO VALLEY COUNCIL STUDY SESSION MEETING DATE: January 24, 200 TO: HONORABLE MAYOR& COUNCIL FROM: Terry Vosler, Building Safety Administrator SUBJECT: Report on grey water and other potential water conservation proposed Ordinances. SUMMARY: This is a report outliningfindings on the feasibility of writing a water conservation ordinance mandating the pg installation of a Hot Water Recirculation Systems or Point of Service Systems and\or requiring the installation of Dual Waste Piping Systems in new dwelling units constructed. Either of the recirculation systems would p g y conserve some water( pp a roximately 10 to 15 gallons per day per average household)by providing hot water to plumbingfixtures without running water down the drain while waiting for the water to get hot. The Dual Waste Piping Systems would allow easy access to "grey water" in order to reuse it for watering landscape vegetation. p g y Duringtheprocess of generating this report, existing ordinances dealing with Hot Water Recirculation Systems were researched in Sierra Vista, Marana, Goodyear and in Cottonwood for the Dual Waste Piping Systems. Tucson Electric was also consulted concerning usage rates in the use of Hot Water Recirculation Systems and Point of Service systems. Hot Water Recirculation System: A Hot Water Recirculation System is a system where a circulation pump is installed to circulate hot water in all the hot water piping of a dwelling unit. The pump circulates the water in the hot waterpp i es through the water heater in order to maintain a consistent water temperature in the hot water . The pumpis generally thermostatically controlled so the pump is turned on when the water reaches a piping. certain temperature. This type of system will substantially increase electric power consumption and when the p � water heater is naturalg as operated, the gas consumption will also significantly increase. Sierra Vista has an ordinance requiring the installation of Hot Water Recirculation Systems. This system is more costly in g installation and operation than Point of Service Systems. Sierra Vista reported that they experienced several difficulties in the enforcement of their ordinance (see Exhibit A attached). Point of Service Systems: A Point of Service System has a smaller circulation pump typically installed in each bathroom and in the kitchen. Thep ump circulates the water in the hot water line back to the water heater. The pump is installed under the kitchen sink and under the bathroom lavatory sinks and serves only that plumbing fixture. Theum is controlled by a switch and is automatically turned off when hot water reaches the pump. p p This type of system consumes very little electricity and does not have a significant impact on natural gas � y consumption in maintaining the water temperature in gas fired water heaters. Goodyear has an ordinance requiring the installation of electrical outlets under the counter in each bathroom and kitchen to allow for future q g installation of circulation pumps at these locations. This way if the occupant wants the circulation pump installed they will not have to install the electrical wiring, outlet and switch for the system; they would simply plug pump thein and connect it to the lavatory sink. Goodyear reported that the approximate cost of installation of the wiring and outlet for the future pump is $100.00 per electrical outlet installed. One electrical outlet is required in each bathroom and in the kitchen. Attached, as Exhibit A is a copy of a Report to Water Utility Board on Hot Water Recirculation Pumps and Systems. TOWN OF ORO VALLEY COUNCIL COMMUNICATION Page 2 of 3 Dual Waste Piping Systems Cottonwood is the only jurisdiction discovered that has an ordinance requiring the installation of dual waste piping systems. The Town of Marana offers a reduction of permit fees for the voluntary installation of grey water recovery systems. When contacted the Cottonwood Building Safety Department reported that there was no resistance from the local builders in adopting this ordinance. The average cost increase per residence constructed was reported to be approximately$400.00. This cost estimate does not include the cost of the installation of the grey water distribution system. A major Tucson plumbing company was also contacted to obtain an estimate. The estimate provided was between$250.00 and $300.00. The owner of the company stated that the installation should not be overly burdensome since the grey water piping could be installed in the same trenches as the waste piping. Single-family dwelling grey water systems, when fully utilized, have the potential of recovering approximately 119 gallons of grey water per day for use in landscape watering. Attached as Exhibit B is a report entitled Potential Water Savings for Oro Valley Single Family Residences Using Graywater Harvesting Systems. This report was prepared by Oro Valley Water Conservation Specialist, Kevin McCaleb. FISCAL IMPACT: The fiscal impact of approving an ordinance requiring Point of Service Recirculation systems and Dual Waste Piping Systems would be an increase in construction cost of single family dwellings of approximately$1,000 for an average home with two bathrooms. There would also be costs for education of the public and staff in the installation and use of these systems. The additional costs to staff would not significantly affect the approved 2004-2005 fiscal year budget for the Building Safety Division. RECOMMENDATION: If some sort of ordinance were desired to help conserve water in the use of hot water in single-family dwellings, staff recommends adopting an ordinance requiring the installation of outlets in bathrooms and kitchens that will allow easy installation of future Point of Service Recirculation Systems as the City of Goodyear has done. An ordinance requiring the installation of Dual Waste Piping Systems in all new single-family residences constructed has the potential of saving a considerable amount of water. The data attached as Exhibit A indicates that an average of 3,742 gallons of grey water could be recovered per month per average single-family dwelling. If an ordinance is desired to mandate the installation of Dual Waste Piping Systems staff recommends that the piping system be installed and terminate five (5) feet outside the building. This would allow for the installation of single family dwelling grey water irrigation systems to be installed, with appropriate permits, without affecting the existing construction within the residence.

