Mountain Green Wastewater Treatment Plant, Morgan County, Utah

Mountain Green wastewater treatment plant is located in Morgan County, Utah, United States. The facility serves a population of approximately 3,209 and operates with secondary treatment, which is standard for smaller communities under the US Clean Water Act. The plant's designed capacity is 3,785.40 million liters, with an annual discharge volume of 984.21 million liters. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a facility serving fewer than 10,000 people, it falls under the small community category, where compliance with effluent limits is managed through National Pollutant Discharge Elimination System (NPDES) permits issued by the Utah Department of Environmental Quality. The treated effluent from Mountain Green ultimately drains into the Weber River watershed, which flows into the Great Salt Lake. The Great Salt Lake is a critical ecosystem for migratory birds and supports unique aquatic life adapted to its saline conditions. The plant's discharge contributes to the water quality of this important regional water body.

The plant's discharge enters the Weber River basin, which flows into the Great Salt Lake, a terminal saline lake in Utah. The Great Salt Lake is a vital habitat for millions of migratory birds and supports brine shrimp and other salt-tolerant species. The lake's health depends on maintaining adequate freshwater inflows and water quality, making the plant's secondary treatment important for protecting this unique ecosystem.
