It therefore seems obvious that an alternative and intelligent use of the water resource is as important as the energy transition. Indeed, the market for innovative energy-saving solutions or intelligent solutions for passive houses is booming. On the other hand – except in the industrial sector – the concepts of water saving or water treatment for public buildings, apartment buildings or private households are of less interest, especially for investors.
Start-ups specializing in the development of new water-related technologies quickly discover the difficulty of conquering this market when they venture there and want to develop a profitable business model. Large industrial companies have largely monopolized the collective management of water and their motivation for systemic change is rather slowed down by business models, admittedly functional, but often obsolete. Investors, too, continue to focus primarily on high-tech services, where new ideas can come to fruition with relatively little manpower and in a short period of time. Cleantech start-ups, on the other hand, need a lot of time, R & amp; D projects and especially capital to industrialize their solutions. It sometimes takes years to develop a technology, test it, bring it into the regulatory framework and then industrialize it to bring it to market. It is therefore particularly important for young companies in the water sector to show, through reference projects, that the market is keen to experiment and subsequently benefit from their innovations. Funding is at the heart of the problem.
