Fiscal Year 2019/20 Force Main Appurtenance Project

Project Construction:  May - November 2020

As part of RVSD’s Capital Improvement Program, the Force Main Appurtenance Project will replace a total of eight (8) isolation and air-relief valves within the force main system as shown on the map above. These system infrastructure upgrades will enhance local wastewater system reliability and efficiency

The District selected Psomas, Inc. as the project construction manager. The project is estimated to cost $1.1 million to complete. Construction began in early-May 2020 and is anticipated to be complete by the end of November.

All RVSD projects and work activities being conducted adhere to the District’s COVID-19 Exposure Control Plan to prepare for and, mitigate against the risk of COVID-19 exposure to the District’s office staff and field workers.

Project Information and Construction Notices

Now that bird nesting season is over, work on valves in Piper Park and on South Eliseo Drive will commence. The work at the Sir Francis Drake Blvd. interchange with 101 is almost complete. Valve and vault manufacturing has been delayed due to COVID-19, which has delayed some of the work by one or two months, so that the work will be compacted at the end of the job. We believe we will still meet the target of completion by November despite these delays.
