Lochbuie Lagoon Wastewater Treatment Plant, Colorado

Lochbuie Lagoon is a municipal wastewater treatment facility located at 700 County Road 39 in Lochbuie, Colorado, within Weld County. The plant serves a population of approximately 1,251 residents, providing secondary treatment for the community's wastewater. The facility operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for all point source discharges. For a plant of this scale, secondary treatment is the standard requirement, ensuring that organic matter and suspended solids are adequately reduced before discharge. The treated effluent is discharged into local waterways that ultimately drain into the South Platte River basin. This river system supports diverse aquatic life and provides water for agricultural and municipal uses downstream. The plant's location inland, far from coastal areas, reduces direct marine impact.

The plant discharges into the South Platte River watershed, which flows through Colorado and Nebraska before joining the Platte River. This basin supports irrigated agriculture, wetlands, and wildlife habitats. The river is a critical water source for the region, and maintaining effluent quality is essential to protect downstream ecosystems and drinking water supplies.
