Oman Wastewater Services Company (OWSC) has signed two contracts for implementing the Al Seeb waste water project, according to media  reports.

Abdullah bin Abbas bin Ahmed, chairman of the board of directors of OWSC signed the two-contracts- Al Maabela Gravity Drainage Network with Arab Contractors, and Al Seeb Costal Strip Vacuum Sewers Networks with Galfar  worth more than RO145 million ($377 million), said a report in the Oman Times.

Omar bin Khalfan Al Wahaibi, chief executive officer of OWSC, said that the $Al Seeb Costal Strip Vacuum Sewers Networks project, signed with Galfar and worth RO86,904,894 ($225,721,134), invoves construction of 270km long vacuum sewers network in the costal strip areas, north of Sultan Qaboos highway.

Ten vacuum stations will be constructed in the appointed places to suck wastewater through a network of vacuum sewers, the report said. The wastewater collected in the vacuum stations will then be transferred to the main sewage treatment plant through pumping.

The OWSC uses such technology after studying the topography and soil conditions of the area and it was discovered that the level of underground water is high and the area is flat and hence vacuum sewers system is the most feasible technology.

The project will cover Manuma, Maabela North, Gashbeh, Sharadi, Al Seeb old town, Wadi Al Luwami, Hail North and Mawaleh North. The construction work for both projects is expected after two months.
