Operations at ground water level are required in cases where building work takes place near ground water. In contrast to traditional technologies like trenches, earth basins or absorbing wells, with the patented jet-suction infiltration process hw-DSI® the water remains underground and must not be brought to the surface. The procedure for the targeted infiltration of ground water, from the firm Hölscher Wasserbau GmbH, of Haren, Germany, thus represents a cost-efficient, safe and effective option in comparison to conventional infiltration methods, and offers both economic and ecological advantages.
