AlexRenew is the wastewater treatment authority for Alexandria and parts of Fairfax County. Each year, the utility processes approximately 13 billion gallons of wastewater it receives from area homes, schools, and businesses, before safely returning it to our waterways. AlexRenew also oversees RiverRenew, the largest infrastructure project in Alexandria’s history. The project will prevent millions of gallons of combined sewage from polluting our rivers and streams each year.
