 Desert of LIWA water reservoir for the city of Abu Dhabi (Strategic Water Storage / Recovery) 
 2010-2014 (wells) 
 158 wells VEE SHAPE SCREEN baskets with gravel / installation services / etc.


 Construction of two wells in the Ecopark in the Alsatian Reichstett north of Strasbourg in France. The wells will be used for the operation of a deep geothermal energy plant (approx. 4,000 m deep). 
 2019 - 2020 
 Equipment of two wells each 64 m deep with STÜWA bridge slotted screens, slot with: 3 mm. Plain pipes in DN 1600 in stainless steel 1.4301, pipe length 12 m. Special feature: The pipes were welded at the construction site and were equipped by us with appropriate attachments, which made it possible to intercept the pipes and weld them at the construction site. 


 Kyrgyzstan - Osch, improvement of the drinking water supply 
 2014 - 2016 
 bridge slotted screens with a diameter up to 1600 mm, length 6 m, stainless steel submersible pumps 


 Geothermal system with thermal water in the spa Solec Zdrój

 Vienna - expansion of the "VIERTEL ZWEI" office & residential area as a highly modern and sustainable living area through the utilisation of geothermal energy 
 169 STÜWA GeoHeat® double U-shaped probes with an individual length of 140 metres - rolled onto a modular winch system that enormously facilitates installation; 22,000 metres of connection lines DA 40 PE 100 RC PN16 and diverse accessories 


 Flood protection at the Elz River estuary/Nonnenweier 
 Flood protection by reacting to high water phases of the Upper Rhine River. Approx. 30 metre-deep DN 2000 gripper boreholes and self-service extension, Rilsan-coated in DN 1200, were created during this project. If the Rhine reaches flooding stage, the water is conducted into retention basis, which in turn are pumped by means of 9 large wells now in existence. 


 Geothermal system – Aarau 
 3 wells for geothermal heating and cooling, 30 m deep, diameter DN1600, wire wrapped screen DN 900 stainless steel
