Meadow Grove WWTP - Secondary Wastewater Treatment in Meadow Grove, Nebraska

Meadow Grove WWTP is a municipal wastewater treatment facility located along Highway 275 in Meadow Grove, Madison County, Nebraska. The plant serves a small population of 447 residents, reflecting the rural character of the community. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants of this scale. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 189.27 megaliters, and it treats an annual discharge volume of 227.13 megaliters, indicating operation near or slightly above its design capacity. The treated effluent is discharged into a local watercourse that drains into the Elkhorn River basin, ultimately reaching the Platte River and the Missouri River system. This watershed supports diverse aquatic life and provides habitat for migratory birds. The plant's inland location and small population served contribute to a lower environmental risk profile.

The plant discharges into a tributary of the Elkhorn River, which flows into the Platte River, a major tributary of the Missouri River. The Platte River system is a critical migratory corridor for sandhill cranes and other waterfowl, and supports diverse fish species. The watershed is primarily agricultural, with nutrient management being a key ecological consideration.
