Haya Water, part of Oman Wastewater Services Company (OWSC), has announced a programme to develop wastewater treatment projects worth OMR6 billion (US$15.55 billion) through public-private partnerships (PPPs).
The authority has put together a masterplan that starts this year and concludes in 2045, by which time there will be 133 water treatment plants in the country with total capacity of 979,000m3 a day.
The projects planned are located in all parts of Oman, besides the Muscat and Dhofar governorates, the largest in terms of population and surface area, respectively.
The programme is split into two stages. The first involves the development of 21 treatment plants with capacities ranging from 10,000m3 to 85,000m3 a day. These plants will serve 70% of Oman’s population. The second stage comprises 65 smaller plants that will treat 930m3 a day and supply 17% of the population.
As well as the plants, private investors will construct and operate a 2,765km-long main network and 31,350km sub-network of sewers, which will connect around 755,000 facilities, serving 4.1 million people by 2045.
The masterplan envisages private partners generating revenues from selling treated water and fertilisers.
Haya Water has not announced any details of tender processes for the treatment plants or sewer networks, or a schedule for the implementation of the planned PPPs.
