MUSCAT -- Haya Water has announced more details of the scope and scale of its world-class water reuse system which is considered as the first and the largest submerged Membrane Bio-reactor treatment plant worldwide. The plant was opened officially and put into full operation on February 27.

The company has been committed since the outset to ensure that it has incorporated the most advanced and sophisticated sewage treatment technology into its project that will transform Muscat and help make it a better city for now and in the future.

The Al Ansab treatment plant includes the world's largest submerged membrane bio-reactor system with a capacity to handle up to 54,000 cubic metres of effluent every day that will double to 110,000 cubic metres a day when Phase 2 of the project is completed.

The plant, which is now up and running, receives sewage from the tanker discharge area and the newly constructed central pumping station in the Al Azaiba area as the project continues to connect private homes and businesses across the Muscat Municipality area. This will be delivered using a network of 280 km of pipeline that will transport treated effluent efficiently to Al Ansab for the final treatment process.

The Al Ansab Sewage Treatment Plant (STP) is one of the most complex and advanced ever undertaken in the region and will ensure that the city benefits from a modern, clean and healthy water reuse system that will also benefit the local community by providing treated effluent to be used for irrigation and other purposes across Muscat area.

Installing Membrane Bio Reactor technology (MBR) is a vital part of ensuring that the water available to be re-used is of the highest quality and meets stringent standards set down by authorities across the Sultanate for the use of this water.

The sophisticated nature of MBR also means that it is able to take up far less space than other treatment systems -- and this was particularly important on the Al Ansab site that is surrounded by hills making space tighter for the plant.

Haya Water CEO, Omar al Wahaibi explained: "From the outset of the project, Haya Water was determined to ensure that we installed the very best systems and technology to help ensure we can offer everyone living and working in Muscat sustainable and modern water re-use system that will bring long-term benefits to society and environment.

"Ensuring that MBR was an integral part of our water treatment plant was an essential part of that strategy -- as it is a highly cost-effective and technically outstanding solution that has met our objective of maximising the amount of treated effluent that can be used to help make Muscat a greener and cleaner city.

"It also means that through our operations Haya Water is able to make a difference to the lives of tens of thousands of Omani citizens and residents every day and help to improve their quality of life and the environment around them."

When completed, over 80 per cent of Muscat residents will be connected directly to the new modern system. It will mean an end for most residents of the need for a smelly septic tank and the requirement for a truck to come and take away waste water from private homes and businesses across the whole of Muscat -- making life healthier for families and children.

Water available for reuse from the project is being used extensively to ensure that parks and public areas of Muscat stay green and golf courses are watered. Increasing numbers of real estate developers and industrial concerns are also benefiting from the Haya Water project and its treated water.
