Tehran is becoming greener Pirhadi, a member of the Islamic Council of Tehran, in an interview with Mizan: At the beginning of the sixth period of municipal management, the total amount of wastewater received by the Municipality of Tehran from various sources was only about 6 million cubic meters. However, with the laying of the rails by the Council, the allocation of targeted credits and the approval of the master plan for raw water, this figure has increased today to more than 56 million cubic meters. With the completion of 14 water purification plants under construction and the regional distribution network, in the coming years the capital will be equipped with a sustainable irrigation system that does not depend on underground sources. With these solutions, the water load in Tehran's green belt will end completely. More details Rate on social networks.
