Every day, AlexRenew treats millions of gallons of wastewater for Alexandria and parts of Fairfax County. There are two biproducts produced as part of this treatment process: clean water discharged to the Potomac River, and solids, which are organic and inorganic materials that settle out of the wastewater.

AlexRenew solids go through an extensive process for treatment. They are thickened to reduce water content, pasteurized to kill harmful pathogens, digested to reduce volume and odors, and then spun in centrifuges to remove additional water before the final product is hauled away.
