The Sacramento Regional County Sanitation District may have to spend more than $2 billion over the next 10 years to improve water quality.
The Central Valley Regional Water Quality Control Board on Dec. 9 directed California’s capital city to remove ammonia and other residual materials from treated water before discharging it into the Sacramento River. The city’s 28-year-old plant releases as much as 180 million gallons of water per day into the delta-feeding waterway.
