Abstract

Iran is geographically located in the arid and semi-arid region of the earth, with an average rainfall about 250 mm per year, which is one-third of the world's average rainfall. So that, 84% of the country's catagorized as arid and semi-arid area and only 16% of it is in the semi-humid and humid regions. However, total per capita consumption of drinking water in Iran (including commercial - industrial - household - green space ...) is estimated to 220 liters per day. In addition, population growth in Iran has been increasing in recent years. Lack of proper management of available water resources has led to serious challenges in the field of water supply, especially drinking water in many cities and villages of the country. In this paper, using the 3'Rs strategy (reduction, reuse and recycling), We investigate the ways to reduce water demands at the University of Bojnrod and then discuss the possibility of using gray water, as an important part of the wastewater of the  campus. One of the important point in water management of the campuses is to pay attention to the wastewater produced in the university. The most important wastewater produced at the University of Bojnord is the restaurant wastewater, which we concentrate on the possibility of using this wastewater and its usable products.
