Marathon City Wastewater Treatment Plant at Night

Marathon City Wastewater Treatment Plant in Marathon City, Wisconsin, with treatment basins, service buildings, and a large storage tank illuminated during overnight operations. The municipal facility processes the village’s wastewater through a series of treatment stages designed to remove solids, organic matter, and other pollutants before treated effluent is released under state and federal permit requirements. Plants of this type operate continuously to manage residential and commercial sewage and to protect downstream water quality.
