The Treasury Department plans to award a contract to Vongsayam Korsang Co, the winning bidder of its concession to manage and operate the main water transmission pipeline system in eastern Thailand.
The department's director-general Prapas Kong-Ied said the move follows the Supreme Administrative Court's decision on Thursday to refuse an interim injunction against the project.
Mr Prapas said the department would sign the contract with Vongsayam soon, as the issue has been postponed since August.
