Enterprise Wastewater Treatment Plant, Utah | Secondary Treatment Facility

The Enterprise wastewater treatment plant is located in Enterprise, Washington County, Utah, United States. It serves a population of 2,316 and operates with secondary treatment, which is the standard level required under the US Clean Water Act for municipal facilities of this scale. The plant has a designed capacity of 1,892.70 thousand cubic meters and treats an annual discharge volume of 719.23 thousand cubic meters. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids before discharging treated effluent. The treated wastewater is discharged into local waterways that drain into the Virgin River basin, which flows through southwestern Utah and eventually reaches the Colorado River. The Colorado River system supports diverse aquatic life and provides water for millions of people across the southwestern United States.

The plant discharges into the Virgin River watershed, which flows into the Colorado River system. The Colorado River is a critical water source for the arid southwestern US, supporting agriculture, urban areas, and ecosystems. The river's flow is highly managed, and treated wastewater contributes to maintaining base flows in the basin, which is important for downstream habitats and species such as the endangered Colorado pikeminnow.
