Tehran Sewer System Expanding

Tehran wastewater network development is making reasonable progress (77%) and is planned to be launched by 2021, the technical and engineering deputy manager of the National Water and Wastewater Engineering Company (Abfa) said Monday.
"Close to 7,000 kilometers of pipelines have been laid in and around Tehran to connect the network to wastewater plants under construction in the south and west of the city," the Persian-language economic newspaper Donya-e-Eqtesad quoted Alireza Sadatifard as saying.
Expansion of wastewater network has been a priority, but lack of funds plus rapid expansion of urban areas has slowed the process.
