The joint company is the municipalities' response to ever higher quality requirements and increasing cost pressure in the supply of drinking water.
The company's governing bodies are the Management Board, the Supervisory Board and the Shareholders' Meeting. The Supervisory Board consists of a total of 13 members. Four members are delegated by the municipality of Bestwig, four members by the town of Meschede, four members by the town of Olsberg and one member from the workforce.
