Mechanical construction services to increase the capacity of the Newtown Creek Wastewater Treatment Plant without disrupting operations.
In addition to refurbishing four sedimentation tanks, Heritage Mechanical Services provided industrial piping services including the installation of approximately 850 feet of 96" diameter, 1/2"-wall, stainless steel aeration, flocculation and channel air piping. Due to the plant's tight layout, the company used special lifts and rigging equipment to raise pipes, ranging in diameter from 66 to 96 inches, into the air and over 40-foot high operational tanks. Heritage teams then assembled the piping in the air and lowered it carefully into position within the facility, a process that required extensive preliminary planning as well as advanced rigging expertise.
The Newtown Creek Wastewater Treatment plant is the largest of New York's 14 wastewater treatment plants. It serves approximately one-million residents in a drainage area of more than 25 square miles fed by 180 miles of sewer lines. The plant began operation in 1967 with a capacity of 310 million gallons per day during dry weather. Upgrade work began in 1998 to replace outmoded, environmentally unsound facilities. The plant's capacity will eventually rise to 700 million gallons per day during wet weather storms. By 2045, the city anticipates that the upgraded plant will serve 1.33 million residents. Those involved organized the refurbishment's design and construction in phases over a 10-year period, during which the plant will remain fully operational.
