To reduce demand for freshwater in the arid province of Qom, an industrial wastewater treatment plant was launched by West Asia Steel Company, the managing director of the firm said.
“The facility has a daily reclamation capacity of 400,000 liters of industrial effluent and cost $3 million,” Gholamreza Khaliqi was quoted as saying by IRNA on Sunday.
The project is expected to help preserve at least 150 million liters of underground water a year, he added.
