Consulting for surface water

Gravel and sand quarrying for the construction industry plays a major economic role in numerous areas throughout Germany, primarily in the North German Lowlands or in the floodplain areas of major rivers. It is common practice for deposits to be extracted below groundwater level, leading to the formation of quarry lakes.

WESSLING checks the quality of the new waters that have formed during and after the end of the quarrying work. Amongst other aspects, our experts base their evaluation on the guideline "Erstbewertung von Baggerseen nach trophischen Kriterien" (Initial assessment of quarry lakes according to trophic criteria) of the German Working Group on water issues of the Federal States and the Federal Government (LAWA). They also help you to implement the European Water Framework Directive specifications. These come into play for quarry lakes measuring over 50 hectares.

WESSLING ensures that the new uses of the waters (such as sport or drinking water production) and relevant nature protection aspects are subject to constant control.
