The ZWAR does not install private drinking water connections to the public canalisation himself. Since these connections must correspond to the generally approved technology standards, the execution of constructions is subject to a certification of pipelines or canal construction companies. Regional resident companies, which have proven records of such certification, are registered with the ZWAR. Under the following links you get the companiy names and contact infrmation:
Please choose one or several of these companies and ask and compare quotations. Confirm the quotation of your choice in writing. For filing applications, the companies will offer help and submit them to the ZWAR. However, you must sign the application forms personally.
For the installation of drinking water private connections, the ZWAR concludes contracts with the company you have chosen. The full amount of the costs is passed on to you, plus a handling charge by means of tax notification (public law tax notification).
The executed construction of the water connection is to be announced in writing. Here you can find the form which is to be signed by you as the client and by the company carrying out the constructions. Acceptance of the drinking water private connection cannot take place without prior hygienic analysis through an independent institution. The construction companies are aware of this and instruct this. Please check if this service is inclusive of the services quoted. After installation of the water meter equipment by the ZWAR, the water system can be operated.
Please note that also house installation may be constructed only by authorized installation companies.
