Treatment plant expansion for smart economic development
Covering 1,400 acres and over 220 buildings, the Hauppauge Industrial Park is the second largest industrial park on the east coast. Despite being home to 1,300 businesses employing more than 55,000 people, only a portion of the parcels within the park were connected to sewers. The two existing treatment facilities in the district had a combined flow capacity of 450,000 gallons per day.
H2M designed an expansion of the Suffolk Business Center treatment plant, which allowed an increase in capacity to 1.65 million gallons per day. The expansion will allow 250 additional properties to be connected to sewers. The expansion plan also includes construction of nine additional miles of gravity sewer; three new sewage pumping stations with three miles of force main piping; and conversion of a smaller WWTP into a wastewater pumping station.
The benefits of the project are many. Placing all of the businesses in the park on sewers will remove hundreds of septic systems, making a major positive impact on Long Island groundwater quality. The project also allows for expansion of the industrial properties both horizontally and vertically beyond their current footprint, allowing for two- and three-story buildings to be developed. All around, the project is a win-win, allowing for growth and economic development in Hauppauge while protecting the environment.
The $44.8 million project was completed within the client’s budget, and has since won over a once skeptical community. It has garnered positive feedback from area residents, as well as local politicians, and won a 2015 Silver Engineering Excellence Award in the Waste and Storm Water category from the American Council of Engineering Companies of New York (ACEC NY).
