LA CANADA DRIVE CALL TO ORDER: 7:00 p.m. PRESENT: Oro Valley Town Council: Paul Loomis, Mayor Dick Johnson, Vice Mayor Wayne Bryant, Council Member Francis LaSala, Council Member Paul Parisi, Council Member Marana Town Council: Michael Reuwsaat, Council Member Roxanne Ziegler, Council Member Herb Kai, Council Member Ed Honea, Council Member MDWID: Sam Ray, Chairman Herb Johnson Peter Schlegel Marlene Wright INA ROAD WPCF RECLAIMED WATER DISTRIBUTION SYSTEM FEASIBILITY STUDY - PIMA COUNTY Chuck Huckleberry, Pima County Administrator stated the discussion talks about options available to deliver reclaimed water or effluent for users in the northwest side of Tucson and to substitute effluent use for present groundwater utilization for mostly turf irrigation. He stated they are currently involved in litigation with the City of Tucson over this matter. He referred to the IGA between City of Tucson and Pima County giving the city the rights to the effluent, however, he stated there are 28,000 acre feet being discharged into the Santa Cruz River for which there was a possible beneficial use other than simply discharge. Based on that information the county commissioned a study with the engineering firm of Malcolm Pimie to determine if there was any economic feasibility to actually purchase that effluent from the Secretary of Interior to compensate the Indian nations for Indian water rights settlement, and then at the same time, repay the capital costs of infrastructure and distribution systems necessary, and to provide this reclaimed water for turf irrigation within water service areas and users in the northwest. 04/28/99 Minutes, Oro Valley, Marana & MDWID Study Session 2 Mr. Huckleberry stated that the result is that'it appears to be feasible and economically viable to construct a separate reclaimed water distribution system, originating at the Ina Road Treatment Facility to serve the Towns of Oro Valley and Marana and those users in the Metro Domestic Water Improvement District. He pointed out the county's role is one of a facilitator and they would like to see less effluent discharged in the Santa Cruz River and more effluent put into beneficial use and turf irrigation substituting for groundwater use. He stated this is the first step in that direction. He stated it will require more intensive economic analysis with respect to what pieces get built first, who pays and who contracts for the delivery. How to negotiate a reasonable price of SAWRSA effluent available from the Indian nation through the Secretary of Interior. Mr. Huckleberry expressed his appreciation for the jurisdiction's support and he hopes to build on the relationship and talk about moving this project towards implementation. He pointed out that this project will require a lot of action besides Pima County. He stated that Pima County will only use up to 10% of the effluent available to irrigate county parks. -- Pima County Wastewater Director George Brinsko introduced Steve Davis, Senior Associate and Project Manager with Malcolm Pimie and Glen Oger, Senior Project Scientist and Deputy Project Manager who then reviewed the draft reclaimed water distribution system report. Mr. Davis stated his firm was hired in November 1998 to develop an Economic Feasibility Assessment of a northwest service area reclaimed delivery system that would emanate from the Ina Road Wastewater Treatment Plant. Mr. Davis and Mr. Oger reviewed the Ina Road WPCF Reclaimed Water Distribution System Feasibility Study (draft dated April 1999). The six major project tasks included: o Preliminary investigation and collection of data. Pipeline route study Evaluation of surface and sub-surface storage requirements for reclaimed water and effluent. Evaluation of treatment to achieve different end user water quality requirements (both for open access landscaped irrigation, such as parks, golf courses and recharge). Development of conceptual designs for different facilities to meet the projected demand. Optimization study that will look at ways to reduce the cost and optimize the sizes of the systems. The study area includes the Towns of Marana and Oro Valley, Metro Domestic Water Improvement District and Flowing Wells Irrigation Districts. Mr. Davis showed the location of the 3 different corridors along the Canada Del Oro. 04/28/99 Minutes, Oro Valley, Marana & MDWID Study Session Mr. Brinsko stated no direction is required at this time from the jurisdictions in the northwest area. He stated updated reports will be given periodically. The final report will be completed as soon as possible, but no date for completion has been anticipated at this time. ADJOURNMENT Meeting adjourned at 8:30 p.m. Respectfully submitted, Kathryn Cuvelier, CMC Town Clerk I attest that the foregoing minutes of the Oro Valley Town Council Joint Study Session with Oro Valley Water Utility Commission, Marana Town Council, and Metro Domestic Water Improvement District Board of Directors, held April 28, 1999 at the Oro Valley Town Council Chambers, 11000 N.
