Excavation underway for washwater recovery building

There’s always something big going on at the Rinconada plant during Reliability Project construction and over the next few weeks, one of its biggest is going to start taking shape.

The water district has started excavating to prepare the location for a 9,600-square feet washwater recovery facility, a key component in the treatment process. It will be where the upper sludge drying basins are currently located, about 300-feet south of Granada Way and 600-feet east of More Avenue.

Washwater recovery facilities take water used to backwash filters and recycles it back through the treatment process. The new Washwater Recovery Facility will better contain and make easier washwater recovery and distribution.

To build the facility, the water district will need to haul away roughly 17,650 cubic yards of dirt from within the plant to the Dumbarton Quarry in Fremont. That means more trucks along the approved route. The increase was noticeable this week and will be less the week of April 11 as the work shifts to soil nail installation and cement work. Excavation will ramp up again for a week beginning Monday, April 18. The entire hauling will take about two months, but will be less than what took place last fall during the start of the construction project. 

The district expects about 75 trucks each day. General trucking hours are between 8 a.m. and 5 p.m. Haul trucks with excavated soil are restricted to 9 a.m. to 4 p.m. In both cases, trucks will not run between the dismissal times of 2:30 p.m. and 3:30 p.m. for Rolling Hills Middle School out of consideration for the amount of students leaving the school.

Please contact the district’s neighborhood liaison Tony Mercado at 408-426-1039 or via email at tmercado@valleywater.org to report excessive speeding or other concerns so that the water district can take appropriate action.
