About Us

The Upper Thompson Sanitation District was formed in 1971 to provide wastewater treatment service to the areas surrounding the Town of Estes Park and to improve the water quality of the Big Thompson River.

The plant and collection lines were built with Federal, State and local funding at a cost of $5,327,667.00. The plant was brought on-line in 1976, providing service to areas of the Estes Valley which were previously without adequate sewage treatment.

The District is staffed with 16 permanent employees:four administrative personnel, five on the lines crew and seven operators at the plant. State of Colorado Wastewater Certification is required for all lines and plant personnel.

The District policies and operations are overseen by a Board of Directors elected by the voters within the District.

The Upper Thompson Sanitation District Treatment Facility (or Plant) is a Tertiary (or three stage), Advanced Treatment Facility. When the plant was constructed, it contained several innovative technologies, making it one of most advanced treatment facilities in the world. Today it is still one of the finest plants in a rapidly advancing field of wastewater treatment. This facility was built to handle a flow of 1.5 Million Gallons per Day (MGD), and a peak hydraulic flow of 3.75 MGD. This corresponds to an equivalent population of 15,000 people. Over 99% of the solids and pollutants in the wastewater are removed and disposed of. In the fall of 2000, Phase 1 (of a 3 Phase expansion) was completed, raising the plant capacity to 2.0 MGD by adding a new secondary clarifier.
