Wasserleitungsverband Nördliches Burgenland

WLV-Logo Wasserleitungsverband Nördliches Burgenland

The Wasserleitungsverband Nördliches Burgenland is an association of local authorities which was founded in 1956. It is composed of 66 municipalities located in three districts (Eisenstadt, Mattersburg and Neusiedl).  Its main task is to sufficiently supply members with high quality water.

Via 63,000 taps, the WLV supplies drinking water for approximately 160,000 people and up to 200,000 people during the summer months. To accomplish this, 15,3 Million cubic metres of water are pumped out of our fourty-five wells and springs.  In order to deliver the water we need, 2,855 kilometres of water pipelines have been installed and maintained. Each of our customers consumes an average of 208 litres of water per day. Our most important water resource is situated in Neudörfl and consists of two wells which can provide 800 litres per second of the best quality drinking water.

The WLV not only provides drinking water, however.  It is also very much involved in issues such as ground water protection, prevention of ground water pollution and promoting an intact environment for the well-functioning supply of drinking water.

A total of almost 160 people are employed at both locations--the headquarters in Eisenstadt and the district office in Neusiedl am See.

In 2007 the sub-company WLV GmbH was established.
