Indian Lake T STP and On Site Sys - Town of Indian Lake, New York Wastewater Treatment Plant

Indian Lake T STP and On Site Sys is a municipal wastewater treatment facility located in the Town of Indian Lake, Hamilton County, New York. The plant serves a small population of 565 residents, reflecting the rural character of the Adirondack region. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 529.96 units, and it currently treats an average daily flow of 242.27 units, indicating operational headroom. As a small facility, it is subject to state-level NPDES permitting administered by the New York State Department of Environmental Conservation. The treated effluent is discharged into a local water body within the Hudson River watershed, which ultimately drains to the Atlantic Ocean. The plant plays a key role in protecting the region's sensitive aquatic ecosystems, including headwater streams that support cold-water fisheries and recreational water quality in the Adirondack Park.

The plant discharges into a receiving water body within the upper Hudson River basin, a region known for its pristine headwaters and diverse aquatic life. The watershed drains through the Hudson River to New York Harbor and the Atlantic Ocean. The surrounding Adirondack ecosystem includes sensitive cold-water habitats for brook trout and other native species, making effective wastewater treatment critical to maintaining water quality and ecological integrity.
