Hayduk Engineering prides itself in being at the forefront of innovative design in wastewater. Having specialized in wastewater engineering for over 35 years, our technical expertise and reputation in this field is well recognized on Long Island. Hayduk Engineering has provided engineering design and construction administration for numerous private and public projects, including sewer collection systems, pumping stations and force mains,  wastewater treatment facilities of all sizes,  and new and emerging innovative and alternative wastewater treatment technologies. Hayduk Engineering has designed treatment plants using many types of processes, including conventional activated sludge, extended aeration, aerated lagoons, rotating biological contactors (RBC), sequencing batch reactors (SBR), trickling filters, modified ludzack-ettinger (MLE), biologically engineered single sludge treatment (BESST), membrane biological reactors (MBR), and ecological wastewater treatment (EWT) systems.

We have managed many projects that require troubleshooting, forensic investigations, and studies of existing systems. Having decades of experience, our team has the hands-on knowledge and understanding of the design, installation, and operation of the various types of systems and wastewater treatment processes that exist today.

Hayduk Engineering also holds the title and responsibility as Engineer of Record for numerous wastewater treatment facilities in Suffolk County, NY.

Representative Project: College Woods Sewers, Central Islip, NY

College Woods Pumping Station, Central Islip, NY

At the time, College Woods was the largest community development project in the United States. It offered affordable and attractive housing to those pursuing the dream of home ownership. The project transformed a blighted area in the Carleton Park area of Central Islip into a prideful community and established covenants and restrictions to help maintain its legacy and promise well into the future. The project included the installation of a sewer collection system, road reconstruction, upgrades to the storm drainage system, and various other roadway improvements.

Hayduk Engineering was responsible for the engineering design and construction supervision of the sewer collection system, pumping station and force main connection into Suffolk County Sewer District #3 – Southwest. The sewer collection system consists of 20,500 LF of 10” and 8” diameter PVC trunk and lateral sewers, 118 4’ Ø sanitary manholes, a submersible pumping station, valve chamber, control building, emergency generator, and 1,100 LF of 6” diameter PVC force main piping connecting into the Southwest Sewer District.

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