DEWA uses drones to ensure quality of desalinated water according to highest international standards

Dubai, UAE, 28 April 2022: Dubai Electricity and Water Authority (DEWA) continues to develop a world-class infrastructure supported by assets exceeding AED 200 billion owned by DEWA and its subsidiaries as well as further investment of AED 40 billion over five years in the energy and water sectors. This helps DEWA enhance its production capacity to meet the growing demand for electricity and water. DEWA uses the latest Fourth Industrial Revolution technologies, including drones, to provide its services according to the highest quality, availability, reliability and efficiency standards.

Sirb drone initiative

DEWA harnesses the drone technology within the Sirb initiative, which includes using advanced drones to support Dubai’s growing infrastructure. DEWA has developed its use of drone technology by utilising state-of-the-art upgradable technologies such as high-definition cameras that are equipped with night-vision and laser technologies, GPS sensors that can measure pressure, height, magnetic fields, and use ultrasound scanning. DEWA has several types of drones such as multi-rotor hydro, fixed-wing, multi-rotor and underwater Remote Operated Vehicles (ROV)s.

In water desalination, ROVs are used for underwater inspection of water intake infrastructure. Drones are also used for boiler inspection during annual overhauls, and also in videography and site inspections. In 2021, the Generation Division completed over 90 flights using robots to support the delivery of water and electricity services at the highest levels of quality, availability and reliability.

Water quality checks

DEWA provides desalinated water according to the highest international standards of safety and quality as well as the World Health Organisation (WHO) standards of production, transmission and distribution of drinking water. DEWA ensures drinking water quality through round the clock monitoring. Samples of seawater entering the power and desalination plants are collected to ensure a sufficient level of free residual chlorine to maintain the disinfection process for protecting the equipment. DEWA has installed instruments for continuous monitoring of seawater parameters such as pH, temperature, salinity, and dissolved oxygen. DEWA also has regular schedules to collect water samples at different stages of the desalination process to ensure drinking water quality. DEWA analyses the seawater inlet and brine discharge samples from the power generation and desalination process to study its physical, chemical and microbiological parameters to ensure compliance with the UAE regulations.

490 MIGD of desalinated water

DEWA currently has 43 Multi-Stage Flash (MSF) water desalination units with a total production capacity of 427 million imperial gallons of desalinated water per day (MIGD) at the D-, E-, G-, K-, L, and M Stations. It also has 2 SWRO plants with a production capacity of 63 MIGD. DEWA’s total production capacity of desalinated water is 490 MIGD at the Jebel Ali Power Plant and Desalination Complex. DEWA aims to increase its SWRO production capacity to 303 MIGD by 2030, reaching 42% from its current share of 13%. The desalinated water production capacity will reach 730 MIGD by 2030. The increased production capacity of decoupling water desalination from electricity generation will save nearly AED 13 billion by 2030 and reduce 44 million tonnes of carbon emissions.
