D.C. Water and Sewer Authority
The Blue Plains Advanced Wastewater Treatment Plant is the largest plant in the world. It has the capacity to treat 370 million gallons of sewage a day.
Each day the D.C. Water and Sewage Authority processes nearly 400 million gallons of raw sewage from D.C., and parts of Maryland and Virginia. Rob Sachs tours the Blue Plains Advanced Wastewater Treatment Plant in Southwest D.C. to see what it takes to clean the water and make it suitable for discharge into the Potomac River.
