Perry Park WWTP - Colorado Wastewater Treatment Plant Serving 3,100 Residents

Perry Park WWTP is a municipal wastewater treatment facility located in Perry Park, Douglas County, Colorado, serving a population of about 3,100. The plant is situated in a semi-arid region at the eastern edge of the Rocky Mountains, where water resources are carefully managed. As a small-to-medium agglomeration in the United States, the plant is subject to the Clean Water Act and is expected to meet secondary treatment standards under the National Pollutant Discharge Elimination System (NPDES). The Colorado Department of Public Health and Environment issues permits that set effluent limits to protect water quality in the South Platte River basin. The plant's treated effluent likely discharges to a tributary of the South Platte River, which flows northeast through Colorado and Nebraska before joining the Platte River. This river system supports agricultural irrigation, municipal water supplies, and diverse aquatic habitats, making effective treatment essential for downstream communities and ecosystems.

The plant's discharge enters the South Platte River watershed, which drains the eastern slope of the Rocky Mountains. The river flows through Denver and across the Great Plains, ultimately joining the Platte River in Nebraska. This basin supports critical habitat for fish species such as the plains killifish and provides water for agriculture and urban use. Effective wastewater treatment helps maintain water quality in this semi-arid region where water scarcity is a growing concern.