During the process of generating this report, existing ordinances dealing with this type of installation were researched in Sierra Vista, Marana, and Goodyear. Tucson Electric was also consulted concerning usage rates. Summary of Data: All of the municipalities contacted reported the same difficulty in enacting an ordinance of this type. How can the costs of operation be justified by the amount of water conserved? Sierra Vista, the only one of the three that has this type of ordinance in place, reported difficulties in getting builders to comply. The ordinance was rewritten several times to limit "Contractor interpretation" and finally a detailed installation drawing was generated to limit inadequate and faulty installations. Marana could find little if any significant capture of water waste to support installation mandates and there by chose to offer installation as part of an overall conservation incentive option package. (Reduction of certain permit fees if installed)The package entails a group of conservation options of which Hot Water recirculation pumps and systems are but one. Goodyear as well was unable to produce data to warrant installation mandates and instead chose to treat it as a convenience. In their ordinance they mandate installation of power fixtures in appropriate locations instead. This gives the owner the option at some time to install a point of service unit if desired with out the expense of running new wire. Tucson electric provided the most significant data. They have performed multiple controlled tests and surveys specifically on power consumption of these systems. Their findings showed that power consumption for hot water rose substantially, as much as four times normal, when recirculation systems are installed. The use of thermostats and timers reduce that amount if monitored and used properly, still the rise in power consumption was significant. Research: Pipe size is the biggest indicator of how much water must be passed through the system prior to achieving hot water. Basically the cooler water in the line must be replaced by the hot. Using 1/2"type "K" copper for calculation, it was found that in a 100' run of copper, only a little better than 1 gallon would be lost (1.14) during replacement. Once that cooler water was replaced, until such time as static cooling occurred, the water would continue to be warm at the fixture. So typically,while the morning rush to work and school was on, the water would remain warm in the lines. When examining how a recirculation system works, it becomes apparent that the sub slab temperature in the home is significantly cooler than the water in the lines which are run there. This causes the water in the lines to cool dramatically. (the difference can be as much 50 degrees). In true recirculation systems, the static water in the lines is cooled rapidly and must be cycled into the water heater to be brought up to the required temperature. This causes an increase in the duration and frequency in which the heating unit must fire to re-heat the water being held. even with thermostats and timers, ambient heat in the lines will be tough to maintain. Point of service systems operate on the same principle, except that they use existing plumbing to accomplish the return. Their system operates only upon demand. The system has to be manually operated to avoid the same cooling as the recirculation system creates. If there is a demand of hot water, a switch must be operated to require the pump to move the hot water from the tank to replace the cooler water in the lines. These systems operate on the premise of being able to move the water quickly through the system and minimize cooling as the water travels through the pipes. Audit Data: One audit was performed on a two story house in the Monterrey sub-division area. Farthest fixture from the Hot Water Heater was tested. Water took 1.20 min to arrive hot. Total loss of water... less than %2 gallon. Summary: The concept sounds like a good idea, in fact in theory it would be. However with current construction practices it could conceivably cost a homeowner much more in power consumption than could be justified by water savings. More significant results could be made by insuring in the design of a home that long runs of piping are eliminated. That Hot water heaters are centrally located, or that piping was substantially insulated, regardless of application. If some sort of ordinance is still desired, then from the data collected, adopting an ordinance along the lines of what the city of Goodyear has done would be the most effective. EXHIBIT B Potential Water Savings For Oro Valley Single Family Residences Using Graywater Harvesting Systems The Arizona Department of Environmental Quality defines "graywater" as wastewater collected separately from a sewage flow that originates from a clothes washer, bathtub, shower and sink, but does not include wastewater from a kitchen sink, dishwasher or toilet.' A graywater harvesting system is the means by which it is captured and distributed for use on landscape. Identifying actual savings of individual residences is difficult to quantify with any accuracy because of varying water use habits and individual household