Document Description
The proposed San Geronimo Treatment Plant (SGTP) Permanent Emergency Generator Project (Project) will include the installation of a limited number of new small facilities and structures adjacent to an existing tank and other infrastructure at the San Geronimo Water Treatment Plant. The Project will include the installation of two (2) 1.5 megawatt generators, two 10,000 gallon above ground storage tanks, leak detection equipment, a spill containment berm, and an upgraded gravel access road to facilitate maintenance and operational activities. When completed, the Project will ensure continued supply of safe drinking water to MMWD's 190,000 customers during periods of power loss associated with the PG&E's Public Safety Power Shutoff (PSPS) events and other unforeseen power outages. Installation of the emergency generator and associated facilities will require minor excavation and construction on a small portion of the SGTP site.
