Alden T SD 2 STP and Onsites - Advanced Wastewater Treatment in Town Line, New York

Alden T SD 2 STP and Onsites is a municipal wastewater treatment facility located in Town Line, Erie County, New York. The plant serves a small population of 135 residents, reflecting its role in a rural or suburban community within the Town of Alden. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 79.49 megaliters and an annual discharge volume of 37.85 megaliters, the facility operates well within its capacity. As a US plant, it is subject to the Clean Water Act and likely operates under an EPA NPDES permit issued by the New York State Department of Environmental Conservation, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Niagara River and Lake Erie. The plant's advanced treatment helps protect the Lake Erie watershed, which supports diverse aquatic life and provides drinking water for millions. Its inland location reduces direct marine impact, but the discharge contributes to the overall health of the Great Lakes ecosystem.

The plant discharges into tributaries of the Niagara River, which flows into Lake Erie, part of the Great Lakes system. Lake Erie is ecologically sensitive, supporting diverse fish populations and serving as a critical water resource. The advanced treatment helps minimize nutrient loading, which is important for preventing algal blooms in the lake.
