Sedalia WSD - Projected Advanced Wastewater Treatment Plant in Sedalia, Colorado

Sedalia WSD is a projected wastewater treatment facility located in Sedalia, Douglas County, Colorado, United States. Designed to serve a population of 215, the plant will provide advanced treatment for the small community. As a projected facility, it represents planned infrastructure to meet future wastewater management needs. The plant is designed with advanced treatment capabilities, which typically includes processes beyond secondary treatment such as nutrient removal or disinfection. With a designed capacity of 49.21 volume units, the facility is sized to handle the anticipated wastewater flow from the service area. Under the US Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Colorado Department of Public Health and Environment. The plant will discharge treated effluent into a local water body, likely a tributary of the South Platte River basin, which ultimately flows into the Platte River and then the Missouri River. The advanced treatment level helps protect downstream water quality in this semi-arid region, where water resources are critical for agriculture and ecosystems.

The plant will discharge into a local stream within the South Platte River watershed, which drains into the Platte River and eventually the Missouri River. This region supports diverse aquatic life and is important for migratory birds. Advanced treatment helps minimize nutrient loading and protects downstream water quality in a water-scarce area.
