Measure: ContainmentStructures
Description
Construction of containment structures at sensitive locations like roads or airports. Thus raw water contaminations due to traffic accidents, leakages or similar are kept away from raw water sources for drinking water production. The aim is to ensure the constant and sufficient availability of raw water of a sufficient quality for drinking water production.
