Water Resources in UAE

Water resources in the UAE can be classified into two main categories: conventional, such as surface water (including aflaj water systems, springs and dams) and groundwater (shallow and deep aquifers), and non-conventional, such as desalinated water, treated wastewater and cloud seeding.

Water Infrastructure in Sudan

Dams are the major Water infrastructure in Sudan .There are six dams across the Nile in the Sudan. These are:

• Sennar on the Blue Nile. Built in 1925 (capacity 0.07BCM);
• Jebel Awlia on the White Nile. Built in 1937 (capacity 3.0BCM);
• Khashm al-Girba on the Atbara. Built in 1964 (capacity 0.8BCM);
• Roseires Dam on the Blue Nile. Built in 1966 (heightened in 2014, capacity 7.0BCM);
• Merowe Dam on the Nile. Built in 2009 (capacity 12.0BCM);
• The Atbara/Setit Dam C

Challenges of Wastewater Treatment and Reuse in the MENA Region

The rate of wastewater treatment is still low in many MENA countries, and reuse faces many challenges like; preference for freshwater over wastewater, inadequate information on the status of reuse and disposal of wastewater, and incomplete economic analysis of the wastewater treatment and reuse options

Why is Wastewater Reuse Important for MENA Countries?

There are many benefits of wastewater reuse. The environmental benefits include reducing the pollution of water resources and sensitive receiving bodies, and controlling saline water intrusion through groundwater recharge. Wastewater reuse also presents economic value by providing significant additional amounts of water and contributing to the conservation of freshwater resources. Additionally, it provides nutrient-rich water for irrigation and reduces the need for chemical fertilizers.

Water Resources and Quality in Iran

The total long-term annual renewable water resources are estimated at 120BCM, of which about 78BCM go to surface run-off, and groundwater recharge is estimated at about 42BCM per annum, 11BCM by qanats (underground water supply systems) and springs, plus 31BCM by wells.

Water Uses in Iran

In the year to date, the total agricultural, municipal and industrial water withdrawal has been about 100BCM, of which 41BCM from surface water, 58.8BCM from groundwater (qanats and wells) and 0.2BCM from desalinated water

Water Infrastructure in Iran

Dams have always played an important role in harnessing precious Iranian water reserves, and the long-term objective of Iran’s water resources development plan is based on the control and regulation of water through dams. In 2015, a total of 647 dams were in operation, of which 352 are considered significant reservoirs, with a total capacity of 48.39BCM.

Water Management in Iran

According to Iran’s water legislation, three ministries are directly responsible for water resources assessment and development, and namely are : The Ministry of Energy (MoE) , The Ministry of Agriculture (MoA), and The Department of the Environment (DoE).
