The recently completed $16.5 million project upgrading Richmond’s wastewater treatment plant passed its first test last week, as it functioned as needed during the recent series of storms, according to city officials.
On Nov. 7, crews completed the project to install a new pumping station, pipeline and five million gallon storage tank on the site of the existing plant at 601 Canal Blvd. The new upgrades are aimed at preventing sewage overflows into the Bay during extreme rainfall and system backups.
Apparently the new system worked as planned during the recent storms.
“During the 48 hour period ending at 4 p.m. on Jan. 6, just under 2.6 inches of rain fell according to the rain gauge at the Richmond wastewater treatment plant,” City Manager Bill Lindsay’s weekly newsletter explained. “In the case of recent storms, an estimated seven million gallons of diluted wastewater was provided full treatment where it otherwise would have been only partially treated (or blended) prior to the existence of the WWSF. This operational capability will continue to significantly reduce the impacts of discharging partially treated (or blended) effluent to the Bay. Another benefit of this additional storage capacity is the reduction of sanitary sewer overflows (SSOs) from the wastewater collection system. Significantly, there were no SSOs identified during this recent period of wet weather.”
