SW Umwelttechnik Stoiser & Wolschner AG

SW Umwelttechnik Stoiser & Wolschner AG

The family company SW Umwelttechnik Stoiser & Wolschner AG was founded in Klagenfurt in 1910 and has been listed at the Vienna Stock Exchange since 1997. The company has been developing and producing precast concrete elements used in infrastructure construction above and below ground level – for over 105 years in Austria, 25 years in Hungary and 15 years in Romania. SW pipes connect households with water treatment systems instead of letting wastewater seep into the ground. SW structural elements provide people rooves over their heads and turn mere spaces into work places. SW water protection systems collect and filter wastewater, thus, protecting the surrounding environment. We improve a location’s attractiveness and quality of life in Austria and CEE with projects spanning from underground and road construction to structural engineering and residential building.

SW Umwelttechnik markets cost-effective, environmentally sound water and wastewater, infrastructure and renewable energy products. The locations of our sites enable us to meet demand for environmental solutions locally and with great flexibility.

Sustainability has been a priority for SW Umwelttechnik for decades due to the nature of our products. In this spirit our company is committed to contributing to the environmentally and socially sound development of economies, which is currently possible in particular because of EU expansion into Central and Eastern Europe.

With our services and products we are able to contribute to the development of infrastructure and the protection of the environment in Central and South Eastern European countries in a sustainable and economical manner.

  • We make the most of the growth opportunities in the EU accession countries of Central and Eastern Europe
  • We are one of the top 3 players in high-yield market segments
  • We concentrate on the sectors of water conservation, infrastructure and project engineering

We believe that the best decisions are reached by well informed employees who are empowered to work independently, and we therefore delegate responsibility. Our staff are given a stake in the Company's profits, so as to align their interests with those of the business. Because of this, they also regularly receive all relevant information on the Company's targets and current business developments.

We offer water conservation, engineering and infrastructure products and services in Central & Eastern Europe, and aim to be market leader in these segments.

We aim to solve our clients' problems to the best of our ability, and to build up long-term business relationships with them.

Our goal is quality leadership in our industry, and we produce optimised products for our clients.

We continuously improve our products in collaboration with our clients, public agencies and scientific institutions, so as to maintain our technological advantage.

We regularly provide our financiers (shareholders and banks) with up-to-date information that gives a true and fair view of our business performance.

In all our market segments, we seek to manufacture products that will benefit the environment, and we work to produce them to increasingly strict environmental standards.

We would like to set an example for others, and always keep our word. We reach our commercial targets as a socially and environmentally responsible neighbour.

We intend to continue to deliver POA and cash flow that are above average for our industry.
