Ground water infiltration can also be lowered by cutoff techniques such as sheet loading. High dewatering costs have actually faded the profit margins on far too numerous tasks.

This option should constantly be thought about when evaluating the possibility of dewatering. Certainly the alternative is only feasible if gravity can run the water to reduced ground.
