Paradigms changes related to the use of natural resources and the formulation of proposals aimed the sustainable development lead to an irreversible path which not only creates awareness, but also generates a responsibility on the society to make the rational use of the water. In a number of countries, are constituted commissions and councils to address the issue of sustainable development. In addition, legislations are created and regulated, new products are thought to eliminate or minimize the environmental impact, products are thought considering their life cycle. Sustainable products have been increasingly valued by the market, making up requirements in a wide range of civil engineering projects. The AeroEcológico Sanitary system consists of using the same principle / system used in aircraft sanitary system, whose system basically uses a vacuum pump to capture the waste deposited there. It is a technology extracted from aviation that aims at the preservation of water resources, as it does not make excessive use of water. The principle of operation is that when discharge is triggered, the air from the external medium (1 atm) invades the pipe (under vacuum) in order to equalize the pressures between the two environments. This pressure difference generates an inflow of approximately 80 liters of air into the pipeline at speeds above 600 kilometers per hour (km / h), carrying the waste. Only 1 liter (or less) of water is used to clean the sanitary, which represents a saving of 10 times in water consumption, compared to the (traditional) gravitational system. A rainwater harvesting system can be incorporated into the project, which will help the consumer to reduce water consumption expenditures for the disposal of sanitary waste by 100%. (AU)
