THE CITY OF Chapter 6 Water Supply Characterization PL£ASANTON 6.2.5.4 Potential, Current, and Projected Recycled Water Uses Recycled water improves water supply reliability, preserves potable water supplies, and reduces wastewater discharges. The City's recycled water users were originally serviced under the authority of DSRSD or Livermore's General Order 96-011. In April 2020, the City, Livermore, and DSRSD transitioned from Regional Water Quality Control Board (San Francisco Bay Region) General Order 96-011 to SWRCB General Order 2016. The City currently permits the following recycled water uses: • Landscape irrigation to designated irrigation meters • Construction water, dust control, and surface washing • Dual plumbing In 2020, the City had a total of 89 permitted recycled water irrigation sites, one permitted dual plumbing site, and one site permitted for construction use (dust control/soil compaction). No permits have been issued that include impoundments. Five new recycled water users received permits in 2020; all were for landscape irrigation. In 2020, these customers used approximately 1,224 AF of recycled water combined, with nearly all consisting of landscape irrigation. Approximately 1.2 AF of recycled water was used for dual plumbing, and none was used for dust control or soil compaction. Table 6-5 summarizes the amount of recycled water being used in 2020 for each direct beneficial use, as well as projected future volumes and uses. Approximately 1,300 AF of projected recycled water demands are estimated to replace current potable landscape demands. The actual and projected recycled water uses do not include recycled water system losses. The 2020 projected estimates of recycled water use from the City's 2015 UWMP is compared to the actual 2020 recycled water use in Table 6-6. Optimizing the use of recycled water is an important part of a reliable long-term irrigation supply for the City, which has the political support from City Council and City Management for implementing a robust recycled water program. Chapter 14.20 of the Pleasanton Municipal Code established a policy requiring irrigation customers directly along the recycled water distribution system to convert/connect to recycled water service consistent with all applicable legal requirements, except for specific defined exemptions. The major obstacle for the remaining identified customers that have yet to convert to recycled water is the cost to upgrade existing irrigation systems to pass required regulations. The City has utilized incentives to assist customers with converting to recycled water, including setting its recycled water rate at 90 percent of its potable water rate (see Chapter 9). This financial incentive will likely provide adequate stimulus to encourage irrigation customers within the recycled water service area to use recycled water over potable water. Additionally, the connection fee to service new irrigation accounts is lower for recycled water than potable water. All irrigation meters (i.e., meters that service strictly landscape irrigation) servicing City -owned properties within the recycled water distribution area have been converted to recycled water. The City's ongoing actions to encourage the use of recycled water are summarized in Table 6-7. WEST YOST 6-21 City of Pleasanton 2020 Urban Water Management Plan May 2021
