Barka 4 – Oman’s largest desalinated water production plant

At the end of 2015, the Oman Power and Water Procurement Company floated a request for qualification for the development of an Independent Water Project with a total capacity of 281,000 cubic meters per day on the Batinah coast to meet the increasing water demand in the northern region, projected to grow by around 6 % per year. Less than 30 months later, in June 2018, the Barka IV independent water project started operation and became the largest producer of fresh water in Oman. The project underlined the singular importance of desalination Oman’s water supply plans.


The plant, located 50 km West of Muscat, claims a record low electrical energy consumption for a facility of its size thanks to the ultra-modern energy recovery process integrated in the design, thus offering more energy efficiency than the current state-of-the-art desalination systems, a crucial issue at a time when the energy mix in the region is under more scrutiny and more pressure than ever. As the largest reverse osmosis plant yet to be built in the Sultanate, Barka 4 is a tribute to the success of the technology, and a new high point for desalination in the country. The successful commissioning of the plant saves costs and single-handedly increases the national water capacity by 20%.
