Dublin San Ramon Services District to move sewer lift station in anticipation of street widening

The board of directors for the Dublin San Ramon Services District (DSRSD) recently approved funds to replace and relocate a sewer lift station on westbound Dublin Boulevard. DSRSD is moving the sewer lift station before the City of Dublin begins widening the road between Dublin Court and Sierra Court later in the year. The district does not anticipate closing busy Dublin Boulevard at any time during the project.

DSRSD is moving the lift station so staff can continue to access it without blocking traffic once the road is widened. The district’s board of directors have awarded a $987,500 contract to JMB Construction (South San Francisco, CA) to replace and relocate the sewer lift station on westbound Dublin Boulevard. In addition, the DSRSD Board awarded a $238,492 task order to Carollo Engineers (Walnut Creek, CA) to manage the construction project, conduct inspections, and review materials and equipment for conformance with specifications.

The underground sewer lift station is located under a sidewalk near Murco Plaza, across from the Dublin Sports Grounds. Any work that requires a lane closure will be done at night, Sunday through Thursday. At least one lane of traffic in each direction will always be open, even at night.

The sewer lift station raises the elevation of sewage by 17 feet so it can continue to flow by gravity to the DSRSD Regional Wastewater Treatment Facility in Pleasanton. This avoids excessively deep trenches for downstream pipes, which would have been more costly to construct and maintain. This is the only lift station in the district’s system; elsewhere in the district sewage flows downhill entirely by gravity to the treatment plant.

The lift station is an unseen but vital part of DSRSD’s sanitary sewer system. DSRSD is moving the lift station so staff can continue to access it without blocking traffic once the road is widened. To minimize disruption to the public, the district has arranged for the city’s contractor to move water meters, fire hydrants, and other DSRSD water and sewer facilities later, when the road is being widened. DSRSD will reimburse the city for the cost of this work through an intergovernmental reciprocal services agreement.

The district anticipates starting the project in late April and to complete the project this fall. DSRSD provides both potable and recycled water to some 173,000 people in Dublin and the Dougherty Valley area of San Ramon.  Additionally, DSRSD services includes wastewater collection and treatment to Dublin and south San Ramon, as well as wastewater treatment to the city of Pleasanton by contract.
