Abstract
For traditional drainage system used in city and town, there are high consumptions of water and energy, but nutrient and water resource were lost. For widely undeveloped countries and regions, there was lack of sanition. Ecological sanitation (Ecosan) system was built based on that domestic sewage and waste material contained in it were regarded as carriers of resources and energy. It was in accordance with the current economic strategy model of sustainable development. The common features of ecosan system are simply treatment ways, nutrients recycling and water recycling. Eco-toilet is main technological unit of the narrow sense of ecosan, which was fit for low population density of areas and most of them were built in rural villages. The general sense of ecosan system is a modification to traditional drainage system used in city and town, which was fit for developed economic level and high population density of areas. In the end, the development trend of ecosan system was forecasted.
