The facility serves a small population of approximately 1,260 residents, reflecting the scale of a rural community treatment system. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment as the minimum standard for municipal wastewater plants. The plant has a designed capacity of 681.37 volume units and discharges a similar volume of treated effluent. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent from Buffalo WWTP ultimately reaches the Mississippi River via local tributaries, contributing to the overall water quality management of the Mississippi River basin.

The plant's discharge is regulated to protect this vital waterway and its associated ecosystems.

Buffalo WWTP discharges into the Mississippi River basin, which drains into the Gulf of Mexico. The Mississippi River is a critical freshwater resource supporting diverse aquatic species and providing habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf of Mexico, an ecologically sensitive zone.
