Upper Monument Creek Regional WWTP | Monument, Colorado Wastewater Treatment

Upper Monument Creek Regional WWTP is a municipal wastewater treatment facility located in Monument, El Paso County, Colorado. It serves a population of around 27,000 people in the growing Colorado Front Range region. The plant operates under the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For a facility serving this population size, secondary treatment is typically mandated, with additional nutrient removal requirements in sensitive watersheds. Treated effluent from the plant likely discharges to Monument Creek, a tributary of the Arkansas River, which flows through the Great Plains to the Mississippi River and ultimately the Gulf of Mexico. The plant plays a key role in protecting local water quality and downstream ecosystems.

The plant's discharge enters Monument Creek, which flows into the Arkansas River, a major tributary of the Mississippi River system. The Arkansas River supports diverse aquatic life and is used for irrigation and recreation. Downstream, the Mississippi River carries nutrients to the Gulf of Mexico, where excess nitrogen and phosphorus contribute to seasonal hypoxic zones. The plant's treatment processes help mitigate nutrient loading in this context.
