Water Resources and Water Management in UAE: The United Arab Emirates (UAE) relies primarily on three key sources for its water resource and water management supply: groundwater, accounting for 70% (4,052 million m^3); desalinated water, comprising 24% (950 million m^3); and treated wastewater, constituting 6% (319 million m^3). Groundwater serves as the primary conventional water source in the country and is extensively utilized to fulfill the irrigation needs of the agricultural sector. It connects two major water bodies in the world.
In addition to conventional water sources, the United Arab Emirates depends on non-traditional water resources to address the growing water demands. Conventional sources encompass seasonal floods, springs, falls, and groundwater.
In this article, we will learn about Water Resources and Water Management in the UAE, along with how to improve water resource management in the Country.

Water Resources in UAE
Surface water resources in the UAE, comprising floodwater, dam reservoirs, small streams, ponds, and spring water, are relatively insignificant. Whether confined or flowing, these sources typically occur in areas with land slopes and are replenished by rainfall or groundwater.
- Due to the UAE’s location in a dry belt region, rainfall is limited, and floodwaters often infiltrate the ground, particularly in sedimentary areas.
- Consequently, constructing dams to capture rainwater and store surface water behind them is vital to replenishing aquifers despite significant losses due to high evaporation rates.
- On average, annual surface water flow through wadis (valleys) ranges from 23 million cubic meters (MCM) to 138 MCM.
- Groundwater serves as the primary natural water resource in the UAE. Although the total volume of groundwater is considerable at around 640 billion cubic meters (BCM), only a small fraction (about 3%, or around 20 BCM) is fresh.
- Given the arid environment of the UAE, groundwater plays a crucial role in municipal and rural water supplies, environmental preservation, and socio-economic progress. However, the majority of groundwater in use is brackish.
Water Management in UAE
Water management is critical for the United Arab Emirates (UAE) due to its arid climate and limited natural freshwater resources. Here are some key points about water management strategies in the UAE:
- Efficiency in residential landscape irrigation is promoted through a comprehensive initiative that includes educational outreach, regulatory measures, and incentive-based strategies. The goal is to decrease water usage in residential gardens.
- An initiative is underway to assess materials and technologies to mitigate the significant initial capital expenses associated with desalination plants. This evaluation focuses on reducing the capital costs involved in desalination.
- Ensuring that all 45,000 groundwater wells across the emirate have monitoring devices to track water consumption accurately. With 90% of agricultural water stemming from groundwater, particularly for Date Palms, the focus is on enhancing the efficiency of groundwater usage in date palm irrigation.
- The initiative is focused on developing comprehensive strategies to create a state-of-the-art master plan for recycled water, emphasizing robustness, dynamism, flexibility, and technological integration.
- Regarding recycled water, the initiative aims to align priorities for recycled water usage with infrastructure plans at the planning level to facilitate the smart expansion of recycled water networks.
Unconventional Water Resources in UAE
Unconventional water resources refer to those generated as a byproduct of specialized processes like desalination. They may require specific pre-use treatment or on-farm management when utilized for irrigation. Additionally, accessing such water may necessitate special technology or methods for collection.
- Cloud seeding operations primarily target the eastern mountain ranges along the border with Oman, with the objective of augmenting water levels in aquifers and reservoirs in the region.
- To fulfill the criteria set for drinking water quality, domestic water provisions primarily depend on desalinated water, constituting approximately 99% of the supply. This desalinated water is utilized in its pure form or mixed with groundwater.
- Treated wastewater stands out as a crucial alternative to address certain existing water needs and alleviate the enduring imbalance between supply and demand over the long run.
- Completing wastewater treatment facilities and expanding urban sewage networks have enabled the availability of significant quantities of treated wastewater. There exist approximately 79 medium and large-scale wastewater treatment facilities.
Water Resource and Water Management in UAE Limitations
There are still many challenges and limitations in the distribution, treatment, and other fields of water management in UAE; some of them are:
- Agricultural activities exert adverse effects on water resources, leading to the degradation of groundwater quality, given that agriculture is the primary land use in the UAE, responsible for more than 70% of groundwater utilization.
- The absence of transmission and distribution networks to serve end-users, primarily forests and private enterprises like golf resorts.
- Reduced demand resulting from the financial downturn spanning from 2008 to 2014; Cultural challenges, such as persuading farmers to adopt recycled water usage.
- In the UAE, there has been a decrease in groundwater levels and a decline in quality due to limited precipitation and extensive extraction for diverse applications.
- Desalinated water and recycled wastewater are utilized to offset the groundwater deficit.
Water Resource and Water Management in UAE Projects
Abu Dhabi’s Environment Agency is actively formulating an integrated water resources management plan (IWRMP) to establish a comprehensive array of strategies and a governance structure to enhance water management practices and achieve objectives aligned with the United Nations Sustainable Development Goal 6.
1. The Strategic Tunnel Enhancement Programme (STEP)
In Abu Dhabi, the STEP project involves constructing a massive underground tunnel system to transport treated wastewater for irrigation, conserving freshwater resources and reducing reliance on desalinated water.
2. Taweelah Reverse Osmosis Desalination Plant
Located in Abu Dhabi, this plant is one of the largest desalination facilities in the world, producing clean drinking water from seawater using advanced reverse osmosis technology.
3. Masdar City’s Sustainable Water Management
Masdar City in Abu Dhabi incorporates advanced water-saving technologies and practices to minimize water usage and promote sustainability.
4. Al Ghafat Reservoir
This project in Dubai involves the construction of a large reservoir to enhance water storage capacity and improve water security in the region.
Improving Water Resources and Water Management in UAE
Improving water management in the United Arab Emirates encompasses various strategies. While the government ensures clean and potable tap water from desalination plants, challenges arise during its distribution to households, primarily due to two sources of contamination.
- Firstly, aged and corroded pipelines introduce bacteria into the water, rendering it undrinkable. Secondly, storage tanks present another risk: deceased birds, rodents, insects, and metallic substances may contaminate the stored water.
- The responsibility for cleaning these tanks, typically required every six months, falls on property owners. However, without legal enforcement, many landlords neglect or overlook this essential task to avoid expenses.
Future Prospects to Improve Water Management in the UAE
To address these issues effectively, the government could consider the following measures:
- Replacement of outdated pipelines to prevent water contamination. Implementation of legislation mandating landlords to maintain and clean storage tanks regularly.
- Engagement of professional services for efficient and thorough tank cleaning. Conducting surprise inspections by qualified experts to ensure compliance with tank maintenance regulations.
- Implement incentives to encourage tap water usage, potentially through adjustments in bottled water pricing. Launching educational campaigns to raise awareness about the advantages of consuming tap water.
- Fostering local, regional, and global water partnerships to enhance cooperation and exchange best practices in water management.
