The project included complete reconstruction and capacity enhancement of the water treatment plant, which operates in double-line system and includes mechanical and biological treatment with front-end denitrification, nitrification with fine-bubbling aeration and vertical settlement tanks.  A new exterior two-layer tank with a volume of 10 m3 for ferric sulphate was built for chemical elimination of phosphorus. The reconstruction was carried out in the working condition of the treatment plant.

There is no doubt that application of advanced technology will have a positive impact on the quality of water in the Kamenice river, which flows into the Jizera river.
