TPWWC: Tehran Districts to Have Own Sewage Treatment Plants

Tehran Province Water and Wastewater Company plans to build wastewater treatment plants in some districts, the managing director said.
“A memorandum of understanding was signed with the Tehran Municipality at the weekend to build the first local plant in District 22, westernmost part of the city,” Mohammadreza Bakhtiari was quoted as saying by ISNA.
There are plans to build another small-scale plant in District 4, eastern most part of the capital.
"The treated wastewater of each district will be used to water green spaces in the same region," the TPWWC official said.
