Project Introduction

The Front of Plant (FoP) Project consists of the design, construction, permitting, start-up, commissioning, and closeout for Receiving Lift Station (RLS), Headworks Facility, Odor Control Facilities, Influent Connector Pipe, Chemical Offload Facilities, Civil site work, Emergency Overflow pipe to storage basin and related process support systems. Work is being implemented under a Progressive Design-Build procurement process in stages.

What We Are Doing

Major construction begins in late September 2018 at SVCW’s Front of the Plant (FoP) project at 1400 Radio Road.

Preliminary work includes installing groundwater dewatering wells, ground movement sensors known as inclinometers, and pressure sensors known as piezometers. The bulk of the remaining work will focus on shaft construction. The complete shaft construction work will be completed in 2019 and includes construction of slurry wall panels and load bearing elements (both of which make up the shaft walls), excavation of both shafts and placement of large concrete slabs at the bottom of the shaft excavations.

There are two shafts that will be built at the front of the plant site. The larger of the shafts will support a Receiving Lift Station (RLS), which will pump flow from a gravity tunnel pipeline to the new headworks for the first steps in wastewater treatment. The second shaft, to be constructed adjacent to RLS shaft, will be used initially for tunnel boring machine (TBM) retrieval after tunneling is complete for the gravity pipeline and then after that to protect the RLS and gravity pipe under surge events. The shaft construction is expected to take 12 months.

What You Will See and Hear

Excavated soils from the new shafts is expected to stay at the SVCW site to minimize truck traffic in Redwood Shores. Truck traffic that does occur in relation to the construction will be directed to not exceed the 25-mph speed limit in Redwood Shores and to drive in the right-hand lanes whenever possible.

Construction noise should not be a distraction to neighbors with the possible exception to those at The Pointe, who may hear slightly louder than normal sounds due to trucks entering the site and the related construction

Front of Plant Project

The FoP project includes a 1) Receiving Lifting Station (RLS) to lift the wastewater from the gravity pipeline to the surface to be 2) screened and de-gritted by the new Headworks before flowing to the plant in 3) the new influent pipeline (IPL). Besides these three components, the FoP project is composed of site civil improvements, electrical, chemical storage, and odor control projects. Construction will last through 2022.

When Can You Expect Us?

Most work will be performed from 7 a.m. to 6 p.m. Mondays through Friday with some 12-hour days and some Saturday work when necessary.
