With the UAE set to co-host the United Nations Water Conference 2026 with Senegal in December, preparations are in full swing in the academia, where local researchers are advancing solutions to address water scarcity.
A number of national universities and research centres are taking part in the Academic Water Carnival, an initiative launched in the run-up to the landmark conference, aiming to shed light on water-related issues and challenges.
Abu Dhabi University (ADU) is among those getting ready to represent the country with a project that stretches the limits of treated wastewater, maximising its potential.
"We are looking into how we can optimise this wastewater, because it's a valuable source of water for the UAE," Prof Evan Paleologos, Director of Engineering Management and Project Management at Abu Dhabi University, told Aletihad.
ADU's research project is driven by a sense of urgency stemming from natural water scarcity. "Water is very scarce, we are utilising much more water than is available to us," Prof Paleologos said, noting that supply is largely dependent on groundwater and desalination. "It is very critical that we utilise every drop of water," he added.
Outlining the solution, Prof Paleologos said the project focuses on the reuse of treated wastewater. He added that a key component is aquifer replenishment, where soil is used as a natural filter to prevent contamination. By recharging aquifers with treated wastewater, he explained, the approach helps compensate for water extraction while maintaining groundwater quality.
Highlighting some practical applications, Prof Paleologos noted that grey water can be reused in buildings, reducing reliance on desalinated water, while small, decentralised treatment systems can support communities.
The project supports sustainability, innovation and collaboration, while improving energy efficiency by reducing reliance on desalination, he said.
ADU works closely with the Environment Agency – Abu Dhabi and Sorbonne University Abu Dhabi in developing its solutions. With its drive to innovate, the UAE is not only addressing its challenges but also setting new benchmarks for sustainable water management, Prof Paleologos said.
He noted that its forward-looking blueprints place the UAE at the forefront of global developments and could guide other nations, particularly those facing severe drought and water scarcity.
Water, he stressed, is integral to economic development, making its security a universal mission for safeguarding livelihoods and growth. "If we do not have sufficient water, we cannot sustain our population, agriculture, or industry. It is a fundamental resource for the future of every country," he said.
