Wastewater Treatment Plant


The City of Washington operates a Biological Nutrient Removal Wastewater Treatment Plant (WWTP); that has the capacity to treat 3.65 million gallons of wastewater per day.  Domestic and Industrial Wastewater is pumped from 32 sewer lift stations into the collection system where it is conveyed to the WWTP.  This wastewater coming into the plant (influent) is then processed to remove contaminants by physical, chemical and biological processes.  The final treated products are separated into water flowing out (high-quality effluent) and Class B biosolids.  The effluent water is discharged into the Tar-Pamlico River Basin.  The Class B Biosolids are land applied to farms and used to enhance crop production.  The WWTP not only serves residents within the City, but it also services the Town of Chocowinity.
