River dykes

Regular severe flooding at the start of the twentieth century resulted in rivers and streams of the Emscher-Lippe region being dammed up with dykes. Precipitation and wastewater were to be transported quickly and safely away in the concrete-lined wastewater channels. Pumping stations prevented water from collecting and accumulating in nearby low-lying areas. Without a great number of pumps and dykes along the Emscher and Lippe, the majority of the cities would still often be underwater today.

High safety standards apply to the load-bearing capacities of the dykes: They must be capable of withstanding floods that statistically only recur every 200 years. Due to the typical V cross-section, our lined waterways can hold large volumes of water in the event of high waters. This makes it all the more important that the Dykes are stable. The use of coal washery tailings, a by-product of mining, has proven particularly effective here. The material is both cost-effective and particularly suitable for dyke construction.
