23 Nov Environmental Friendly Cofferdam
Dewatering projects come in all different shapes and sizes and there is an option to make them enviromentally friendly, but the one thing that remains the same is water. Each of us has an impact on our local water supplies, both in terms of water quality and the amount of water we use in times of drought. During a construction project there are many variables that can contaminate the water such as heavy equipment leaks, diesel and oil, paint, solvents, cleaners and other harmful chemicals; and construction debris. This is why constructing these projects in a dry dewatered area can help minimize the environmental impact.
Following the environmental guidelines set forth by The Clean Water Act Detroit Tarp’s water inflated dam system has minimal impact on the environment, whether it’s used in construction as a dam and dewatering solution, as a flood fighting structure or as a water storage system.
As a flood fighting solution the system can easily be deployed without the need to bring in huge quantities of sand or other non-native material. Disturbance to surrounding areas is very minimal. Removal of the system is complete with no residual material to be cleaned up and hauled out. In construction applications requiring a cofferdam, the system does not penetrate the subsurface and results in no long term issues unlike sheet piling where the bottom pile sections often break and are left behind in the waterway creating permanent faults in the river or stream-bed. http://detroittarp.com
