WARROAD WWTP - Warroad, Minnesota Wastewater Treatment Plant

WARROAD WWTP is a municipal wastewater treatment facility located in Warroad, Minnesota, a city near the Canadian border in Roseau County. The plant serves a population of about 1,793 people, making it a small-scale facility under typical classification systems. Its location within 50 km of the coast suggests proximity to Lake of the Woods, a large freshwater lake that forms part of the international border. As a US-based plant, WARROAD WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. Plants of this scale in Minnesota typically employ secondary treatment or lagoon systems to meet state and federal effluent standards. The designed capacity of 1.00 million gallons per day indicates the plant's ability to handle peak flows. The treated effluent from WARROAD WWTP is discharged into the Rainy River watershed, which flows into Lake of the Woods and ultimately drains into Hudson Bay via the Nelson River system. This water body supports diverse aquatic life, including walleye and northern pike, and is an important recreational and ecological resource for the region.

WARROAD WWTP discharges into the Rainy River watershed, which flows into Lake of the Woods, a large freshwater lake spanning the US-Canada border. The lake drains northward via the Winnipeg River into Lake Winnipeg and eventually reaches Hudson Bay. This watershed supports diverse aquatic ecosystems, including important fish species such as walleye and lake sturgeon, and provides habitat for migratory waterfowl. The plant's location near the international border underscores the need for coordinated water quality management.