conditions.Factors that may also affect water usage include: • Seasonal residents • The number and age of residents in any household • Size of the lot • Composition of the landscaping • Density of plantings • Swimming pools • Water treatment systems • Water features It is; however, possible to suggest margins of savings based upon average usage trends and capacities of the fixtures involved. The majority of homes in Oro Valley were constructed after "Low Flow" ordinances were enforced; therefore,the usage data assumes those fixtures are in place. Oro Valley Single Family Residence Water Usage Averages Average consumption per person: 120.0 gallons per day Average number of occupants per dwelling: 2.8 Average monthly consumption: 10,220.0 gallons 2 Potential Graywater Capture Per Household Activity Fixture/Appliance Gals/Minute Minutes/Use3 Gallons/Day Shaving: bath sink 2.5 5 12.5 Brush Teeth: bath sink 2.5 2 5.0 Showering: shower/tub 2.5 10 25.0 42.5 Laundry washing machine 1 load/week 40 gal/load Estimated daily usage 42.5 gallons/person x 2.8 residents= 119 gallons/household Estimated monthly usage 30 days x 119 gal/household/day= 3,570 gallons/month Estimated wash loads/month 4.3 x 40 gallons/load = 172 gallons/month Estimated graywater capture: 3,742 gallons/month ' Arizona Department of Environmental Quality Residential Graywater Reuse Rules(Effective January 2001) 2 These calculations are based upon population estimates and CY2003 water usage data 3 This number will vary according to individual preferences and number of occupants engaged in activity 2 TOWN!

Based on the utility's operations over the past 8 1/2 years, the Oro Valley Water Utility Commission and staff felt it was important to review, re-evaluate and update the policies where needed. The Commission spent several months reviewing and discussing the Water Policies before approving the proposed changes at their meeting in August 2004. The Mayor & Council Water Policies provide direction for the operation of the Water Utility. Upon adoption of the revised policies, the Commission and staff will return to Council with Ordinances to amend and/or change Section 15 of the Town Code so that the Water Policies and the Town Code are consistent with each other. Attachment #1 contains a "red line" version of the water policies which provides the original text of the policies along with the proposed changes. In some cases, the text was simply moved to a different location within the document for organizational purposes. Attachment #2 contains the proposed changes with no editing shown which may allow for easier reading. FISCAL IMPACT: None. ATTACHMENTS: 1.

Foremost among these values is the assurance of a life sustaining municipal water supply. It is, therefore, incumbent upon the elected officials of the community to implement a water utility policy that ensures present and future availability and delivery of quality water through responsible management of water resources. With the acquisition of the Town's municipal water systems, the Town Council established the Oro Valley Water Utility as a financially self-supporting enterprise. The Town Council has also provided guidelines for water Utility management and operation through promulgation of the Town of Oro Valley Mayor and Council Water Policies (M&C Water Policies). In recognition of water management issues such as increasing demand with population growth, annual diminishing of groundwater supplies, the need to meet local, state and federal water quality standards, along with economic and environmental factors, the M&C Water Policies reflect and support measures necessary to protect, sustain, enhance, augment and finance affordable water supplies for present and future Town of Oro Valley water consumers. I.-IL ASSUMPTIONS A. The Oro Valley Water Utility is established as a financially self-supporting enterprise. B.

This comes as a surprise, as SAHBA has engaged in dialogue with Council Members Dankwerth and Culver regarding a program of voluntary compliance where this program could be offered as an option on future construction. Council Members Danwerth and Culver suggested the formation of a committee with Ed Tacznowsky and SAHBA participating with the Town. SAHBA is sympathetic with the goals of the town to curtail use of our precious water resource. We have applauded the Town's policies on reclaimed water. We supported the water replenishment fees and the construction of the reclaimed water infrastructure. We are firmly in the conservation camp. Grey water, although it sounds good when you say it fast, has a few warts. In this light, we feel that it should be up to the individual homeowner to decide if they want to take part or not. After all, the homeowner is the one who writes the check. It is SAHBA's position that this should be administered on a voluntary basis with input from the Town. Suggested uses, systems and applications should be made available in order to increase citizen's awareness so that they are able make an informed decision. If this is mandated, then the Town should credit the builder for the cost of installation. We urge the Town to take care in this issue which might bring about unintended consequences.
