Haya Water Company and a consortium of Cadagua / Galfar Engineering Company have signed an agreement for building a new sewage treatment plant (STP) at Darsait in Muscat.

Sultan bin Hamdoun Al Harthy, board chairman of Haya Water Company, said that this project, with a total cost of more than RO 37 million ($96 million), is one of the most important stages of Muscat wastewater project master plan, which started in 2005.

He added that the new Darsait STP is expected to be completed within 1095 days.

Darsait catchment is completely situated within the Greater Muttrah province and covers the areas of Wadi Al Kabir, Hamriya, Ruwi, Bait Al Falaj, Darsait, Coastal Darsait, Aynt, Muttrah, Muscat, Sidab and Al Bustan.

All the areas in the Darsait catchment will be provided with sanitary sewer network(s) that will discharge their collected wastewater into Darsait sewage treatment plant.

Currently, there is an existing sewer network at Darsait catchment that covers the areas of Ruwi, Bait Al Falaj, most parts of Darsait, small portions of Muttrah and small parts of Wadi Al Kabir.

The remaining portions of Darsait (Coastal Darsait & Aynt), remainder of Wadi Al Kabir and Hamriya areas will be provided with a new sewer network which is under construction and expected to be completed by the end of 2012.

The main treatment process at Darsait STP shall be based on membrane biological reactor (MBR) technology in water treatment, and is equipped to handle a maximum daily flow of 50,000 cu m per day.

It is considered one of the best systems in the world, because it guarantees the production of high quality pollutants-free treated water, a statement said.

As part the works, new treated effluent storage reservoirs and a transfer distribution pumping station shall be designed and constructed by the contractor.

The contractor will provide a telemetry link to connect the new Darsait STP facilities to the Haya’s central control room at the existing Al Ansab STP together with the provision and installation of all necessary instrumentation and control systems. – TradeArabia News Service
