TenCate Geotube selected for lake dredging project

TenCate Geosynthetics Americas has been 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.

Tencate Geotube in actionTenCate Geosynthetics Americas has been 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 thought to be 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 the related upland sites were added to the Federal Superfund National Priorities List (NPL) in 1994.

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. T

enCate Geotube containers, of various large circumferences, will be supplied to dewater the sediments. The 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."

TenCate Geosynthetics develops solutions and systems for transportation infrastructure, water management and cleaning, and environmental applications, delivered through synthetic woven, nonwoven, and knitted products. The company has production facilities in North America, Europe and Asia.  

Its parent company Royal Ten Cate (TenCate) is a multinational company which combines textile technology with related chemical processes and material technology in the development and production of functional materials with distinctive characteristics. Systems and materials from TenCate come under four areas of application: safety & protection, space & aerospace, infrastructure & the environment, and sport & recreation.
