Eco-Friendly, Water Saving Sanitation System

AbstractSanitation facility is among the main living requirements of mankind. It should be more hygienic and easy. Presently, many existing sanitation systems extensively depended on pipe borne water. On the contrary, some parts of the world experiences water scarcity and that has led to un-hygiene sanitation systems. In terms of eco efficiency, even the hygienic sanitation systems have more opportunity to improve. Inefficient water consumption and none usage of nutrients available in excreta in a useful manner are main culprits. Since nutrients available in excreta are not returned to soil breaks the nutrient cycle, end up with less fertile soil which could not directly use for agricultural purposes. Therefore, this research focuses on design and developing an eco-friendly sanitation system, on ancient which minimize pipe borne fresh water usage for sanitation while facilitating nutrients mixing to soil in order to enhance soils fertility based eco-friendly filtering mechanism. The proposed system has three focused areas: water saving option, eco-friendly digestion method with a business model. The new design reduces water consumption with the assistance of manually operated mechanical suction system. An energy free digestion mechanism handles the solid part of excreta. Bio degradable cheap or freely available material is used as filtration media and replaceable blocks have been designed for easiness to operate the new method. Since proposed system facilitate re-usage of black water and digested excreta on biodegradable media as fertilizer while closing the loop of the cycle of nutrients, proposed system can be branded as eco-friendly sanitation system
