KEENESBURG STP - Secondary Wastewater Treatment Plant in Keenesburg, Colorado

KEENESBURG STP is a municipal wastewater treatment plant located in Keenesburg, Colorado, United States. The facility serves a population of approximately 1,150 residents and operates under secondary treatment standards, which is the minimum required by the U.S. Clean Water Act for municipal wastewater treatment. As a secondary treatment plant, KEENESBURG STP utilizes biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 378.54 megaliters per year and currently discharges 227.13 megaliters per year, indicating operational capacity below its design limit. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The plant discharges treated effluent into a local water body that is part of the South Platte River basin. The South Platte River flows through Colorado and Nebraska before joining the Platte River, which ultimately drains into the Missouri River and then the Mississippi River. The plant's operations help protect downstream aquatic ecosystems and water quality in the region.

KEENESBURG STP discharges into a tributary of the South Platte River, which flows through the semi-arid plains of eastern Colorado. The South Platte River supports diverse aquatic life and provides water for irrigation and municipal use downstream. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting the river's ecological health and downstream water quality.
