- Document Description
- The Pinole-Hercules WPCP Improvement Project EIR, which evaluated two project options for improvements to the WPCP, was certified by the City of Pinhole in July of 2010. Since that time, the cities of Pinole and Hercules have prepared preliminary designs to identify the treatment and conveyance upgrades needed at the WPCP. The preliminary designs are much like the Option 1 design, which was fully evaluated in the 2010 EIR, with a few key exceptions. The primary exception is that the previously proposed parallel 24-inch force main from the Pinole-Hercules WPCP to the Rodeo Sanitary District (RSD) Deep Water Outfall is no longer included in the project design. Rather than discharge all effluent to RSD's Deep Water Outfall, as originally proposed under Option 1, the Pinole-Hercules WPCP will now discharge up to 14 million gallons per day (MGD) of treated effluent via the Deep Water Outfall, and up to 6 MGD of treated effluent via the WPCP's Emergency Outfall only during periods when influent flows exceed 14 MGD (i.e., discharge capacity of the Deep Water Outfall). Proposed WPCP improvements include but are not limited to a new influent pump station and headworks facility south of the existing Plant structures, but within the existing developed footprint of the overall WPCP site. In addition, the project includes a new Solids Handling Facility near the existing cogeneration facility; replacement of the primary sludge pumps; expansion of existing aeration basins; and installation of two new secondary clarifiers (65 feet in diameter).
