Meridian MD Wastewater Treatment Plant, Parker, Colorado

Meridian MD is a wastewater treatment plant located in Parker, Colorado, within Douglas County. Serving a population of approximately 35,225, the facility is part of the municipal infrastructure that manages wastewater from this growing suburban community near Denver. As a US-based plant serving a medium-sized agglomeration, Meridian MD operates under the regulatory framework of the Clean Water Act, administered by the EPA and likely permitted through the Colorado Department of Public Health and Environment. Plants of this scale typically employ secondary or advanced treatment processes to meet National Pollutant Discharge Elimination System (NPDES) permit requirements. The treated effluent from Meridian MD ultimately drains into the South Platte River watershed, which flows through Colorado and Nebraska before joining the Platte River. This river system supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment at this facility helps protect water quality in the South Platte Basin.

The plant discharges into the South Platte River watershed, a major tributary of the Platte River that flows through the Front Range urban corridor. This river system supports fish species such as rainbow trout and channel catfish, and provides critical habitat for migratory birds along the Central Flyway. Downstream, the Platte River feeds into the Missouri River, ultimately reaching the Mississippi River and the Gulf of Mexico. Maintaining high water quality in this basin is essential for ecological health and downstream water users.
