Maintenance of Quriyyat desalination plant on Feb 28, 29

The Main Emergency Committee at Diam held a meeting to discuss the programme for performing periodic maintenance of the plant on February 28th and 29th.

The Main Emergency Committee at Diam held on Wednesday a meeting at its main office in Bausher, to discuss the request submitted by Hyflux Oman, the owner of the Quriyyat desalination plant, on the programme for performing periodic maintenance of the plant on February 28th and 29th.

The meeting reviewed the most important precautionary measures that will be taken to reduce the impact of the water supply during the maintenance period, which will continue for 48 hours as the station feeds the wilayats of Quriyyat, Al Amerat, Muttrah, Muscat, and parts of Bausher.

The sub-emergency committees of Diam in the affected wilayats have been activated to ensure the alternative water sources that will be provided, such as making sure to raise the water levels in all major and subsidiary collection tanks, and activating Reciprocating pumping between Quriyyat, Al Ghubrah and Barka desalination plants, in addition to using wells in the wilayats.

The authority urges all subscribers to take the necessary measures and continue to rationalise water consumption


The Public Authority for Water (DIAM) completes consultancy studies for the aquifer storage and recovery (ASR) project from underground reservoirs in the Sultanate of Oman

DIAM has launched an international tender to complete the detailed consultancy studies of the water storage and recovery project from aquifers, for the sites that were identified in the first phase of the project as the most promising for this type of project.
During the past year, DIAM conducted, in cooperation with the relevant government entities, an economic and technical feasibility study to implement the water storage and recovery project from aquifers (ASR) in the Sultanate. The study concluded with positive indicators for the implementation of the project, where about 14 sites were found suitable for the implementation of the project in a number of the wilayats of the Sultanate, of which four sites were labelled as are more suitable and encouraging sites: Al Khoudh in the Wilayat of Seeb, Adam Wilayat, the As Sharqiyah Sands and Wadi Abu Karba in Dhank Wilayat. This project is considered one of the strategic projects that help optimizing the exploitation of the water produced from desalination plants and contributes to achieving water security, especially in emergency situations.

An international tender has been launched to attract international companies specialized in such projects, and the scope of work in the tender includes carrying out detailed studies of the four most encouraging sites with the accompanying project of exploratory drilling, geological and hydrogeological analyses and the implementation of a pilot project for one of the sites.
The ASR system is expected to provide cost effective solutions to meet the growing demand for water in the Sultanate, as the water will be stored in periods of low consumption and then used in cases of peak water demand or in emergency situations. The economic feasibility of this system stems from storing water in aquifers, being underground solutions instead of building huge concrete water tanks above ground.
It is worth noting that the main reason for applying the water storage and recovery system from underground reservoirs in many countries of the world is the low economic cost of the system for providing water during peak demand periods. This system could provide large quantities when demand is highest at low cost, which is not available from alternative options that require the construction of additional desalination plants or expensive concrete water tanks on the surface of the earth. The system will also contribute effectively in emergency situations in the event of seawater pollution or the occurrence of the “red tide” phenomenon in the seas of Oman. An initial indicator shows the possibility of establishing projects that have enough storage capacity for three months of demand, each with a recovery capacity of more than 90,000 cubic meters per day.
It is expected that the demand for water will increase by an average of about 5% annually during the next seven years, which requires searching for the best options needed to strengthen the potable water supply system.

Diam rolls out tender for underground reservoirs

The Pubic Authority for Water (Diam) has rolled out an international tender for the completion of elaborate consultancy studies for storage and retrieve of water from reservoirs that will be set at select locations designated in the first stage of the project.

The strategic project will optimize the storage and utilization of water produced at water desalination plants as well as contribute significantly to achieving water security targets specially at times of emergency. It is expected to provide viable low-cost solutions to meet increasing demand for potable water in the Sultanate.

The water will be stored in the period of low consumption to be used at times of high demand. The project is considered economically feasible since the water will be stored underground instead of building huge overhead reservoirs known for their high financial cost.

Last year, Diam completed the economic feasibility and technical study for the execution of a project for underground water reservoirs. The study designated 14 locations that were considered the most suitable for setting up the underground reservoirs including four locations in Al Khoudh, Adam, Al Sharqiyah sands, Wadi Abu Karba in Dhank. A tender was rolled out inviting specialized international bidders to contend for the project. The successful bidder will conduct elaborate studies in the four sites in addition to the digging of exploratory wells, conducting geological and hydrological analysis and executing demo projects in the designated sites.


Strategic reinforcements on the main water transmission line in Dakhiliyah Governorate

Diam is taking actions to minimize the effects of water shortages during the 48-hour improvement period.

Diam begins the work of linking a number of new water projects in Muscat and Dakhliyah governorates with the main water transport system during the period of 2-3 December 2019, which will last for 48 hours.

Eng. Abdullah bin Mohammed Al Nuaimi, Director General of Operations, said that the process of linking the new pumps to the main line improvement project in Al Dakhliyah governorate with the main pumping station in Barka comes to complete the enhancement of the water network system in the province in addition to raising the efficiency of water pumping stations in the wilayat of Seeb and enhancing the interconnection between desalination plants.

Eng. Abdullah Al Nuaimi added that measures have been taken to reduce the effects of water shortage on Al-Dakhliyah governorate. He also confirmed that Diam has activated the work of the main emergency committee and emergency committees in the states by raising water levels in all the main collection tanks in addition to activating the fields of wells belonging to Diam in the provinces which are used in emergencies.

Al-Nuaimi also explained that Diam has reached out to a number of government and private entities who benefit from government water in development projects to urge them to rationalize the use during this period, which contributes to the provision of quantities of water in addition to direct communication with the governors and walis, and members of the Shura Council & municipal councils in all states.

The Director General of Operations said that Diam invites all beneficiaries of the water supply service in the areas to rationalize water consumption during the period mentioned. Al-Nuaimi added that, in case of any queries or observations all citizens and residents can communicate with the Diam call center (1442), which operates 24 hours a day all week.
