This project consists of rehabilitating a regional domestic wastewater pump station including replacing crucial existing equipment and constructing other various site improvements. Equipment replacement includes new raw sewage pumps, modifying existing motorized valve actuators, installing new motorized valves and valve actuators, new piping both within and outside the station, new electrical switchgear, MCC panel and Variable Frequency Drives (VFD’s) as well as a new back up diesel generator to power the station in the event of loss of PG&E power. Site improvements include structural modifications for seismic safety, additional yard piping for pumping flexibility, fencing and paving. The project also includes some mechanical improvements at two other remote pump stations.
- This is a 3-story pump station retrofit project. (2 stories are below ground level)
- There is a "Larry Line" on site, which was named after the Maintenance Mechanic who identified the need form more pumping flexibility.
- This project needed to be completed in phases, in order to maintain continuous operation.
- Lone pump stations can be sensitive to power failure. A new diesel generator was installed in its own enclosure.
- This retrofit includes close coupled motors and pumps vs. traditional motor shaft coupling connections.
