Crowder State Park Wastewater Treatment Plant, Grundy County, Missouri

Crowder State Park wastewater treatment plant is located in Grundy County, Missouri, United States, serving a small population of 16 people. The facility operates as part of the state park's infrastructure, treating wastewater generated by campground visitors and park facilities. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for most municipal wastewater facilities. With a designed capacity of 7.57 thousand cubic meters per year, the plant matches its current discharge volume, indicating efficient operation for its small scale. The treated effluent is discharged into local waterways that drain into the Grand River basin, eventually reaching the Missouri River and then the Mississippi River. This small plant plays a role in protecting the local watershed and downstream aquatic ecosystems from untreated waste.

The plant discharges into streams within the Grand River watershed, which flows into the Missouri River and ultimately the Mississippi River. The surrounding area is primarily rural and agricultural, so the plant helps prevent nutrient pollution and pathogen contamination in local water bodies that support diverse aquatic life and recreational uses.
