* First mast exports to a German energy company

* Water protection systems for Austrian roads

* Major orders for wastewater treatment plants in the Hungarian Mátra and a Romanian spa town

First mast exports to a German energy company

SW has negotiated a framework contract with a large German energy supply company to provide them with power masts from Hungary. The agreed monthly delivery amounts to around 1,200 masts of various models. This contract can be ascribed to the well-known quality and the excellent competitiveness of SW Umwelttechnik products.

SW is making roads safe and winterproof: orders totalling EUR 1.2 m

SW Umwelttechnik is furnishing the Citytunnel in Waidhofen with two water protection systems to purify wastewater and add to road safety. The much travelled through Ofenauer tunnel on the Tauern motorway (A 10) will also be upgraded to the newest standards of technology with an appropriate SW water protection system. A 900 m3 reinforced concrete container by SW Umwelttechnik will be installed on the A5 (North motorway). It will continuously release road wastewater and therefore prevent the maximum salt levels of nearby natural waters from being exceeded.

SW purifies CEE´s wastewater: orders totalling EUR 3.0 m

OMS, a subsidiary of the SW Group, has been commissioned as general contractor to renovate the current drinking water network in the famous spa town of Baile Tusnad in Romania. 26 km of pipelines and three sedimentation tanks with a total capacity of 1,900 m3 are to be renewed.

A further major order for OMS is the construction of a rainwater drainage system for the municipality of Bodony in the Northern Mátra mountains. A streambed reconstruction will be carried out and a concealed channel 21 km long will be installed. It will be fitted with 84 purification stand-pipes and 11 sludge traps.

SW Umwelttechnik, a family firm founded in 1910 and listed on the Viennese stock exchange since 1997, stands for sustainable management and consistent growth in Eastern and South-eastern Europe. With our innovative technology to protect the environment we provide an important contribution for the development of necessary infrastructure in Central and South-eastern Europe.
