24 substances (PFAS). Since that time, the City has been purchasing 100 percent of its water supply through the Tri-Valley’s water wholesaler, Zone 7 Water Agency. The well sites remain assets of the City. Potable Water Distribution System. The City’s distribution system currently consists of approximately 327 miles of pipelines and 22,369 water service connections. There are 14 pump stations, 22 water storage reservoirs, and one hydropneumatic tank in the distribution system. The City service area has 14 different pressure zones. Emergency Interties. The City currently has two existing pipeline interties with the Dublin San Ramon Services District (“DSRSD”) and one pipeline intertie with the City of Livermore for rapid emergency response. These interties are strictly for emergency conditions, such as a major pipeline break, supply contamination, or interruption of deliveries due to earthquake, flood, or other disasters. Recycled Water Facilities. The City does not own a wastewater treatment facility. The majority of the City’s wastewater is treated by DSRSD, which owns and operates the Regional Water Treatment Facility, which also treats wastewater from Dublin and the southern portion of San Ramon. The facility includes conventional secondary treatment facilities, as well as tertiary and advanced recycled water treatment facilities. In addition, wastewater produced from the southeastern portion of the City, referred to as Ruby Hill, is treated by the City of Livermore, which also owns and operates a wastewater treatment facility which produces tertiary treated recycled water. The City purchases recycled water from both DSRSD and the City of Livermore; with the Livermore supplied recycled water restricted to landscaping in the eastern portion of Pleasanton. In 2016, the City completed its Recycled Water Project (the “RW Project”) to serve landscapes irrigated with potable water, which included the construction of approximately 51,500 lineal feet (LF) of new recycled water pipeline, ranging in diameter from 6 inches to 20 inches, and repurposing approximately 22,400 LF of existing potable pipeline into the recycled water system. The RW Project was funded through a Clean Water State Revolving Fund Program loan and Proposition 1 Program Grant Agreement with the State Water Resources Control Board (SWRCB), with the goal of largely replacing existing potable irrigation demands along the distribution system with recycled water; thereby reducing potable water demands. To date the RW Project has reduced nearly 10 percent of the City's annual potable demands with recycled water. The City currently has a total of 94 properties (out of a possible 100), consisting of 149 metered service connections (out of a possible 158) serviced with recycled water.
