Oman has unveiled a $15.6bn (OMR6bn) masterplan to develop sanitary drainage projects.
The 2018-2045 programme has been developed by Haya Water, part of Oman Wastewater Services Company (OWSC), and includes the scope for public-private partnerships (PPPs) during the construction and operation stages.
All parts of Oman, except the Muscat and Dhofar governorates, are included within the masterplan.
Suleiman bin Khamis al-Qasmi, director general of asset management at Haya Water, said the masterplan would raise the number of water treatment plants (WTPs) in the sultanate to 133, with total capacity increasing to 979,000m3per day.
Stage 1 of the project includes 21 WTPs with capacities ranging between 10,000m3to 85,000m3per day. These plants will cover 70% of Oman’s population, across nine governorates.
The programme’s second stage includes 65 medium WTPs that will serve 17% of the population, producing 930m3per day. Up to 336t (370 tons) of sludge is expected from the plants.
“The 2,765km-long main network and the 31,350km sub-network will cover 86 areas, or 4.1 million people, by 2045,” al-Qasmi said. “About 755,000 facilities will be connected to the water treatment network.
“The masterplan […] seeks to integrate the [PPP model] in building the plants, and benefiting from the revenues generated from the sale of treated water and fertilisers.”
Al-Qasmi said the masterplan’s development began after Haya Water was delegated by the Omani government in 2014 to build, develop, manage, and maintain sanitary drainage utilities in the country.
These activities were previously implemented by Oman’s Ministry of Regional Municipalities and Water Resources, ONA reported.
