Tehran Wastewater Expansion Project to Be Completed in Five Years

Tehran wastewater network will be completed by 2023, managing director of Tehran Water and Wastewater Company said at the weekend.
“So far 65% of the sewage network is complete,” Mohammad Reza Bakhtiari said, noting that construction of wastewater treatment plants is also underway, ISNA reported.
When the new infrastructure is up and running, it will help add 250 million cubic meters of (recycled) water to Tehran's water reserves per annum, and decrease the water stress in the capital city, he said.
