The ZWAR is in the fortunate position of being able to exclusively process drinking water from its own ground water resources. Qualitatively as well as quantitatively, our ground water offers favorable conditions. In order to satisfy demands, it is neither necessary to get additional water supplies from the mainland, nor does surface water need to be used, or sea water desalinated. The exceptional water quality enables us to process without taking technically complicated measures or even adding chemical agents to complete the  process. The water is released by means of oxidation and conventional gravel filtration from iron and manganese components and is delivered to the net.

The stocks of water are not always where they are needed. The towns and spa resorts need the most water, and they have this need primarily in summer. Technically speaking, this means that the capacities and the dimensioning of facilities must be organised to cope with seasonal demands. In winter, the demand decreases drastically and more so due to the fact that the number of Rügen?s inhabitants is, unfortunately, still falling. The supply facilities and processing plants are not used to capacity and a possible contamination caused by stagnant water in the distribution network needs to be prevented. This situation requires optimum operating arrangements.

Today, the association operates 31 water works. In order to secure stable supplies, groups of different water work facilities have been connected. Thus, possible breakdowns or other occurrences can be dealt with effectively. These networks can result in the mixture of water from different water works. If you want to find out about water quality or water hardness, you should bare this in mind.

Concerning the water hardness, e.g., when installing washing machines or dishwashers, we advise you to use the top value of water hardness within the connected water work facilities. For inquiries, please contact our water technologist, Mr. Trefflich, under 03838/8004-57 or e-mail trefflichzwar.de.
