2025 Urban Water Management Plan

Section 3 2025 Urban Water Management Plan Service Area Description City of Pleasanton Public Draft | May 2026 3-12 EKI Environment & Water, Inc. 3.5.2 Non-Potable Water Distribution System Over a decade ago, Pleasanton established its recycled water program with a goal of using recycled water in place of potable supply to meet irrigation demands along the alignment of its non-potable distribution system. The City purchases recycled water from DERWA and Livermore. In June 2015, construction began on Pleasanton’s Recycled Water Project (RW Project) with funding supported through a Clean Water State Revolving Fund Program loan and Proposition 1 Program Grant Agreement with the SWRCB. The City substantially completed construction of the RW Project by September 2016. The construction involved installing approximately 51,500 linear feet (LF) (or 9.8 miles) of new recycled water pipeline, ranging in diameter from 6 to 20 inches, and repurposing approximately 22,400 LF (4.2 miles) of existing potable pipeline for recycled water distribution. The recycled water pipelines connect to DSRSD’s RWTF and the City’s existing 8 million gallon (MG) recycled water reservoir (Tassajara Reservoir), which was converted from a potable water storage facility in 2017. In 2019, the City also added a new recycled water pump station at the Ken Mercer Sports Park. Livermore supplies recycled water to the northeast portion of Pleasanton. The City constructed that portion of the recycled water system concurrently with new development projects and initially began serving recycled water in 2013-2014 under Livermore’s recycled water permit coverage, until Pleasanton obtained authorization under its own permit coverage in July 2015. Currently, the City has 98 permitted sites with 150 metered connections (out of 161 targeted connections).
