TEHRAN, Dec 22 (NIPNA) – Dehdasht Petrochemical Company is considering the use of treated urban wastewater as a supplementary source of water supply, as part of efforts to ensure long-term sustainability and reduce pressure on conventional water resources, officials said.

The proposal was discussed at a meeting between the chief executive of Dehdasht Petrochemical Industries Company and the head of the Kohgiluyeh and Boyer-Ahmad Province Water and Wastewater Company, according to the petrochemical firm.

Mohammad Shokri, chief executive of Dehdasht Petrochemical, said construction of a 16-kilometre water transfer pipeline from the Maroun River, designated as the project’s primary water source, had been completed, with full pipe-laying works finalised.

He said the use of non-conventional water resources, particularly treated municipal wastewater, had been emphasised under Iran’s Seventh Development Plan, prompting the company to assess urban sewage as a secondary source of supply in the coming years.

The approach aims to safeguard drinking water and surface water resources while meeting environmental and sustainable development requirements, Shokri added.

Reza Rezaei, head of the provincial water and wastewater company, said the Dehdasht urban sewage network had sufficient capacity and that his organisation was ready to cooperate on technical, feasibility and implementation studies related to wastewater treatment and reuse for industrial purposes.

The two sides agreed to establish a joint working group to conduct comprehensive technical, economic and environmental assessments of the plan, with findings to be submitted for final decision-making.
