BACKGROUND The City of Pleasanton recognizes the critical role of recycled water in providing a reliable water supply to its customers and in meeting water conservation goals as requested by the Governor and the State Water Board. Dublin San Ramon Services District (DSRSD) and East Bay Municipal Utility District (EBMUD) Recycled Water Association (DERWA) and the City of Pleasanton entered into an agreement January 7, 2014 to provide recycled water treatment and delivery services. The first phase of DERWA facilities expansion construction included the Pleasanton owned Sixth Filter project which was completed April 2016. The first phase sixth filter project provides the City with a recycled water supply of up to 1.9 million gallons per day (mgd) of supply which is delivered to irrigation customers. On January 24, 2017, DERWA and the City of Pleasanton entered into a Temporary Water Supply agreement that allowed DERWA to purchase potable water from the Pleasanton turnout to cover intermittent temporary recycled water outages. DERWA completed the second phase of facilities expansion in February 2018, which provides Pleasanton the rights to a recycled water supply of up to 4.2 mgd, which should be adequate to meet max-day irrigation demands for all existing and future Purple Pipe customers. DISCUSSION Following the completion of the expansion project and operating the DERWA plant during the 2018 irrigation season it was determined that a permanent potable water supply would benefit recycled water operations and provide potable water during periods of water shortages/outages and system maintenance. If prolonged outages in the recycled water supply occurred, significant harm may occur to public amenities such as parks and school yards, as well as private landscaping, therefore it is prudent to have a backup plan to mitigate those possibilities. Supplementing the recycled water supply with potable water is the most feasible temporary solution, and because neither DSRSD nor EBMUD have potential potable service connections in the area of the DERWA treatment plant, it makes sense that Pleasanton, who is an active partner in the recycled water project, provides the necessary connection and temporary water supply as may be required. Both the City Attorney's office and DERWA counsel have reviewed and approved the agreement. DERWA will be presenting the agreement to their Board for approval at their next scheduled meeting to be held on July 22, 2019.
