The new plant, built at a cost of $226 million (RO87 million), will provide sustainable alternatives to the disposal of water associated with oil extraction and will reduce gas emissions by 48,000 metric tonnes annually.
The opening ceremony will be held in the presence of the governor of Dhofar on February 1, according to the Oman Observer.
The report said the new facility can be used for vegetation to create a desert oasis for wildlife.
Rima's water treatment plant will be capable of treating about 60,000 cubic metres per day of water associated with oil production operations, according to the report.
It added, "This is higher than the project’s design capacity of 40,000 cubic metres per day, thereby reducing energy consumption by 10 gigawatts."
