The network saved the authority from more than 62 million dirhams in leaks last year
Dubai Electricity and Water Authority (DEWA) is investing in its advanced smart grid and the latest technologies of the fourth industrial revolution to strengthen its leadership and global excellence in water network losses and surpasses its global counterparts.
In 2021, DEWA’s water network losses have decreased to 5.3%. This is one of the best records in the world and compares favorably to North America, where water losses are around 15%. Such records demonstrate DEWA’s position as one of the world’s largest and most distinguished utilities.
DEWA adopts pressure management and district metering systems to identify areas with leaks. For non-visible leaks, it uses automation and digital transformation projects, acoustic technology (noise recorders, ground microphones, correlators and hydrophones) and helium gas technology used in distribution pipelines to detect them in the water network. From 2013 to 2021, 7,008 leaks were detected, saving 4,069.93 million gallons and Dh62.8 million.
Saeed Mohammed Al Tayer, MD and CEO of DEWA, emphasized that the organization applies global best practices in all its projects to increase production and operational efficiency. DEWA has made substantial savings in the development of the water network to promote its efficiency and reliability as well as to increase water flow to meet comprehensive development needs as well as growing demand. It provides its services to over one million customers in Dubai with the highest standards of availability, reliability and efficiency. DEWA’s current capacity has reached 13,417 MW of electricity and 490 MIGD of water.
“We are striving to realize the vision and directives of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the United Arab Emirates and Ruler of Dubai, to further develop Dubai’s competitive capabilities and strengthen its position We prepare for the future with scientific planning and innovation, using the latest technologies in the generation, transmission, distribution and control of water networks We also develop innovative experiences to increase efficiency and the reliability of the electricity and water networks in order to meet the growing demand for Dubai’s social and economic growth,” added Al Tayer.
The intelligent distribution management system (SDMS) supports real-time detection, location and management of infrastructure faults in the water distribution network, thereby reducing water shortage (UFW) for the distribution network stretching over 4600 kilometres.
In 2014, DEWA launched the first phase of the Supervisory Control and Data Acquisition (SCADA) center for water transmission at its sustainable building in Al Quoz. This is part of its efforts to achieve digital transformation using cutting-edge operational technology. This allows it to remotely monitor Dubai’s water network around the clock, including water transmission pipelines, pumping stations and reservoirs stretching over 2,300 kilometres. This was done by installing over 8,500 smart devices. DEWA is currently implementing the second phase of the system to include the water distribution pipelines and is steadily expanding the transmission network.
DEWA has developed its Hydronet project to use AI and Deep Learning. Hydronet saved Dh5.3 million per year by remotely monitoring and controlling Dubai’s water network. The project can be integrated with any SCADA system and provides real-time information on the current status of the network. It can also repair leaks in seconds without human intervention. This increases the efficiency of the water network and the insulation of the pipeline in Dubai, which saves time and effort. The project won the Silver Team Idea of the Year award at Ideas America 2020.
The Water Smart distribution management system increases the visibility and management of its water distribution network. It also improves automation, operational efficiency, reliability of water supplies and DEWA’s worldwide excellence in water loss reduction. It has a 24-hour centralized system for remote control and monitoring, as well as innovative intelligent equipment and systems. The system also uses remote terminal units (RTUs) installed at the interconnections between the transmission and distribution pipelines. In addition, it is connected to advanced water SCADA and hydraulic management systems. The system will improve fault location and isolation and reduce costs.
DEWA adopts Smart Ball Leak Detection to detect invisible water leaks in hard-to-find or hard-to-reach pipelines. The technology has saved 68.45 million gallons and Dh2.74 million since its implementation in April 2021.

The total investment in DEWA’s Smart Grid program amounts to more than 7 billion dirhams. A smart grid provides advanced functionality that includes interoperability across the entire electricity and water network. It is an integral part of DEWA’s strategy to develop state-of-the-art infrastructure for managing facilities and services according to intelligent and integrated systems using disruptive technologies and applications of the fourth industrial revolution. DEWA’s Smart Grid Strategy 2021 – 2035 includes six main themes: Core Capabilities; Network automation; Smart energy solutions and green mobility; Smart water; Smart Grid Artificial Intelligence; and innovative value-added services. To meet the short-term goals of its 2014-2035 Smart Grid Strategy, DEWA replaced all of its mechanical water meters with smart meters in 2020. It also began operating the Meter Analysis and Diagnostics Center smart meters, where 879,000 smart meters are read and monitored remotely. every 15 minutes.
This helps DEWA improve the availability of meter readings to 99.9%. Smart Meter Remote Monitoring has also identified and addressed 457,233 water leak reports, 16,103 faults and 7,974 load increase cases over the past three years. The number of water accounts reached 960,032 accounts at the end of 2021 compared to 666,006 accounts at the end of 2016; an increase of 44 percent. The total number of electricity and water accounts reached 2,021,508 accounts at the end of 2021.
