Oman Wastewater Services Company has unveiled an RO6 billion ($15.58 billion) masterplan for the future sanitary drainage projects, which cover all parts of the sultanate except the Muscat and Dhofar Governorates, an Oman News Agency report said.
The 2018- 2045 masterplan seeks to integrate the public-private partnership in building the plants and benefit from the revenues generated through the sale of treated water and fertilisers, Suleiman bin Khamis Al-Qasmi, director general of asset management, said at a seminar attended by representatives of the various stakeholders.
He said the company started with the plan after the government delegated Haya Water in mid-2014 with the task of building, developing, managing and maintaining the sanitary drainage utilities at the governorates, which where managed previously by the Ministry of Regional Municipalities and Water Resources.
Haya Water serves 44 wilayats with varying density of population and topography.
He added that as per the masterplan, the number of water treatment plants will reach 133 with a total capacity of 979,000 cu m per day. The plants will serve about 4.1 million people by 2045.
He pointed out that the first stage includes 21 water treatment plants with varying capacities between 10,000 and 85,000 cu m per day. The plants will cover 70 per cent of the sultanate's population in the nine governorates. The second stage includes 65 medium water treatment plant that will cover 17 per cent of the population and will produce about 930 cu m per day. The plants are expected to produce 370 tons of sludge.
"The 2,765-km-long main network and the 31,350-km-long sub-network will cover 86 areas or 4.1 million people by 2045 or 86 per cent of the coverage level. About 755,000 facilities will be connected to the water treatment network," he added.
