Tehran Water Loss 13%

Almost 24% of Tehran's water network is over 40 years old while the useful life of water pipelines is an average 25 years, managing director of the National Water and Wastewater Engineering Company of Iran (Abfa) said.
Wear and tear of pipelines in Tehran results in 13% of waste in the transmission network, Mehr News Agency quoted Hamidreza Janbaz as saying.
“We are struggling to reduce the water loss in the network but cutting it to below 10% costs a lot,” Janbaz said. The national water network in Tehran Province stretches over 10,000 kilometers of which about 2,500 km is decrepit and needs to be replaced.
