The project is to be carried out in the city of Khansar, Isfahan Province in central Iran, IRIB news agency reported November 22.
Khansar has the record in Iran for NRW as the loss of water in this city is 60 percent, Water and Wastewater Engineering Co. Deputy CEO Hamid Reza Tashayoee said.
The project is going to be a unique one of its kind in the world and it will reduce the city’s NRW to 15-17 percent, the official said.
The NRW percentage in Iran is something about 26 percent in average, 14 percent of which is water that goes waste in pipes.
Japan is highly experienced in water management. The country’s NRW at the end of WWII was 80 percent whereas now it is four percent.
Iran is facing severe water shortage following a general drought of several years as well as extensive use of ground and underground water resources.
The high rate of real losses in Iran is shown by studies to be mainly due to old-fashioned pipeline network in distribution systems, invisible leakage, ground breakage and the water pressure on the system.
Based on an urban water management study in 2013, the number of water and wastewater companies under Iran’s National Water and Wastewater Engineering Company (NWW) was 35. The number of connections was 14447000. The system input volume was 5607000000 cubic meters. The water network’s length was 142000 kilometers. And the NRW percentage was 24.7.
