Muttrah Sewage Project inaugurated

23 Dec 2020

Continuing the development and expansion of sewage projects in Oman, Haya Water inaugurated the Muttrah Sewage Project, constructed at a cost of RO60mn, on Wednesday. 

The project includes a new sewage treatment plant (STP) in Darsait and networks for sewage and treated water in Hamriya, Ruwi, Bayt al Falaj, Darsait, Aint, Darsait al Sahel and Muttrah, in addition to the city of Muscat.

The capacity of the new Darsait station is 37,500m3 per day, and is designed in a way to be expanded in the future to reach 50,000m3 per day in line with the urban expansion in the area. 

The project was opened officially under Eng Isam bin Saud al Zadjali, chairman of Muscat Municipality, in the presence of Shura, municipal council members, citizens, as well as Haya Water’s strategic partners and officials.

Suleiman bin Khamis al Qasmi, acting CEO, Haya Water, said, “The new Darsait STP was established to replace the old station on the same place, as the old station no longer absorbs the amount of wastewater flowing from the areas served by the network due to the population and urban growth.”

Qasmi added, “The new Darsait plant is designed and constructed using the latest technologies used in wastewater treatment in the world, which produce a high-quality treated water that can be reused in the irrigation of gardens and parks and many industrial, construction and other uses.”

Eng Abdul Qawi al Yafai, general manager – Operation and Maintenance at Haya Water, said, “Earlier, Haya Water conducted experimental operations of the Darsait plant, which was successful, and the plant is currently undergoing a performance test which is expected to be completed by January. Nowadays, all wastewater flows are diverted from the old station to the new one.

“The new plant produces triple-treated water using the Membrane Reactor Technology. The plant will effectively contribute to reducing the effects of environmental pollution resulting from sewage water leaks into the groundwater. In addition, it will also have a positive role in dropping the emission of polluting gases into the air.”

Eng Khalid al Lawati, general manager – Projects at Haya Water, said some 2,400 buildings in Wadi Kabir area will be connected to the new Darsait station and it is expected to be completed in mid-2021. 

“The lengths of the connected sewage networks are more than 223km, and treated water networks of 21km have been extended in the area.” 

Darsait STP will be operated and controlled in an automated manner, so that it will be linked to the central control system of the Al Ansab station, which allows employees to monitor the performance of the station and control its operations remotely.
