Wainscott Project


The Suffolk County Water Authority (SCWA) has entered into an agreement with the Town of East Hampton to connect properties in Wainscott to the SCWA public water system as part of the Wainscott water supply project to address contamination of private wells in the Wainscott area.

Approximately 45,000 feet of water main will be installed in the impacted area, located south of the East Hampton Airport, making it the largest water main project SCWA has undertaken in nearly 20 years. The project area includes more than 500 homes.

The Suffolk County Department of Health Services confirmed the presence of pefluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in more than 150 private wells in the impacted area, with a small number of private wells showing detections over the health advisory level of 70 parts per trillion.

There are two components to the Wainscott project. The first is the installation of water mains and service taps in the street to bring water to the edge of the property. The second is the installation of a private service line across the property to the home or business and the disconnection of the private well.

Water main will be installed on all roads where none currently exist by SCWA’s water main contractor, Roadwork Construction Corp. The property owner has the option of either hiring a private plumber to install a service line or to have it installed by another SCWA contractor, Asplundh Construction. Once installed, the service line belongs to the property owner who is responsible for its maintenance.
