Remediation of water

This procedure, also called hydraulic redevelopment, is based on the extraction of contaminated ground water from the water-saturated ground zone by means of appropriately dimensioned well and pump systems.

By continually extracting the ground water, the normal ground-water flow direction in the adjacent area of the redevelopment well is influenced in such a way, that the ground water forms a depression funnel and water flows to the well from all sides.

Apart from eliminating water-soluble contaminants, this effectively prevents a further increase of the damage to the ground water.

Especially in inner-city areas, the preservation of lakes and thus the maintenance of the microclimatic conditions are utterly important for keeping the ecological balance.

Special equipment like suction-/rinsing dredges or dredge grapple loaders remove sediment and silt from the water, and subsequently process the extracted material on land. This procedure also can be applied to remove contaminated sediment build-up from the waters.

In both cases, the dredged and recycled material preferably is re-used. We put much emphasis on an environmentally harmless and justifiable implementation of such measures.
This can be realised by limiting the dredging to the water only.

One of our services in our range of activities is the recycling of the material handled by us. The dredged sediment and leachate is dehydrated by each individual fraction and reused in composting plants, as covering material for the recultivation of landfills or for agricultural use.
