The drinking water network in the Waldviertel region is becoming denser

EVN Wasser is building a 63-kilometer drinking water pipeline from Krems to Zwettl until the year 2025. This regional pipeline is intended to provide security in the drinking water supply of the districts of Zwettl, Gmünd and Waidhofen an der Thaya and prevent tankers from having to transport drinking water to the region again due to severe drought. This drought has been looming for decades and represents a major problem. EVN Wasser is therefore expanding its drinking water network and compressing it. The start of the new pipeline is in Brunnenfeld in the district of Krems, where large groundwater reserves are available, and it ends in Zwettel. Once the work has been completed in 2025, up to 120,000 inhabitants of the Waldviertel region will be able to enjoy a carefree supply of fresh drinking water. In order to complete the work in the best possible way, the construction was divided into three lots, with the first lot running from the Zwettl junction to the Pallweis elevated tank over a length of 24 kilometers. To ensure that the drinking water does not lose any of its quality, EVN has opted for the high-quality pipes supplied by Tiroler Rohre GmbH. A good 20 kilometers of pipes with the proven PUR Longlife coating and 4 kilometers with the innovative ZMU Austria coating, each in nominal diameters of DN400, will be installed. The Tyrolean manufacturer was also able to score points with the proven VRS-T restrained locking system to connect the pipes. The construction work is being carried out by Gebrüder Haider & Co. Hoch- und Tiefbau GmbH. Particular challenges in this project are the crossing of bodies of water, such as the Kamp River, or the work in nature reserves. Especially in nature reserves, a particularly gentle intervention in the landscape is required. EVN Wasser is a subsidiary of the Lower Austrian state energy supplier EVN.

Safe water supply.
