Water is the lifespring on the earth, the material basis of the human being's survival and the social economic development, and the important guarantee of sustainable development. With population expansion and economic high-speed growth, the situation of water shortage in most urban and rural regions, which are characterized as natural resourse type, water quality type and water management type, due to lack of water resourses, improper distribution, inorder utilization and bad environmental protection etc, become serious gradually. So water saving admits of no delay. Thereby establishing water-saving society is necessary choice of planning people and nature which develop harmoniously as a whole, constructing affluent society completely and actualizing sustainable development stratagem.

Then establish math model by the analytical hierarchy process and the fuzzy analysis method to evaluate the degree of water-saving society construction. Another main task of water-saving society construction is regime construction, including administrative law, economical and technological measure and so on, which accelerate the development of water-saving society.Taicang City is a typical area south of Changjiang River, which economy is developed and natural resources are abundant, and its geographical place is superior. Evaluating water-saving society construction of Taicang City can represent the level of the developed district. So it has better significance to lead water-saving society construction in the whole country based on describing natural environment, social economy, water resource and water environment, the paper discusses emphatically the development of district social economy, water demand forecast and the analysis of balance between supply and demand of water resourse in current and future condition. At the same time through investigating the level and quantity of water use that can analyze the potentiality of water-saving in Taicang City. It also analyzes synthetically the aim, task and social security system of water-saving society construction in Taicang City. At last, the paper applies the math model to evaluate water-saving society construction of Taicang City in current and future condition, and both conclusions are middle level, but the trend of development is ascending. It indicates that the degree of Chinese water-saving society construction is underway phase at large. There is much more potentiality of water-saving.
