LA CANADA DRIVE t(' (o -p) CALL TO ORDER ROLL CALL PRESENT: David Powell, Chair Rick Davis, Commissioner Robert Milkey, Commissioner Elizabeth Shapiro, Commissioner John Hoffmann, Commissioner EXCUSED: Winston Tustison, Vice Chair STAFF PRESENT: Philip C. Saletta, Water Utility Director Shirley Seng, Utility Administrator David Ruiz, Engineering Division Manager Robert Jacklitch, Project Manager Jim Peterson, Water Utility Regional Coordinator CALL TO AUDIENCE Mr. Vince Vasquez, resident in Tucson had several questions regarding Rainwater Harvesting and the Landscape Ordinance. Chair Powell mentioned that his questions would be covered under Item #2. 1. APPROVAL MAY 11, 2009 MINUTES MOTION: A motion was made by Commissioner Milkey and seconded by Commissioner Shapiro to approve the May 11, 2009 minutes. MOTION carried, 5-0. 2. REVIEW OF PROPOSED GRAY WATER ORDINANCE Mr. Saletta reported the following: -Packet information: T.C. Communication prepared by Bayer Vella, Planning & Zoning describing the proposed Gray Water Ordinance. -Gray Water Ordinance: The proposed ordinance specifies plumbing requirements and e 6/8/09 MINUTES, ORO VALLEY WATER UTILITY COMMISSION implementation to new homes establishing gray water systems which can be installed without significant additional construction or expense to retrofit plumbing. -Gray Water Basic Concept: Allows showers and bathroom sinks to drain to a separate gray water system. Toilets, kitchen sinks and dishwashers which would discharge to the sanitary sewer. These are two separate plumbing systems they could join but there must be a valve separating them. In addition washing machines are required to have a valve and plumbing for a gray water system. -The ordinance is a Building Code\Planning and Zoning ordinance the Water Utility was involved through our Conservation Specialist. The Water Quality staff also participated to address issues on backflow prevention devices. A residence using a potable water system drip irrigation system would require a backflow prevention device for any gray water system built in the future. The ordinance does not mandate the use of gray water systems rather; it allows waste plumbing to be installed in a home for future use. This ordinance is very similar to the City of Tucson ordinance. -Staff recommends that the WUC support the proposed ordinance which will be considered for approval by Council at their meeting on Wednesday, June 17th. Questions & answer session occurred: -Would the sewer surcharge go down if a resident is using a gray water system or are there any type of incentives? (Commissioner Davis). Mr. Saletta indicated that the surcharge would be something Pima County Wastewater would have to consider. The Town and the Utility does not have any jurisdiction on fees or the setting of sewer fees. Wastewater billings are determined based upon indoor water use during the winter months, so the billings may not change. -How would Pima County know that the water went into a graywater system if sewer rates are based on metered water? (Commissioner Milkey). Mr. Saletta indicated that they wouldn't know if a gray water system existed, but it would be based on water used for irrigation which is generally reduced during winter months. Mr. Saletta pointed out that the sewer fees are based upon what goes through the water meter during the months of December-February. Commissioner Davis commented, we cannot incentivize residents to use less water by lowering their sewage because we have no jurisdiction over those sewer charges. Commissioner Milkey indicated that he discussed the ordinance with Mr. Saletta, Bayer Vella, and John Holden from Planning & Zoning. He also mentioned it was clear there were no risks to the Water Utility from fees and engineering issues. He explained that backflow protection was clearly defined and there are advantages that could impact long term water conservation. 