Muscat: The Environment Authority has conducted a comprehensive national study to analyse the quality of water produced by sewage plants and industrial wastewater treatment plants in different governorates of the Sultanate of Oman.
The study was in pursuance of the Environment Authority’s efforts to ensure the sustainable management of water resources and to explore opportunities for the reuse of treated water for environment-friendly purposes.
Dr. Imran Mohammed Al Kumzari, Director of the Department of Environmental Quality at the Environment Authority, told Oman News Agency (ONA) that the study was conducted in response to challenges facing the Sultanate of Oman amid the scarcity of its water resources. The study gains significance due to Oman’s reliance on seawater desalination and on limited groundwater stocks to meet its growing demand, he added.
Al Kumzari pointed out that treated water plants constitute one of the main pillars in Oman’s water management system. Treated water plants offer an opportunity to ease pressure on natural resources,” he explained.
The study involved the collection of accurate field data from treated water plants in the Sultanate of Oman, said Al Kumzari, noting that the data helps conduct lab analyses of the physical, chemical and biological properties of treated water, including the pH rate, suspended solids, dissolved oxygen levels, organic and inorganic pollutants and heavy metals.
Al Kumzari affirmed that a national survey conducted in 2024 and 2025 covered 217 sewage and industrial wastewater treatment plants across all governorates of the Sultanate of Oman.
The survey included field visits to all plants, from which samples of treated water were collected in accordance with precise scientific protocols that ensure the accuracy of results, Al Kumzari added.
