Ruhrverband opens the doors of the Lennestadt sewage treatment plant

Water means diversity: as drinking water, it is the No. 1 food for humans and animals, rivers and lakes are home to countless animal and plant species, it is used for recreation and leisure and, as process water, is an important raw material for industry and business.
For over 100 years, the Ruhrverband has ensured that the water bodies in the region can fulfil these diverse tasks. It operates dams, reservoirs, sewage treatment plants and rainwater treatment plants in the Ruhr catchment area in order to leave intact bodies of water for future generations.
