In response to Mayor Brown's inquiries, Director Yurchak confirmed Pleasanton is Zone 7's largest water reseller and that the studies account for an ongoing decrease in wastewater due to home technology advances like high efficiency washing machines.

In response to Mayor Brown's inquiry, Director Yurchak could not immediately provide the cost of a potable reuse system and its various options. Mayor Brown stated a 2018 staff report estimated the cost at $222 million. Director of Operations and Water Utilities Yurchak stated potable reuse came in as between $2,200-2,500 per acre-foot. Mayor Brown commented the current cost is $640 per acre-foot and the California Water Fix is $740.

She also confirmed they are not making decisions today on future costs associated with potable reuse. Mayor Brown opened public comment. Angela Ramirez Holmes stated she joined the Zone 7 Board of Directors to help foster relationships with retailers like her hometown of Pleasanton which has led savings to customers through collaboration between retailers. She stated that while she is unsure about potable reuse there is a due diligence responsibility to research this requested local option. She noted the Council unanimously approved considering this research in 2018 and asked the Council to follow through on its commitment and good faith negotiation alongside its regional partners to study this locally controlled option. Olivia Sanwong concurred with Ms. Ramirez and noted she ran for the Zone 7 board because she believes in collective partnerships for the region's good and shared groundwater basin. She stated Zone 7 has the authority to proceed without Pleasanton but would rather do so with her hometown's input. She stated she has no opinion yet on potable reuse but urged the City to continue to be part of the conversation once the study is completed. She added there have been multiple droughts since the General Plan was written and with more forecasted the potable reuse option should be considered. In response to Mayor Brown's inquiry, Ms. Sanwong clarified her recent "no" vote on Zone 7's Delta Conveyance Project by stating it was to allow more time to assess the differences between former Governor Brown's twin-tunnel proposal and current Governor Newsom's single-tunnel proposal, and to provide more time for the community to be heard. Matt Maciel expressed his hesitancy as a resident about using potable reuse water and encouraged the Council to spend the money elsewhere. City Council Minutes Page 6 of 12 February 2, 2021
