Flow Control Valve Stations

During the fall of 2010, the Department of Public Works, along with Redwood Engineering Company, conducted a subsurface site investigation to support the design of future flow control valve vaults to be located at each of the five existing water supply turnout locations throughout town.  Brisbane and GVMID obtain their supply of water from the San Francisco Public Utility Commission (SFPUC) at the “turnouts”.  The design of the vaults was completed this summer after multiple staff reviews by engineers from California Department of Public Health and the SFPUC.   

Funded in part through a U.S. EPA grant received by the City in 2006, the flow control vaults will provide the equipment necessary for the City to better control the water it receives from the SFPUC.  Currently, the City manages the flow of its water from SFPUC by manually operating valves.  After the project is completed, City engineers will be able to remotely monitor and control the flow of water entering the City’s water distribution system at each of the five water turnout locations.   Inside the concrete vaults, new automated valves and control instrumentation will be installed that will operate remotely by sensing changes in flow and pressure of the source water and will communicate with City engineers though the SCADA (Supervisory Control and Data Acquisition) computer at City Hall.   

So there you have it.  Technology's playing a part by the SCADA computer being able to "talk" to the valves from a remote location (City Hall), by closing and opening them, and the valves will be able to "talk back" to the SCADA computer by passing along data which the engineers at City Hall will use to closely monitor water flow and pressure.

The first two locations where flow control vaults will be installed are at 100 San Francisco St at the entrance to Old Quarry Road and at 1105 San Bruno Ave. near the intersection with Bayshore Blvd.  

The work is scheduled to begin at 1105 San Bruno Ave. on Wednesday, August 31st.  The work is scheduled to begin at 100 San Francisco St. on Tuesday, September 6th.  

Please exercise caution when you see orange cones and/or flagmen helping to direct traffic around the construction area near the intersection of San Bruno Ave. and Bayshore Blvd.  

Installation of flow control vault stations will continue over the next 2 months at the following three additional locations in Brisbane:

• 11 San Bruno Ave. (@ San Francisco Ave.)
• 200 Main St.
• 100 North Hill Dr.

  Thank you for your patience as work on this very important project commences!
