The Wastewater Treatment Division operates a wastewater treatment facility that accepts sanitary sewage from St. George, Ivins, Santa Clara, and Washington City. The treatment plant has a design capacity of approximately 17 million gallons per day (mgd), and currently treats an average of 9.5 mgd. The plant utilizes an oxidation ditch / extended aeration process that uses physical and biological processes to treat the sewage. There is a 97 to 98% removal rate of contaminates in the treatment process. 

 

The wastewater treatment plant also has the support of a State certified laboratory that is accredited through a national program called NELAP. The lab performs testing for plant process requirements, required Utah Pollution Discharge Elimination System testing, pretreatment testing, and drinking water testing.
