WEST CHESTER, Ohio, June 29, 2015 /PRNewswire/ -- Contech Engineered Solutions supplied a new stormwater detention system to Liberty Park, an elevated public park under construction in the new World Trade Center in New York City.
Liberty Park will have a capacity of 750 people and will sit 25 feet above Liberty Street overlooking the National September 11 Memorial & Museum. The park will feature a 20 foot high "living wall" and the St. Nicholas Church, destroyed in the September 11 attacks, will be rebuilt in the park.
A stormwater detention system was needed to meet NYC Department of Environmental Protection stormwater regulations. These regulations call for the reduction of the quantity of stormwater runoff leaving a site by temporarily storing the runoff that exceeds the site's allowable discharge rate, and releasing it slowly over time.
Since the park will sit on the roof of the Vehicular Security Center, it is imperative the detention system is watertight. Contech consulted with engineers at the Port Authority of New York & New Jersey who specified a stormwater detention system made from 197 linear feet of DuroMaxx® Steel Reinforced Polyethylene (SRPE) that will provide approximately 2,500 cubic feet of stormwater storage. DuroMaxx achieves a level of watertight joint performance that sets it apart from conventional pipe products. Contech also consulted with the contractor, Oliveira Contracting Inc. to construct a custom hold down system to prevent the tanks from floating while being backfilled with cellular concrete.
"This was not a typical detention system. The watertight requirements and the hold down system required special consideration," said Tom Slabe, President of Contech's Treatment Segment. "Everyone at Contech is proud our products are being used to rebuild such an important site."
Construction of the park is expected to be completed in early 2017.
