A water pipeline from Mamlou Treatment Plant in Pakdasht County (35 km southeast of Tehran) to Pishva County (45 km southeast of Tehran) was launched on Monday, managing director of Tehran Province Water and Wastewater Company said.
“The aim is to improve the quality of potable water in the southern regions of the overcrowded capital and control land subsidence in the Varamin Plain,” Mohammadreza Bakhtiari was quoted as saying by IRNA.
The 10 kilometer pipeline transfers 35,000 cubic meters of water to Pishva per day. It led to the decommissioning of at least 60 wells in the area where underground tables are plummeting due to excessive (80 million cubic meters per year) water extraction, he said.
Referring to the water quality, he added before Tehran's seventh water treatment plant (Mamlou Treatment Plant) was completed in January, water hardness in Varamin was 1,900 milligrams per liter.
