The plant serves a small community of about 568 people, providing essential sanitation services to the area. As a secondary treatment plant, it meets the standard level of treatment required for most US municipal facilities under the Clean Water Act. The plant has a designed capacity of 302.83 volume units and currently discharges approximately 143.85 volume units of treated effluent. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The facility operates under the regulatory framework of the US Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES), which sets discharge limits to protect water quality. The treated effluent from Morrisville WWTP is discharged into local streams that are part of the Osage River basin, which ultimately flows into the Missouri River and then the Mississippi River. This watershed supports diverse aquatic life and provides water resources for communities downstream. The plant's location inland and its small population served contribute to a lower environmental risk profile compared to larger coastal facilities.

The Morrisville WWTP discharges into local waterways within the Osage River basin, which drains into the Missouri River and eventually the Mississippi River. This watershed supports a variety of fish and wildlife species, including game fish and migratory birds. The plant's inland location and small discharge volume help minimize its impact on downstream ecosystems, though nutrient loading from treated effluent can still affect local water quality.
