Abstract: Analysis and evaluation of water supply is one of the important contents in water impact assessment of building project, and is an effective measure to implement the strictest water management. Water source plan, water pipeline, reclaimed water pipeline and rationality analysis on water intake of building project need to be analyzed and evaluated. Running water, reclaimed water, groundwater and surface water were included in the water source of building project. Based on examples, the most common method was proposed to demonstrate the running water and reclaimed water including analysis of water supply guarantee and ability, current water supply, water demand within water supply area for planning years, and water quality guarantee. Thus the reliability and feasibility of the water supply for planning years were demonstrated. According to the case of the Benz factory with complex process, water rationality was analyzed from water quota, cyclic utilization rate of cooling water, water consumption rate per unit GDP and Benz factory previous water consumption, and the rationality method was analyzed.

Key words: water resource, water use rationality, water quota, analysis and evaluation of water supply, pipe net water
