The Wells Sanitary District, a quasi municipal corporation, was formed in 1970 for the purpose of providing a safe and effective system of wastewater disposal for portions of the Town of Wells. Although the District was formed in 1970, the District's wastewater treatment system did not become operational until 1980.

The District’s wastewater treatment facility is a modern secondary treatment plant, with a permitted capacity of 2.0 million gallons per day. The wastewater collection system presently includes ten remote pump stations and nearly forty miles of sewer line. The District’s treatment system operates in an activated sludge mode. The dewatered sludge is converted into a soil additive at a licensed facility located in Plymouth, Maine.

The day-to-day administration, operation and maintenance of the wastewater facility is conducted by the District’s seven employees under the direction of the Superintendent.

The main area presently serviced by the District is along and east of Route One. Portions of certain roads west of Route One also have the availability of public sewers.

The District is governed by a five-member Board of Trustees. The Trustees are elected at the Town of Wells annual meeting for three-year staggered terms. The Board of Trustees holds regular meetings once a month, with special meetings being scheduled when the Board believes conditions warrant more consideration. All meetings of the Board are public and the time, date and location of the meetings are posted. Each meeting follows a written agenda with minutes taken to record actions and decisions made by the Board of Trustees.

The District’s normal business hours are 7:30 a.m. to 4:00 p.m. Monday through Friday. Other hours are available by appointments made through the Superintendent's office.
