Forest Hills Metropolitan District Wastewater Treatment Plant, Jefferson County, Colorado

Forest Hills Metropolitan District operates a secondary wastewater treatment plant located on South Grapevine Road in Jefferson County, Colorado. The facility serves a small population of around 350 residents, reflecting its role in a rural or suburban community within the Denver metropolitan area. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 189.27 cubic meters per day and a current discharge volume of 75.71 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local streams that ultimately flow into the South Platte River, a major tributary of the Platte River system. This river supports diverse aquatic life and provides water for agriculture and recreation in the region. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, ensuring compliance with water quality standards.

The plant discharges into the South Platte River watershed, which drains into the Platte River and eventually the Missouri River. The South Platte River is a critical water source for Colorado's Front Range, supporting ecosystems, agriculture, and urban water supplies. The river's health is sensitive to nutrient loading and other pollutants, making proper wastewater treatment essential for maintaining water quality and aquatic habitat.
