Genesee Water and San District Wastewater Treatment Plant, Jefferson County, Colorado

Genesee Water and San District is a wastewater treatment facility located in Jefferson County, Colorado, United States. The plant serves a population of approximately 4,010 residents in the Genesee area, providing advanced treatment to protect local water quality. The plant operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,028.32 million liters per year and an actual discharge volume of 969.07 million liters per year, the facility has ample capacity to handle current flows. As a US plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Colorado Department of Public Health and Environment. The treated effluent is discharged into local waterways that ultimately drain into the South Platte River basin. This river system flows through the Denver metropolitan area and eventually joins the Platte River in Nebraska. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the semi-arid Colorado Front Range region.

The plant's discharge enters tributaries of the South Platte River, which flows through the Denver metro area and across the Great Plains before joining the Platte River in Nebraska. The South Platte basin supports diverse aquatic life, including several fish species, and provides water for agriculture, recreation, and municipal use. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing algal blooms and maintaining dissolved oxygen levels in the downstream river system.
