Challenge
At Bluecon we took the challenge to make the transition needed to provide the more than 80% of rural areas in the world who don't have acces to any wastewater treatment or sanitation. The Bluecon method is really the key to bring solutions for all the areas where it is too cold, hot, far away, too low in occupancy or with too much fluctuation in wastewater volume. We believe that together with the traditional centralized biological treatement plants and our partners and competitors, we can clean up all the water in the world!
