- Document Description
- The State Water Resources Control Board (State Water Board) is a Responsible Agency for the Project. The State Water Board’s Clean Water State Revolving Fund (SRF) Program is financing the Project. The purpose of the Project is to enable the City of Richmond (City) to replace aging and unreliable infrastructure, comply with future discharge regulations, and upgrade or replace non-functioning or obsolete treatment processes with efficient, adaptable, and reliable systems. Additionally, improvements for the aeration system will reduce health and safety impacts from aerosols created by the existing mixers. Work at the WWTP will include implementation of the Project, which will upgrade the grit removal system, aeration system, and secondary clarifier. Upgrades at the grit removal system would include construction of a new screening and vortex grit removal system to replace the non-functioning existing gravity grit chambers. Construction activities include demolition of the existing grit basin structure and construction of a new screening/grit structure that would include a fine screening, two (2) vortex grit basins, and new Parshall flumes for flow measurement.
