Dublin San Ramon Services District Commissions Dougherty Road Recycled Water Booster Main

Water resources engineers with the Dublin San Ramon Services District (DSRSD) and the City of Dublin Public Works Department energized the Dougherty Road Recycled Water Booster Main on Friday afternoon, completing a 1.8-mile purple-pipe distribution extension between Scarlett Drive and Northcreek Parkway in Dublin. Produced at the Jeffrey G. Hansen Water Recycling Plant in Pleasanton through sand filtration and ultraviolet disinfection, the tertiary-treated recycled water will now irrigate sixty-four acres of municipal sports turf, school playfields, homeowner association greenbelts, and roadway medians across central and northern Dublin. Switching those landscapes off the potable drinking water system will conserve an estimated 52 million gallons of imported Tri-Valley drinking water each year—enough to supply nearly 650 households.

To maintain steady 75-pound-per-square-inch delivery pressure across elevated hillside parks east of Dougherty Road without building a new concrete storage tank, contractors installed three variable-frequency submersible booster pumps inside an underground acoustic vault at the Camp Parks perimeter. Cellular flow meters linked to DSRSD's SCADA operations desk automatically throttle pump speeds during overnight park irrigation windows between 10:00 PM and 5:00 AM.

During the six-month trenching project, utility crews also installed four curb-side purple-pipe commercial fill hydrants along Dougherty Road and Amador Valley Boulevard. Municipal street sweepers, dust-control water trucks, and sewer-flushing vactor crews can now refill their tanks with 100 percent recycled water using a prepaid RFID access badge instead of drawing from domestic fire hydrants.

The $3.85 million pipeline and pump station upgrade was funded through a California State Water Resources Control Board Water Recycling Funding Program grant paired with DSRSD Regional Water Replacement reserves. Residents and commercial property managers can view the Tri-Valley recycled water service map and residential drought-rebate programs on the Dublin San Ramon Services District Portal.
