ANGOLA WWTP - Angola, Indiana Wastewater Treatment Plant

ANGOLA WWTP is a municipal wastewater treatment facility located in Angola, Steuben County, Indiana, United States. The plant serves a population of approximately 7,304 residents, classifying it as a small to medium-sized facility within the state's wastewater infrastructure. As a US-based plant, ANGOLA WWTP operates under the Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. Facilities of this scale typically employ secondary treatment as a minimum standard, with potential nutrient removal depending on local watershed requirements. The plant's treated effluent discharges into the local watershed, which is part of the Great Lakes Basin. The receiving waters ultimately drain into Lake Erie, a vital freshwater resource supporting diverse aquatic life and providing drinking water for millions. The plant plays a key role in protecting downstream water quality in this ecologically sensitive region.

ANGOLA WWTP discharges into the St. Joseph River watershed, which flows into the Maumee River and eventually Lake Erie. Lake Erie is the shallowest of the Great Lakes and is particularly susceptible to nutrient pollution, making effective wastewater treatment critical for controlling algal blooms and maintaining aquatic ecosystem health.
