Project Summary

The RVSD collection system relies on pump stations and associated force mains to transport wastewater to the Central Marin Sanitation Agency (CMSA) treatment plant. 

The Larkspur Pump Station 14 Improvements include replacing the generator for standby power, replacing a VFD, replacing pump/level controls with a new PLC-based control system, reviewing the odor control system for additional capacity, roof repair, and replacement of an internal concrete platform for safety.

Backup electrical system improvements to address reliability issues of generator power at PS14 (Larkspur) and PS24 (650 S. Eliseo near Via Holon) and PS25 (1350 S. Eliseo at Bon Air).   Roofing and platform improvements at PS 14.  Lot line adjustment at PS14 in cooperation with the Larkspur Corte Madera School District (Hall Middle School).

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.

These upgrades to old or outdated system infrastructure will enhance local wastewater system reliability and efficiency.
