Sewage management produces one of the worse impacts on our environment. The current technology applied is obsolete, which results in a huge public spent on installation and maintenance, with very negative consequences on the health of people and environment. The administration and the water companies try to hide these consequences, but the impacts are everyday more and more evident. This situation blocks any development of new technology that can solve the problem in a few years, changing the management, with strict control of every cubic meter of treated water and mud produced, saving an enormous quantity of money from public administration and avoiding a huge negative sanitary and environmental impact. New technologies can change the centralized depuration for decentralized depuration, avoiding the current problems, with a certificate control and saving between 80 and 90% of public inversion, and with the possibility to reuse the mud and treated water in place.
