Check out the latest news about construction of one of the largest public works projects in the Sacramento region’s history—the EchoWater Project. This monumental Regional San project is a multi-year effort to implement State-required upgrades to our wastewater treatment plant in Elk Grove in order to remove ammonia from our discharge and add filtration and enhanced disinfection processes.
For more than 30 years, Regional San has carefully managed the 2,650 acres surrounding our treatment plant to create high-quality habitat for hundreds of wildlife species, as well as buffer our operations from surrounding neighbors.
