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.
