Water Pressure Problem Solved in Tehran

After torrential rains in Tehran last week, potable water in Karaj and Latyan Dams became terribly muddy and water treatment plants stopped working for 14 hours, managing director of Tehran Province Water and Wastewater Company said.
“Reduction in water pressure and quality in homes in Tehran (especially in the east and southeast) on Friday and Saturday was due to above-normal mud levels in dams that created problems in the network,” Mohammadreza Bakhtiari was quoted as saying by ILNA.
In muddy conditions (when mud concentrations are above 10,000 units in rivers and dams) treatment facilities stop working because the maximum mud concentration they can process is 4,000 units. 
He noted that the problem was solved and water in the network is now at normal pressure and quality.
