Increase in Tehran Water Supply

Increase in Tehran Water Supply

The first phase of Mamloo dam has gone into operation, providing southern Tehran with 1.5 cubic meters of water per second (cm/s), said the managing director of the Tehran Province Water and Wastewater Company (TPWWC), ILNA reported Wednesday.
TPWWC aims to increase the supply to 2.5 cm/s in order to secure water stability in the southern parts of Tehran, Mohammad Parvaresh noted.
In addition, phases 5 and 6 of the South Tehran Wastewater Treatment Plant will be inaugurated next week at the presence of President Hassan Rouhani.
Further 1.1 million residents of Tehran will be covered by wastewater network with the two phases going into operation next week. Having had an increase of 2.8 cm/s, the plant's output will reach eight cm/s.
The five major dams supplying water for Tehran currently hold 200 million cubic meters of water, "which equals consumption of Tehran residents at the time of peak demand," the official added, noting that average precipitation rate decreased by 17 to 50 percent this year.
The mean annual precipitation is only 250 millimeters in Tehran, most of which falls during winter and spring. The most important freshwater sources in Tehran are the Karaj, Lar, Latian, Mamloo and Taleghan reservoirs.
Water management in Tehran is faced with increasing demand and waste production due to population growth and socioeconomic development, decreased availability of water per capita, large losses of urban water, and local depletion and pollution of surface and ground water.
Mamloo has a crest length of 807m and height of 89m on the Jajrood River. It became operational for agricultural purposes in 2008, and it was officially inaugurated in February 2011.
