Developed by 4 SME of Rennes which SETUR in the cluster Ecorigine, Hydrocity ® is a patented concept of innovative and integrated management of non-potable water, adaptable to different scales of a serviced sector (macro-block, block). It is based on the implementation of the methods and techniques of "short cycles" in a short loop logic:
- Rainwater from roofs inaccessible;
- Storm surface water flow;
Hydrocity ® helps reduce the pressure on the water resources of viable without waterproofing, manage runoff at the source, to recover energy and preserve important areas for biodiversity in urban areas. The treated water is returned in part to the natural environment, and part stored and distributed to accommodation and the services (water supply and washing machine hunts).
