Yet, huge amounts of water are lost even in places with sufficient infrastructure - a situation which Pydro GmbH is keen on alleviating. The clean-tech start-up based in Hamburg and Rostock focuses on intelligent and sustainable water networks. "Water losses worldwide average over 30 per cent with very different characteristics," said Thomas Clemens, Managing Director. While only 8 per cent of water in Germany seeps away due to outdated pipe networks, broken pipes and leaks, this figure comes to 50 per cent in Bulgaria for instance. A considerable amount of energy is needed to maintain a constant level of water pressure in the event of defective pipes. Thus, intact pipes save both water and energy. "For this reason, active water loss management is very important," Clemens stressed. But that prerequisites sufficient data.
