Suffolk CoSCSD18Heart IndPkSTP is a municipal wastewater treatment plant located in the Hauppauge Industrial Park within the Town of Smithtown, Suffolk County, New York. The plant serves a population of approximately 1,500 people and operates as part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale must meet effluent limits to protect water quality. The designed capacity is 6,245.91 units, indicating the plant has reserve capacity for future growth. The plant's treated effluent is discharged into local waterways that eventually drain to the Atlantic Ocean. Being within 10 km of the coast, the discharge must comply with stringent regulations to protect sensitive coastal ecosystems. The facility plays a key role in safeguarding the region's water resources and supporting the local environment.

The plant discharges into the local watershed, which flows into Long Island Sound and ultimately the Atlantic Ocean. The coastal environment supports diverse marine life, including fish and shellfish, and is an important ecological zone. The plant's proximity to the coast necessitates careful management of nutrients and pollutants to prevent eutrophication and protect downstream habitats.
