Wastewater System

The Basham Simms Wastewater Facility was built in 2002 and upgraded for advanced nutrient removal and increased capacity to 1.5 mgd in 2010. The average daily wastewater flow is 575,000 gallons per day. There are about 35 miles of sewer lines including 2.5 miles of force mains, four town maintained pump stations and four private pump stations. The treatment process includes coarse screening, grit removal, primary clarification, fine screening, enhanced nutrient removal in a membrane biological reactor, and ultraviolet radiation disinfection.
