The key actor in water management and environmental protection in Lodz is the City of Lodz Office. An important role is played by the Municipal Company of Water Supply and Sewage Systems, which produces and provides drinking water to the city and delivers sewage to the WWTP. The city’s 2,000 km of water-pipe network and 1,600 km of sewers are maintained by the Lodz Infrastructure Company. Both companies are supervised by the City Council, which establishes the framework for their functioning and makes strategic decisions.
