Boxelder Sanitation District is a Special District (Quasi-Municipal), a political subdivision of the State of Colorado established under Title 32, Article 4 of the State Statutes, for the purpose of providing sanitary sewer service. The District was organized in 1965 and is governed by a five member board of directors.

The District serves portions of Fort Collins, Windsor, Severance, Timnath and unincorporated areas of Larimer and Weld Counties. 

Our District maintains 100 miles of sewer lines and treats approximately 1,940,000 gallons of wastewater every day. Each home in our District uses about 100 gallons of water per day, while business and commercial sites may use more. Once water enters the drain, it becomes wastewater and must be treated to meet certain standards before being returned to the Boxelder Creek and the Poudre River.

Our treatment plant has been recognized by the Environmental Protection Agency for its ability to treat wastewater, helping to keep our rivers and streams free from contaminants. It is our responsibility to clean wastewater and return it safely to the environment. Please see our wastewater treatment page for more information.
