the agreement, they have outlined how the infrastructure would be shared in a way that accounts for <br /> Pleasanton's previous contribution. The agreement with DERWA, which is a Joint Powers Authority <br /> comprised of DSRSD and EBMUD, establishes the rate and terms under which DERWA provides <br /> tertiary treatment of the secondary effluent and delivers the final product to the city for distribution. <br /> Councilmember Brown asked and Mr. Smith confirmed that recycled water use at CLC is for irrigation, <br /> not drinking water. She referred an earlier comment he made that it would require 67,000 years worth <br /> of play on a lawn irrigated with recycled water for a child to absorb or ingest the equivalent of one dose <br /> of Advil. She asked then whether minute quantities of drugs or other dissolved materials make their <br /> way through the treatment process and into irrigation. <br /> Mr. Smith explained that recycled water used for irrigation is subjected to a tertiary treatment process, <br /> which does not remove all chemicals from the water and does provide for minute exposures over <br /> exceptionally long periods of time. Reverse osmosis is the method used to remove the majority of <br /> chemicals for consumption purposes. <br /> Mr. Smith continued his presentation. He showed several slides of existing infrastructure and <br /> demonstrated the proposed implementation of the recycled water program. Phase 1 includes the <br /> current agreement with the City of Livermore to temporarily service certain portions along the east side. <br /> Phase 1A forms the backbone of the distribution system from the west end of Pleasanton, connecting <br /> the DSRSD/DERWA tertiary treatment facility to major sections of Hacienda Business Park as the <br /> pipeline makes it way to the existing 8 million gallon Tassajara Reservoir for storage capability. Phase <br /> 1B looks at extending the service to additional portions of Hacienda and the east side, potentially at the <br /> expense of future developers. In terms of capacity, Phase 1A provides approximately 3 million gallons <br /> of recycled water per day and Phase 1B nearly 4 million gallons. <br /> The expansion of water treatment capacities beyond the 2 million gallons currently available through <br /> DSRSD and DERWA is estimated to cost $1.4 million. Distribution costs for Phase 1A is nearly $11.5 <br /> million and Phase 1B almost half that. The current sale price for potable water is $1,074 per acre foot <br /> and is projected to reach nearly $1,400 per by 2020. Because it is illegal in California to sell recycled <br /> water for more than potable water, staff is recommending an interim charge of 90% of the potable water <br /> price. Using 2020 estimates, recycled water would cost consumers $268 per acre foot less than potable <br /> water. In looking at the cost versus benefits, the study determined that even with financing the city can <br /> expect to pay about $900 per acre foot and resell the same acre foot for about $1,125. <br /> Staff is requesting the following action by the Council: approve the Recycled Water Feasibility Study <br /> and Water Supply Contracts with DSRSD and DERWA, authorize staff to start detailed environmental <br /> analysis, authorize staff to submit grant and loan applications, and authorize an expenditure of $40,000 <br /> from the Recycled Water Fund to purchase recycled water from the City of Livermore for the remainder <br /> of 2013. <br /> Mayor Thorne asked and Mr. Smith confirmed that recycled water supplies at Val Vista are for the park <br /> only and not the development. He also asked whether staff had any information on the status of the <br /> Delta fix water bond. <br /> Mr. Smith said the bond is still on for 2014, though polling indicates it will fail again. A new group of <br /> legislators have prepared a new $4 billion bond for the project, but there is some concern that the <br /> Governor will not move forward with it because of the upcoming reelection. The general expectation is <br /> that it may be 2016 before any type of water bond passes. <br /> Councilmember Pentin noted that the proposed program does not service Callippe Preserve Golf <br /> Course, which is the single largest source of water consumption by the city. <br /> City Council Minutes Page 4 of 13 November 5, 2013 <br />
