The Al Ansab sewage treatment plant in Muscat ... a key expansion project by Haya Water which will boost capacity by 67,700 cu m per day.

Oman Wastewater Services Company (Haya Water) has unveiled an RO6-billion ($15.58 billion) masterplan for 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 work on the plan in mid-2014 after the government delegated Haya Water the task of building, developing, managing and maintaining sanitary drainage utilities at the governorates, which were previously managed by the Ministry of Regional Municipalities and Water Resources.

 Haya Water serves 44 wilayats with varying population densities 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.

 Al Qasmi pointed out that the first stage includes 21 water treatment plants with capacities ranging 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 plants 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 tonnes 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.
