Our goal is to ensure the availability and sustainable management of water wells for all. Started as a scientific work at the Montanuniversität in Leoben, the environmentally friendly ultrasonic technology for the cleaning and regeneration of water wells has been fundamentally redeveloped. By 2030, the efficiency of water use in all sectors is to be significantly increased and a sustainable extraction and supply of fresh water is to be ensured. This goal for sustainable development was the cornerstone of the research that has now produced the spin-off Ultrawell GmbH in Vienna as an Innovation Leader. The system developed for daily use in regular cleaning and regeneration of drinking water wells relies on the well-known ecologically safe cleaning of water wells by means of highly effective ultrasound.
