With daunting compliance deadlines on the horizon, Sacramento Regional County Sanitation District, also known as Regional San, is at the peak of the largest and most ambitious project in its history. After nearly a decade of planning, engineering, testing and construction, the nearly $2-billion EchoWater project aims to meet a 2010 stringent treatment requirement issued by California and local authorities. They have called for cleaner discharge into the Sacramento River by 2023 from the Sacramento Regional Wastewater Treatment Plant in Elk Grove, Calif.
With 21 projects, the EchoWater program’s largest components are now under construction and, despite complexities, the project remains on track to complete major work in 2022. The construction area is approximately 480 acres on a 3,550-acre site (including existing facilities and buffer zones).
