Case

Meeting the rising demand for water in the Danish capital

Copenhagen is one of the few capitals in which you can drink high quality water directly from the tap. As Copenhagen is growing, the city faces the very real risk of demand for water outstripping groundwater supply.

The main challenge is to maintain a high drinking water quality in the future based on groundwater supply. Due to lack of water sources within Copenhagen and local contamination of water sources immediately around the city, water has to be conducted in pipes over long distances. By adopting innovative technologies and policies, it has been possible to protect groundwater resources, limit the losses in the drinking water supply system and reduce drinking water consumption.

A combination of the 3 elements: management of water resources, groundwater protection and behaviour change, makes it possible to maintain high drinking water quality in the future based on groundwater supply.

Water cooperation
Copenhagen has a close cooperation with the nearby municipalities and water supply companies. As a result, over-exploration and waste of the water resources can be limited. Water samples are analysed every day, and the results are shared within the water cooperation.
