MULLEN WWTP - Secondary Treatment Plant in Mullen, Nebraska

MULLEN WWTP is a municipal wastewater treatment plant located in Mullen, Hooker County, Nebraska. The facility serves a small population of 491 residents, reflecting the rural character of the area. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Nebraska Department of Environment and Energy, governs its discharge. The plant's designed capacity of 189.27 cubic meters per day matches its current discharge volume, indicating full utilization. The treated effluent is discharged into a local water body, likely a tributary of the Middle Loup River or the Dismal River, which are part of the Platte River basin. The Platte River system supports diverse aquatic life and is a critical migratory corridor for birds such as sandhill cranes. The plant's operations help protect downstream water quality in this ecologically important region.

The plant discharges into a local watercourse that drains into the Middle Loup River, a tributary of the Platte River. The Platte River basin is a vital ecosystem in the Great Plains, supporting migratory birds, fish, and other wildlife. The region's semi-arid climate makes water quality management crucial for maintaining aquatic habitats and agricultural water supplies.
