Project Info

Title
El Centro Generating Station (ECGS) Wastewater Mitigation Project
Description
The project consists of improvements to the IID El Centro Generating Station (ECGS) wastewater facilities to achieve new and more stringent limitations for the concentration of specific pollutants that are discharged in its waste stream to receive a renewed NPDES permit from the RWQCB. The project includes equipment to minimize the cooling tower blowdown by increasing the cycles of concentration (COC), a water softening reactor, a repurposed evaporation pond, an ultrafiltration (UF) and a reverse osmosis (RO) system. Three new evaporation ponds are proposed on the site of the existing Bonanza Building. These ponds will cover 9 acres and will have an interior slope of 6:1 and an exterior berm slope of 4:1. An 18-inch overflow pipe will connect the ponds.
