The Maratschbach hydropower project was realised by the E-Werk Pflersch energy cooperative in collaboration with the EWS engineering office under the direction of Dr. Ing. Markus Zössmayr. The project involves the construction of a diversion power plant that draws its drive water from two small creeks inside the Pflersch valley.
In order to transport the water to the plant, it was necessary to use pipes that could withstand the high water pressures. Therefore, it was decided to use the TRM Pipe System, which is known for its proven quality, durability and simple installation. These key factors played a significant role, as the laying work took place at an altitude of over 1,500 meters above sea level. The 1.8 km long pipeline, consisting of TRM DN 400 pipes with VRS®-T joints, could be installed fast and easily thanks to its innovative system.
One of the biggest challenges of this project was the steep, rocky terrain in which the installation work took place. The solution was to use pipes with ZMU coating, which are resistant even to large underground materials of up to 100 mm.
The project was successfully completed in June 2023 thanks to the excellent collaboration between the engineering firm EWS, the construction company Gebrüder Oberprantacher GmbH, the energy cooperative E-Werk Pflersch and TRM. This enabled the realisation of a sustainable energy project with the aim of not only strengthening the region's energy supply, but also helping to protect the environment.
Safe water supply.
