Our Services

Roxborough Water & Sanitation District (RWSD), nestled in the foothills of the Rockies in southwest Denver, is a water and wastewater utility serving over 11,000 customers.  RWSD’s number one priority is providing safe, reliable, great tasting water to the community, and efficient wastewater collection and transmission to protect public health and the environment.

About the Roxborough Water and Sanitation District (RWSD)

It is a special district which is a quasi-governmental entity with the power to tax and collect fees for water and sewer (wastewater) services. It is governed by a locally elected board of five directors, which are registered voters of Colorado and property owners in Roxborough.

About the Sewer Services

RWSD also provides the community’s sewer treatment, which is part of a regionalized agreement with the South Platte Water Renewal Partners (SPWRP). RWSD maintains and owns miles of sewer pipeline to remove and deliver the community’s sewage to the SPWRP. In addition to the community, RWSD provides wastewater services for the Lockheed-Martin Facility.

General History

The Roxborough Water & Sanitation District (RWSD) was established in 1972 to provide water, sewer and fire protection services to the Roxborough Community. In 1999, fire protection services moved from RWSD’s jurisdiction to the West Metro Fire Protection Department. Subsequently, the District’s original name, Roxborough Metropolitan District, became the Roxborough Water and Sanitation District.

In 2007, the District connected to the Littleton/Englewood Wastewater Treatment Plant (SPWRP). This regionalization eliminated the District’s 30-year-old Wastewater Treatment Plant. The SPWRP is the third largest Publicly Owned Treatment Works (POTW) in the state of Colorado. The plant receives sewage from the cities of Englewood and Littleton, as well as from 21 connector districts in the service areas of the cities. The plant is a large, advanced treatment plant required to exceed secondary treatment requirements. The design capacity is 50 million gallons per day (mgd) and is presently treating a little over half that amount.

In late 2010, the City of Aurora and the Roxborough Water & Sanitation District executed a long-term agreement in which the City remains the District’s permanent raw water supplier, in perpetuity.
