body
BACKGROUND INFORMATION:
The Surface Water Treatment Facility (“SWTF”) provides approximately fifty percent (50%) of Lodi’s annual drinking water supply. Twenty-eight (28) municipal groundwater wells throughout the City provide the remaining 50% of the supply, eight of which are fitted with diesel-powered generators.
When commissioned in 2012, the SWTF included a back-up generator that would provide minimal power to operate the SCADA system and other ancillary functions of the facility. At that time, it was decided not to include a back-up generator sized to process and deliver drinking water to the distribution system. This decision was based on the unlikely event of a long-term power interruption.
While the City’s electrical system is safe and reliable, the State’s power grid has grown increasingly unreliable due to statewide demand and natural disasters such as wildfires. The increased frequency of Public Safety Power Shut Offs (PSPS) imposed by PG&E, coupled with additional power demands increases the risk of long-term power outages. Because of the increased concern that long-term outages outside of the City’s control will become more frequent, there is an increased need for an upgraded generator that will provide 100% back-up power at the SWTF.
This project includes the installation and system integration of a new 800KW generator for the SWTF (Exhibit A) to allow the plant to be fully operational during power outages. On February 19, 2003, the City Council approved Olympian (supplied by Caterpillar) as the standard for standby electric generator equipment in the City. The specifications reflect that Council action. The standardization of these generators remains relevant to maintain consistency in the operation and maintenance of critical infrastructure.
The plans and specifications are on file in the Public Works office located at 221 W. Pine St., Lodi, CA, 95240 and can be accessed upon request during normal business hours. The planned bid opening date is August 28, 2024. The construction project estimate is $500,000.
STRATEGIC VISION:
5D. Infrastructure: Ensure capacity for future growth.
FISCAL IMPACT:
This project will have a minimal impact on annual operation and maintenance costs, and will help maintain essential facility operations during power outages.
FUNDING AVAILABLE:
This project will be funded through the Water Capital Outlay Fund. $500,000 is currently budgeted in Fiscal Year 2024-2025.
