Limestone V WWTP - Town of Carrollton, New York Wastewater Treatment Plant

Limestone V WWTP is a municipal wastewater treatment facility located in the Town of Carrollton, Cattaraugus County, New York. The plant serves a small population of 675 residents and operates with a designed capacity of 757.08 thousand cubic meters per year, currently treating 302.83 thousand cubic meters annually. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring the effluent meets federal and state water quality standards before discharge. The treated effluent from Limestone V WWTP is discharged into a local water body that ultimately drains into the Allegheny River watershed. The Allegheny River flows south into Pennsylvania and joins the Ohio River, which is a major tributary to the Mississippi River system. The plant's operations help protect downstream water quality in this important regional drainage basin.

The plant discharges into a tributary of the Allegheny River, which flows through the Appalachian region and supports diverse aquatic life including smallmouth bass and various freshwater mussels. The Allegheny River watershed is ecologically significant as part of the larger Ohio River basin, providing habitat for migratory fish and maintaining water quality for downstream communities. The plant's secondary treatment helps reduce nutrient and pollutant loads to this sensitive river system.
