The Royal Commission for Jubail has invited contractors to submit bids for the contract to build a sewage treatment plant at Ras al-Khair Minerals Industrial City.

The sewage treatment plant will have an initial capacity of 8,333 cubic metres per day, which will be expandable to 12,500 metres per day. The plant will contain two treated sewage storage (TSE) tanks with a capacity of 9,000 cubic metres each and a TSE pump station.

The Royal Commission has set an initial submission date of 31 October for the tender.

Speaking at MEED’s Saudi Arabian Energy EPC Conference in April, Ahmed al-Balawi, general manager for technical affairs at the Royal Commission for Jubail & Yanbu, said the commission would be tendering 29 contracts worth SR6bn ($1.6bn) for infrastructure work at the minerals city.

The commission has been allocated an area covering 94 square kilometres in Ras al-Khair, which is being developed mainly to accommodate industries being set up by the Saudi Arabian Mining Company (Maaden).

Maaden has two large joint-venture projects at Ras al-Khair. One is a 3.4 million tonne-a-year phosphate complex it owns with Saudi Basic Industries Corporation (Sabic), while the other is a $10.8bn joint venture aluminium project with the US’ Alcoa that is currently under construction.
