In 1986 the District constructed the original 0.5 million gallons per day (MGD) lagoon facility on 25 acres at our current location (6501 WCR 26). The District initiated an engineering study in 1999 to begin developing a long-range plan for wastewater treatment. At that time it was decided that expanding the lagoons to a capacity of 1.5 MGD would consume most of the original 25-acre plant site and make the future transition to a mechanical system very difficult and expensive. The decision was made to transition immediately to a mechanical plant.

The current 3.0 MGD facility was constructed on a 40 acre site and placed into operation in March 2002. In an average day the facility receives 2.85 MGD of raw wastewater, which is treated to meet limitations established by the U.S. Environmental Protection Agency and Colorado Department of Public Health and Environment before being discharged to Oxbow Lake and on to the St. Vrain Creek.

St. Vrain Sanitation District is currently working to build an expanded plant at 6 MGD to serve the growing communities of the district. This will be completed in late 2012 and will provide up to date and leading technology in treating waste.

The treatment plant facility is fully staffed with knowledgeable and trained individuals who understand the proper treatment of the sewage that each customer deposits in the system. The dedicated staff ensures that the water returned to the creek meets all state and federal environmental standards.
