France’s Suez Environnement has been awarded a $37m contract to design and build the expansion of a major municipal waste facility in the Omani capital of Muscat.

Sita al-Basheer, Suez Environnement’s local subsidiary, will expand the capacity of the landfill facility to 400,000 tonnes, from the current 250,000 tonnes. The company completed construction of the existing facility in 2010.

This is the second contract the Suez Environnement subsidiary has won in the sultanate recently. The group was recently awarded a two-year contract to operate a landfill site at Nizwa, which processes all of the non-hazardous municipal waste in the Dhakhliyah region.

In October, another of Suez Environnement’s subsdiaries, Degremont, was awarded a RO12m ($31m) contract to design and operate a 18,000 cubic-metre-a-day (cm/d) wastewater treatment plant at Al-Amerat. Degremont will also provide operation and maintenance (O&M) services for a period of two years.

The Al-Amerat sewage treatment plant will use membrane biological reactor technology. The treated effluent storage reservoir will have a capacity of 16,000 cubic metres, which equates to about a day’s capacity at the design flow rate. A pumping station and pipelines for transmitting treated effluent to distribution networks will also be constructed by the contractor.
