Oman’s Regional Municipalities and Water Resources Ministry has invited companies to bid for contracts for two major sewerage deals in the sultanate.
For the first project, the ministry has invited contractors to bid on the contract to build a sewage treatment plant and sewerage network system for the Wilyat of Ibri in northwest Oman. Contractors have until 7 January 2013 to submit prices for the tender.
The second contract is for the construction of a sewerage network, and design and build of a sewage treatment plant, buildings and access roads for the Wilyat of Al-Musannah.
The projects are part of the sultanate’s efforts to upgrade its sewerage and wastewater infrastructure.
In May, 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.
