Azerbaijan, Baku, Sept. 29 /Trend M. Moezzi, S. Isayev/
Each year, 1.2 billion cubic meters of water is produced and distributed in Tehran, deputy director at Tehran Water and Wastewater Fariborz Salehi said, IRNA reported.
"The water supplied to the residents of Tehran comes from the Karaj, Taleghan, Lar and Latian dams and around 450 wells," Salehi said.
Underground sources supply 26 to 27 percent of the water consumed by Tehran residents and the rest comes from surface waters. In recent years, gravity is used to transfer water from Lar dam to Tehran to save electricity.
Turning of water pumps saved 4.5 billion rials (equal to $367,000 USD) in the first three months of this year (Iran's solar year starts on March 20), Salehi said.
Telemetering is used to monitor water facilities and details like the water temperature, turbidity and nitrite levels are controlled online, Salehi said.
In the agricultural sector, Tehran is facing water shortages, to the amount of 500-600 million cm. The province of Tehran requires some 2.3 billion cm of water for farming, having available only 1.8 billion cm.
Aside from the water shortages, Tehran is forced to fight unstable weather conditions and extreme air pollution. Due to weather conditions, Tehran has not seen any heavy rain in a month, which itself can lead to drought.
Compared to previous years, water in Tehran's reservoirs has decreased by 3 percent in 2011-2012.
Currently, Iran is considering over a number of proposals on solving the water problem. One of such proposals is to transfer water from the Caspian Sea to Tehran.
