Study and recognition of the Quanat water of Rafsanjan, Sirjan and Ravar cities has been beginning since the November of 2004. Among 228 Quanat chains were studied in these cities, 165 quanat chains had a discharg more that 10 liter per second (L/Se) which were sampled. In this research oxygen, pH, discharg, water temperature and air temperature were measured in two times and in the local place. Height from the sea level, longitude and latitude were measured (by GPS Machine) in one time and in the local place and other physical and chemical factors including No2, No3, Co2, total hardness, NH3 and So4 were measured one time in the laboratory. In this manner, the condition of connection ways of considered Quanat with city was studied. With examination on the Quanat water in above said cities, all of Quant was within desired extents for aquaculture activities. Moreover in some of them, water temperature was higher than 20 degree centigrade that with some changes and in specific months can be used in aquaculture.
