Document Description
The Napa Sanitation District proposes to replace the existing Stonecrest pump station and sewer pipeline with more reliable and higher capacity facilities to meet wet weather flows. The existing pump station will be demolished, and the new one will be built approximately 200 feet to the northeast on city-owned property. The gravity sewers that tie into the existing pump station will be diverted; approximately 1,200 feet of force main (pressurized pipeline) within Silverado Trail will be replaced, and approximately 1,140 feet of gravity sewer will be replaced along Silverado Trail (State Highway 121). The new pump station site is located on city-owned property on the west side of Silverado Trail north of Stonecrest Drive. The pipeline will be installed within Silverado Trail.
