GILCREST WWTP - Advanced Wastewater Treatment in Gilcrest, Colorado

GILCREST WWTP is a municipal wastewater treatment plant located in Gilcrest, Colorado, a small town in Weld County. The facility serves a population of approximately 1,600 residents, providing advanced treatment to protect local water quality. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 741.94 thousand cubic meters per year and an annual discharge volume of 306.62 thousand cubic meters, the plant operates well within its capacity. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Colorado Department of Public Health and Environment. The treated effluent is discharged into a local water body that ultimately drains into the South Platte River, a major tributary of the Platte River system. This river network supports diverse aquatic life and provides water for agricultural and municipal use downstream. The plant's advanced treatment helps reduce nutrient loading, protecting the ecological health of the South Platte Basin.

The plant discharges into a local water body that flows into the South Platte River, which then joins the Platte River and eventually the Missouri River. This watershed supports a variety of fish species and is an important migratory corridor for birds. The advanced treatment at GILCREST WWTP helps minimize nutrient pollution, which is critical for preventing algal blooms and maintaining oxygen levels in the river system.
