Our History

The St. Vrain Sanitation District is a quasi-municipal corporation and a political subdivision of the State of Colorado. In 1986, the District was created to serve the area near the intersection of I-25 and State Highway 119, commonly referred to as Del Camino, and the surrounding areas.

Since our initial beginnings, the St. Vrain Sanitation District has grown from serving a few local residents and businesses into a District serving over 15,000 business and residential customer accounts.  We provide service to the City of Dacono, the towns of Firestone and Frederick, portions of Mead, and areas of Weld County that are within our boundaries.  Those businesses and industries along the I-25 corridor, Highway 52 and 119, as well as some along Highway 66, are currently served by the St. Vrain Sanitation District.  Our District stretches from roughly the Boulder/Weld County Line on the west to the Platte River on the east and from Weld County Road 40 on the north to Weld County Road 6 on the south. Thanks to the vision and leadership of the Board of Directors, we continue to meet the needs of sanitary sewer service for many in the region. 

St. Vrain Sanitation District now encompasses over 140 square miles of land.  With continued growth in the region, we will continue to see an expanding population and customer base.  The current board is committed to providing quality customer service, regional service, excellent wastewater treatment facilities, maintenance of our collection system, and discharge regulation through our Pretreatment program.  The construction of our plant upgrades was completed in May 2023 following a two-year, nearly 37 million-dollar capital improvement project.  The new plant discharges to St. Vrain Creek and consistently meets the regulatory requirements in the NPDES (National Pollutant Discharge Elimination System) permit. The new plant is currently rated at 6 MGD (Million Gallons per Day) and 15,200 pounds of BOD (Biochemical Oxygen Demand). The plant operates at 56% of its organic capacity.  As the District continues to see development and growth, the plant is designed for expansion to keep pace with the increased demand.  The plant is located on the north side of Weld County Road 26 between Weld County Roads 13 and 15.
