At the present time, because of high water demand in Yazd province, increasing consumption of water, lack of suitable replacement for wells and aqueducts, lack of permanent rivers, and also low rainfall, have caused negative water balance in this region. For this reason reuse of effluent wastewater of Yazd Waste Water Treatment Plant (TWWTP) has been evaluated and studied as a main replacement for below consumers: 1-Agriculturing2-Industrial reuse. 3-Indesertification 4-Artificial groundwater recharge 5-Green area of cities and between cities. 6-Urban utilities i.e: carwash, fire station, resorts … Yazd wastewater treatment plant operates with natural stabilization pond method which is consisted of one anaerobic pond and two facultative ponds and the effluent wastewater rate will reach up to 3480 liter per second within year 1415. In this study according to proximity of consumption centers in YWWTP, identification and priorities in different sections such as agriculture, industry and etc. Yazd-Ardakan plain and Bahadoran plain were selected as the project boundary. Then, the mentioned consumers were evaluated from the technical and economical aspects therefore quality, quantity, transmission and costs were studied.
