Featured Project: Wincoram Commons Pumping Station and Force Main, Coram NY

Wincoram Commons Pumping Station and Force MainThis 150 unit affordable housing rental community also incorporates 15,000 square feet of retail space on the ground floor of several of its buildings in a village type setting. The owner is a partnership of a private Rochester, NY developer and the Community Development Corporation of Long Island.

Hayduk Engineering was originally retained to design the STP modifications necessary for the project to connect to another existing local, privately owned SBR treatment facility. During the design phase, we determined that structural deficiencies in the existing STP hampered this proposal, and we initiated discussions with Suffolk County, ultimately receiving approval for connection to the SCSD-11, Selden sanitary system. The onsite pumping station and off-site, 4,700 LF force main were designed by, and construction inspected by HELLC, and have gone into operation during the summer of 2015.

The project includes connection to a Suffolk County DPW run Sewer District and two directional drillings of the force main under a State Highway (Route 25) and a private road, as well as open cut installations in easements as well as public roads.

The project was approved by the Suffolk County Sewer Agency (SCSA) and was reviewed, approved and inspected by/under SCDPW oversight.
