The drinking water in South Zealand is the hardest in Denmark. This means that the citizens of the area more often experience dripping water pipes, calcium on the bathroom tiles and in water boilers etc. than the citizens in other parts of Denmark. The impact of hard water hits heavily on energy use and associated maintenance costs.
Therefore, The Danish water-supply company HOFOR has decided to establish water-softening facilities in seven plants and modernize tree large, regional water treatment plants to reduce the calcium. This solution benefits both the consumers and the environment.
