SW Umwelttechnik Stoiser & Wolschner AG was founded as a family business in Klagenfurt in 1910 and is listed on the Vienna Stock Exchange since 1997. The company develops and produces precast concrete products for the expansion and building of infrastructure above and below the ground – and has been doing so for more than 105 years in Austria, 25 years in Hungary and 15 years in Romania.
SW Pipes connect households to sewage facilities instead of letting waste water seep into the ground. SW Structural Engineering Parts give shelter to people and create work places. SW Water Protection Systems collect and filter wastewater and thereby protect the surrounding environment. This is how SW Umwelttechnik improves the quality of life and strengthens the attractiveness of Austria and the CEE region as a business location.
