TM Reluctance to Use Treated Wastewater Taking Heavy Toll on Aquifers 

Tehran Municipality’s unwillingness to use treated wastewater for watering parks and green spaces is pushing the province over the edge, managing director of the provincial sewerage company said.
“TM withdraws close to 200 million cubic meters of water from underground resources for parks and green spaces annually, while wastewater treatment plants’ output in the city has exceeded 250 mcm per annum,” Abbasali Mesrzadeh was also quoted as saying by ISNA.
As per a contract between the Energy Ministry and TM signed in 2020, the latter was obliged to lay pipelines to transfer recycled wastewater from sewage treatment facilities to parks, but the initiative has not got off the ground yet, he added.
