Oman Wastewater Services Company (Haya Water) is likely to select Spanish water technology specialist Abeima to build its Tanker Sewage Treatment Plant (Tanker STP) project in Misfah.
Abeima's chances to win the contract reportedly improved after it emerged as the lowest bidder for the project, estimated to cost up to $100m.
Tanker STP is due for operation by the end of 2018.
Bids were also received from the joint venture of Suez Environment and CCC, as well as VA Tech Wabag.
The successful bidder will be contracted to design, build, and operate (optional for two years) the Tanker STP facility.
Tanker STP, set is Misfah's Bausher wilayat (province), will "offer a lifeline to sewage bowser operators whose numbers continue to dwindle as homes and commercial buildings across Muscat are plugged directly into the citywide wastewater network", Oman Daily Observer reported.
The Tanker STP contract had to be refloated due to "a tepid response from contractors when it was first tendered out last year", Suleiman al Qasimi, general manager for asset management at Haya Water, told the daily.
