Oman’s Haya Water has awarded a RO26.7m ($70m) contract to Athens-based Consolidated Contractors Company (CCC) to carry out a water reuse project in the Qurum and Ilam areas of Bausher in Muscat Governorate.

The 30-month contract covers the construction of 40 kilometres of sewer pipes, 66km of lateral pipes and 10km of treated effluent irrigation channel. The project also includes the design and construction of 13 minor network pumping stations, with flow rates ranging from 3-120 litres a second, as well as rising mains that will take effluent to a gravity sewer network.

CCC submitted the lowest bid for the contract in December 2011 with a bid of RO29.09m (MEED 11:12:11). The second-lowest prices of RO31.4m and RO29.97 were submitted by Dubai-based Arabtec Engineering Services. Kuwait’s United Gulf Construction Company was the other bidder with a price of RO54.80m.

The contract will cover an area of 140 square kilometres and will serve about 120,000 people in Bausher’s Al-llam and Al-Qurum suburbs. Through the project, Haya Water intends to establish an efficient sewerage network to replace the current system of using hundreds of tankers daily to empty septic and holding tanks. The project is one of six water reuse developments. The other projects will be carried out at Seeb, Muscat, Muttrah, Amerat and Quriyat.
