The head of State Inspectorate Organization of Iran has asked Tehran Water and Wastewater Company as well as agent banks to accelerate the construction of phases 7 and 8 of the South Wastewater Treatment Plan.
During a visit to the plant in Tehran on Friday, Zabihollah Khodaeian added that although a long time has passed since the launch of the executive operations of the development plan, the project has registered only 10% progress and the related bodies need to speed up the process, ILNA reported.
“According to the report provided by experts, with the completion of the project, millions of cubic meters of wastewater will be collected and treated per year, which will play an important role in the development of agricultural lands in the vicinity of the plant,” he said.
is the biggest of its kind in the country. Six units of the plant are operational, but two more units are needed due to the population density of southern areas.
The units currently cover 3.15 million people and treat 246 million cubic meters of wastewater per annum. With the two new units, the plant will provide services to 4.2 million people.
The output of treatment plant is used mainly for agriculture and irrigation. The resulting sludge (as compost) is used as fertilizer.
As long as South Wastewater Treatment Plant in the capital is not developed, at least 30% of tapwater in these regions should be supplied from underground resources that have lower quality compared to dam water.
Over 220 wastewater treatment plants are operating across Iran and total sewage treatment capacity has reached 11 million cubic meters per day. About 30 other plants are under different stages of construction.
Over 7.5 billion cubic meters of usable water are produced annually, of which 4.3 bcm are wasted. Less than 25% of wastewater are recycled, which demands those in charge of water affairs to pay greater attention.
