The technology used by WeCo allows the transformation of the wastewater coming from the toilets, into treated water for flushing. The toilet flush is integrated in a closed water circuit and does not need connection to the sewerage. WeCo toilets even produce a surplus of clean water, which could, for example, be used for watering the surrounding area. They also produced bio-treated sludge that can be reused for agriculture in a circular economy spirit. The local treatment and recycling enable WeCo toilets to be off-grid and therefore mobile from a place to another. This innovative patented and internationally awarded technology is specifically adapted for emerging cities where there is no water, no sewerage, no sanitation plant and a strong growing urbanization leading to social, health and environmental problems. Our aim is to have a large positive environmental and social impact, by scaling with and industrial and international approach.
