Haya Water, a major government-owned water reuse company in Oman, said expansion work on the Al Ansab sewage treatment plant (STP) was progressing well and was due for completion by July next year.

The STP presently provides more than 57,000 cu m per day of reuseable water to a large network of reuse water mains, which helps provide the city with its lush and attractive appearance, said Oman Observer.

The Al Ansab Phase Two STP project, which was put up for tender in an international open bid, is the first sewage treatment project that Doosan Heavy Industries & Construction had won in the Middle East, it stated.

With the expansion, Haya aims to double the pumping capacity at the An Ansab STP from 130,000 cu m/day to 260,000 cu m per day, it added.

One of the most complex and advanced projects ever undertaken in the region, Al Ansab STP expansion is being done to ensure that the city and the local community benefit from a modern, clean and healthy water reuse system by providing treated effluent for irrigation and other purposes across Muscat governorate.

The plant will be the largest membrane bioreactor facility in the Middle East, capable of treating up to 150,000 tonnes of sewage per day, it added.
