As the first in the world, Kalundborg Forsyning now treats surface water without the use of chlorine. The new waterworks, Tissø II, is a high-tech and innovative waterworks with a focus on sustainability, where energy consumption, working environment and hygiene requirements are essential. 

Tissø II has cost DKK 90 million and will annually transport of 1.6 million cubic meters of water from Tissø and out to Kalundborg's industrial companies.

It replaces Tissø I, whose capacity is one million cubic meters a year. However, Tissø I remains backup over the next three months.
