Environmental Services Business
If you want to continue supplying spring-fresh drinking water tomorrow – you need to think about the entire water cycle today

Despite the fact that we take it for granted, clean water is a valuable good. And high-quality drinking water is impossible without the responsible use of natural water reserves. In our own interest – and in the interest of future generations.
Environmental services represent the second major business for EVN and are classified in three areas: water supply, thermal waste utilisation and the international project business. In Lower Austria, EVN supplies more than 500,000 residents directly or indirectly with drinking water. A strong reputation as a reliable electricity, natural gas and heat provider has led numerous communities to entrust EVN with water networks that they can no longer operate efficiently. In this area, EVN is recording steady growth. The operation of a thermal waste utilisation plant in Dürnrohr not only relies on state-of-the-art technology to make a significant contribution to waste disposal; but the heat released by the incineration process is used to supply EVN’s customers in the provincial capital of St. Pölten. Through its subsidiary WTE, EVN has realised more than 100 international projects in the areas of drinking water supply, waste water disposal and thermal waste utilisation in 18 countries across Western, Eastern and South Eastern Europe. The projects involve the design and construction of plants by EVN as well as operational management after completion if requested by the customer. Project financing is also arranged in some cases. These projects are generally commissioned by cities and communities in the above-mentioned regions, with the orders resulting from competitive international tenders.
