TenCate Geosynthetics Americas is selected by Parsons Engineering of New York as the sole source to supply TenCate Geotube® containers for the dredging project on Onondaga Lake, in the State of New York. This project is the largest geotextile tube project in the US and North America.
As a result of over a century of industrial activity on the shores of Onondaga Lake, lake sediments have been contaminated with chemicals such as heavy metals, PAH's and volatile organic compounds (e.g., chlorobenzene). Due to this contamination, Onondaga Lake and related upland sites were added to the Federal Superfund National Priorities List (NPL) in 1994.TenCate Geosynthetics Americas is selected by Parsons Engineering of New York as the sole source to supply TenCate Geotube® containers for the dredging project on Onondaga Lake, in the State of New #
Dewatering and storage
The design by Parsons Engineering is to hydraulically dredge an estimated 2.1 million cubic yards of waste and pump it to a 50 acre dewatering cell through 4 miles of double-walled pipeline. Their design specifies containing and dewatering the waste in geotextile tubes stacked 30 feet in height. TenCate Geotube® containers, of various large circumferences, will be supplied to dewater the sediments. This project is scheduled to begin in the spring of 2012 and is planned to continue for 4 years. Upon completion of dredging and dewatering, TenCate Geotube® containers will be permanently stored in the capped cell.
“TenCate has been chosen for the value it brings to the project”, comments Vicki Ginter, Regional Market Manager at TenCate Geosynthetics Americas. “This includes the unique features of the TenCate Geotube® containers such as circumferential seams and mechanical geoports, a history of projects worldwide that are similar in scope and complexity, technical services including geotechnical engineering support and detailed layout drawings for the dewatering cell, quality control evidenced by its ISO 9001 certification and A2LA certified labs and the history and strength of the TenCate corporation.”
