The Northwest Lakewood Sanitation District was organized in 1954 and approved by the District Court of Jefferson County on July 26, 1954, under what is now known as the Special District Act.

The Northwest Lakewood Sanitation District encompasses an area of approximately six (6) square miles within Lakewood, Wheat Ridge, and unincorporated Jefferson County. The District is generally located between 38th Avenue (north side), 10th Avenue (south side), Kipling Street (east side) and I-70 (west side). There are properties outside of these general boundaries, including some property west of I-70, south of 6th Avenue and east of Kipling (see map).

Serving both residential and commercial properties, the District’s sanitary sewer collection system includes over 65 miles of sewer pipeline and over 1,400 manholes. The District contains approximately 4,000 homes and 500 commercial or multi-dwelling properties, serving in excess of 20,000 people daily. The District has an approximate peak day flow of 2.2 million gallons of wastewater per day.

The District maintained its own treatment plant until September 2004. At that time the plant was shut down and all wastewater treatment was transferred to Metro Water Recovery. The District also assigns one director to the Metro Water Recovery Board of Directors, who work to support its mission to protect the region’s health and environment by cleaning water and recovering resources.
