Clarus Fusion - A sustainable on-site wastewater recycling solution for people without access to a municipal sewer

This solution makes dignified sanitation possible for every individual, no matter the location. By re-using the treated effluent on site for non-potable applications (toilet flushing, irrigation, etc.), this solution can significantly reduce potable water consumption. By making use of this solution, it is possible to develop in areas where there is no infrastructure. This is a perfect solution for bringing sanitation to all schools, reducing potable water demand in the urban edge (domestic, commercial and industrial) and bringing new opportunities through the re-use of the treated effluent. This also speaks directly to Green Building, sustainable living and is the perfect answer for the "living building" model. The operating cost of this solution is much less than alternatives, which makes it one of the most affordable and most sustainable alternative water sources available today.
