The Sacramento region can expect to see big changes related to how wastewater is treated and reused with the completion of Regional San’s $1.7 billion, decade-long expansion. Named the EchoWater Project, the immense upgrade was completed in spring 2023—on schedule and under budget. The result is a safe and reliable supply of treated water for discharge to the Sacramento River, which will also be used for recycled water purposes—like irrigating local agriculture and supporting habitat conservation land.
The expanded tertiary treatment facility is now the second largest treatment plant of its kind in the nation, and the expansion project was among the largest public works projects in the Sacramento region’s history. Regional San treats an average of 135 million gallons of wastewater each day from 1.6 million people throughout Sacramento County and West Sacramento.
