History of Water Supply in Tehran

Until 1927, Tehran supplied its water through 26 subterranean canals with total water output of around 700 liter per second. However, in that year, the plan for transferring water of Karaj River to Tehran was launched. The canal was 53 kilometer in length and transferred water from Bilghan village in Karaj to Jamshid Abad in Tehran. It took four years to complete the canal. 20 kilometer of the canal were roofed and the rest were open; hence, there existed the risk of water pollution and loss.  This canal allowed Tehran to add 53 Sang (old scale, one meter per 3 second water run) as the city’s transfer right and 9.84 Sang as its quota. In this way, approximately 110 Sang (Around 1600 liter per second) water could be transferred to the water reservoirs (Abanbar) in houses through water canals. In 1951, the initial plan for water pipeline development was launched in Tehran for around 900,000 population and two steel pipe water lines in 24200 cubic meter per 24-hour were designed to transfer water from Bilghan Water Intake to the first water treatment plant (Jalalieh) in Tehran. The steel pipeline and Jalalieh Water Treatment Plant entered into utilization stage in 1955. In addition, to control rain and snow falls, the feasibility studies for building Amir Kabir Dam in 40 kilometer northwest Tehran (from Farhang Kouh Water Intake) close to Karaj-Chalous Road, around Km 23 near Varian Village started in 1954. The construction operations of the Dam were commenced in 1958 and the dam was completed and entered in utilization phase in 1963.



History of Company’s Establishment

Tehran Water Company was established on October 27, 1955 and after 9 years of study and different attempts to provide water, purification, treatment and distribution, the Company officially started its activities. In 1964, the Act of Establishing the Ministry of Water and Power was passed by the Parliament and in this way, the entire authorizations and duties of the Ministry of the Interior and Tehran municipality at Tehran Regional Water Organization were assigned to the Ministry of Water and Power. Based on the resolution passed by the Cabinet, Karaj Dam Organization merged with Tehran Water Organization to form a new unit named Tehran Regional Water Organization. The duty of supplying water for the Central Zone of Iran, consisting the five provinces: Tehran, Central (Markazi), Semnan, Qom and Qazvin, as  well as the development and utilization of all existing installations, development of dams, implementation of sewage and sewer system plants, developing installations on the floating rivers in water intake basin levels,  extraction from underground waters, execution of civil development plans for improving water resources, managing the installations and utilizing them in that zone were assigned to Tehran Regional Water Organization.  Subsequently in 1969, Tehran Regional Water Organization was registered as a joint stock company -a legal entity- with financial independence. In 1990 by passing the Law on Establishing Water and Sewage Companies, the duty of establishment and utilization installations for urban water distribution, collection, purification, treatment and transfer of sewage of cities were taken from Regional Water Organization and were assigned to Tehran Province Water and Sewage Company.  Since 2005, this Company has been working in the territory of Tehran Province by passing the Islamic Legislative Assembly in alignment with decentralization and formation of provincial water companies.
