The Water-Saving Management In University Campus

China is a big country of education, the per capita water consumption in university campus is high, there is a big water saving potential. Saving water is one of the important content to build resource-saving and environment-friendly campus. Based on engineering planning design management theory and system analysis method, this thesis makes a deep study on water-saving management theory and method which is applied to design water-saving management of Tianjin University campus.To save public-water, this thesis proposes several technical programs and demonstrates the necessary of promoting water-saving appliances and improving cleaning methods. To use infrared water-saving device if we can will minimize the waste by people. This thesis proposes a procedure of water-saving management and a method to formulate water quota which includes various methods. How to evaluate water consuming is also mentioned which includes the assessment of water records, the assessment of the pipe and water equipment, the assessment of the cleaning method in the building and the assessment of water consumption according to the quota.To save water for sale, this thesis proposes several technical programs which have to be used by the operators because of the high price of water from the aspect of technique reform. Among those programs, a water control system for IC cards is focused on. From the aspect of system reform, this thesis proposes the meaning of gradational water price in the water saving management and how to formulate it. The Extended Linear Expenditure System (ELES) model is suggested to evaluate the payment ability of students for water use. To rise price up cannot achieve the purpose of water-saving and quality of life will be reduced. Gradational water price can be used to solve the problem; the water price is different according to the calculation of water consumption.To save irrigation water, this thesis proposes the method of water-saving irrigation and to reuse the reclaimed water and rainwater. Sprinkler irrigation system with local micro spray irrigation system and intelligence supervisory system of greenhouse on GPRS should be adopted. In campus, roofing and road rainwater collection and storage technologies and low-lying green can be used. A suitable management system is proposed.
