24 Potable Water Distribution System. The City’s distribution system currently consists of approximately 330 miles of pipelines, 14 pump stations, and 21 water storage tanks. The City’s distribution system has 16 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 Dublin San Ramon Services District (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 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 approximately 7percent of the City's annual potable demands with recycled water. The City currently has a total of 98 permitted recycled water use sites, consisting of 151 metered service connections serviced with recycled water. Management Brief biographies of key members of City staff involved in management of the Water System are set forth below: Public Works Director – Siew-Chin Yeong.
