Consuming energy and its costs in the irrigation network of Moghan plain analysis in WaterGems Softwar was estimated for three different methods using the grouping intakes method of lands and assumed that no changing of irrigation systems and compared with the existing strategy. The height range of 210-220 meter from sea as optimize height recommended wich 77 % of area was less than that. The result showed that the application of PS2 station could be provided pressure required for irrigation form 506 ha of lands. The annually energy costs were this existing strategy with 90 Rials rate 0.87, with 1000 Rials rate 9.65 million Rials per hectare. Althogh total costs irrigation work was 350.93 and 1261.12 billion Rials. While the annually energy costs in the grouping intakes method with 90 Rials rate 0.55 and with 1000 Rials rate was equal 6.14 million Rials per hectare and its total costs were 324.21 and 895.7 billion rials. Provide PS2 station was casued to decrease at consuming energy and number of pressur relif valves respectively about 37.2% and 44% compared to the existing strategy. Applying the grouping intakes method in the design of irrigation under pressure systems will reduce the costs of energy and irrigation supplies and become more economical of agricultural products.
