Oman’s proposed new sewage treatment plant (STP) project, estimated to cost about $100 million, has attracted tenders from three global firms, a report said, adding that the bids are currently under evaluation.

The plant in Misfah in Bausher Wilayat will cater to sewage transported by bowser trucks long after much of Muscat has been connected to a world-class sewerage collection system, added the Oman Observer report.

Bids have been received from Spanish-based global integrated water technology specialist Abeima – which has submitted the lowest bid – Suez Environment and CCC and from India-based multinational VA Tech Wabag, the report said.

The successful bidder will secure a contract to design, build and operate the tanker STP at Misfah, which is expected to start operations by the end of 2018.