2 6/8/09 MINUTES, ORO VALLEY WATER UTILITY COMMISSION Mr. Milkey indicated that it addresses customer's long term incentives regarding water usage, water conservation, possible savings and lower water bills. There is a need for public education, explain the advantages of installing a gray water system; if plumbing is available what are the advantages, and how to operate the system properly. Question and answer occurred: Commissioner Shapiro requested clarification on unutilized stub outs. Is there any way to divert water and is there a possibility of contamination? Mr. Saletta explained that there was a specific valve diverter that the resident could control to prevent backflow from the sewer coming back in the home. Commissioner Shapiro asked, is there a separate diverter for the use of a washing machine? Mr. Saletta explained the ordinance states that you can have a separate washing machine diversion and valve to connect into the gray water system. Commissioner Milkey commented that the use of a washing machine for gray water would probably be inexpensive. Commissioner Hoffmann asked, is there an ordinance for retrofitting a gray water system to existing homes? Mr. Saletta indicated that there was an ordinance in place and that a customer could install a gray water system in accordance with ADEQ standards and regulations; however their plumbing must be retrofitted and that could be costly. Commissioner Davis pointed out Section 101.11-Collection Reservoir under the International Residential Code that states the collection reservoir shall be closed in a gas-tight vessel. Item 3 also stated the reservoir must be vented, he requested some clarification. Mr. Saletta pointed out the sections were addressing proper ventilation and installation of a leak proof container and he would discuss this with Town Staff. A discussion took place about retrofitting of older homes and its long term advantages. MOTION: A motion was made by Commissioner Milkey and seconded by Commissioner Shapiro to recommend to Town Council approval of the Residential Gray Water Ordinance requiring installation of gray water plumbing in residential construction by amending the Oro Valley Town Code, Article 6-1, and the 2006 International Residential Code. MOTION carried, 5-0. Mr. Saletta indicated that the item would be forwarded to Council for approval on June 17, 2009. 3 6/8/09 MINUTES, ORO VALLEY WATER UTILITY COMMISSION Call to Audience: Chair Powell recognized Mr. Vince Vasquez, Diamond Ventures Representative. Mr. Vazquez had several questions regarding Rainwater Harvesting, and Landscape Ordinance/Codes and whether it was drafted similarly to the City of Tucson.

Council approved a severance package to any employee that would make a request within a 45 day period as of June 4th. -The Public Hearing for the Final Budget Adoption is scheduled Wednesday, June 17th. Vice Mayor Carter clarified Council's decision regarding the severance package. Mr. Saletta indicated he had not heard from any Water Utility employees at this time. -State of Arizona Senate adopted a budget for a 3-year moratorium on Impact Fees and Sweep of Vehicle License tax revenues this moratorium will impact the General Fund. Several of the departments that could be affected by the moratorium are the Water Utility, Public Works and Police Department. This bill has not been approved or presented to the 5 6/8/09 MINUTES, ORO VALLEY WATER UTILITY COMMISSION Governor. If the Water Utility's Impact Fees are affected, the Utility could experience a revenue reduction of$700,000 to $1,000,000 per year. This is based on preliminary calculations. Typically the Water Utility's water sales are in the $13-$14 million dollar range. Staff has more work to do on the water rates analysis. Passage of this bill has yet to be confirmed. Question and answer session occurred: -In answer to Commissioner Milkey's question, Mr. Saletta clarified that according to the Town's e-mail it will affect the collection of existing Impact Fees.

Chair Powell requested that Staff contact the Commission via email if they needed some support. Question and answer session: -Commissioner Milkey asked, is there anything keeping it from being too overly restricted to the Commission for example, the issue regarding impact fees or other issues? Ms. Seng commented there were no restrictions; the Commission could present any number of scenarios to Council. -Commissioner Milkey asked, is there any opportunity for the Commission to participate at Council's Study Session? Mr. Saletta indicated that he would discuss it with the Town Manager and the Mayor. The Mayor may recognize the Commission but usually does not allow the public to speak because the public has the opportunity at Council meetings. Study Sessions are working sessions for Council information, updates and preliminary discussions. A short discussion occurred regarding the installation of a second meter or submeter for irrigation only and how it could affect impact fees and the purchase of a second meter. (Commissioner Davis).
