Dorrance WWTP - Secondary Wastewater Treatment in Dorrance, Kansas

Dorrance WWTP is a municipal wastewater treatment facility located in Dorrance, Russell County, Kansas, United States. The plant serves a small population of 205 residents, reflecting the rural character of the community. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits to protect water quality. The designed capacity of 151.42 thousand cubic meters per year indicates the plant is sized for the local population, with current discharge at about half that volume. The treated effluent is discharged into a local water body that ultimately drains into the Saline River basin, part of the larger Kansas River watershed. This region supports agricultural activities and provides habitat for aquatic species. Proper treatment helps maintain water quality in downstream ecosystems.

The treated effluent from Dorrance WWTP enters a local stream that flows into the Saline River, a tributary of the Smoky Hill River, which joins the Kansas River and eventually the Missouri River. This watershed supports diverse aquatic life and is used for irrigation and recreation. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this agriculturally influenced region.
