Iran, with 1,648,195 square kilometer area is placed in a dry zone of the world. Average annual precipitation of Iran is equal to 250mm. It is predicted that, in 1400 (2021) the volume of water per capita per year will be about 1300 m3. Qazvin plain irrigation network is placed in 150 Km west of Tehran. Totally 278 MCM volume of water is conveyed by 9 Km tunnel from Taleghan storage dam into Ziaran diversion dam and then convey to Qazvin irrigation network. Main canal and laterals have concrete lining and have cumulatively 1100 Km length. Capacity of main canal varies from 30 to 3 m3/sec. Total irrigated area by this network is equal to 80,000 ha. Currently, "Utilization & Maintenance of Qazvin Irrigation Networks Company" under surveillance of "Ministry of Power" manages the distribution network. Governmental system is unable to manage network utilization correctly; furthermore, farmers don’t have sense of ownership about the network and their related structures. Farmers don't play effective role on water distribution affairs. Thus, network dose not have appropriate function. This paper suggests applicable techniques upon rural cultures, customs and manners. For participate "Water User Associations (WUA)" on irrigation management. In this way, legal impediments and lack of laws are considered. Participate WUA's on Qazvin irrigation management must be a gradual process and done during 5 years. For the first & second years, while participate legal representatives on utilization & maintenance of irrigation networks, 51% stocks of present company will be transfer them. In third & forth years, laws must be modified and legal impediments remedy. Farmers need to learn skills and educate about network utilization. This stage contains these required educations. Final goal will be accepted after fifth year and all affairs on irrigation management will be transferred for WUA's.
