An investigation of the feasibility of proposed solutions for water sustainability and security in water-stressed environment

Abstract

In this paper, the possible solutions aimed at ensuring water security and sustainability in the UAE are proposed and assessed. The proposed solutions include the introduction of cost-reflective water price regimes, sustainable building codes, total wastewater reuse, leakage reduction, and diversification of supply sources in terms of renewable energy-powered desalination and cloud seeding. The feasibility of these solutions is assessed in terms of the drivers and barriers to their implementation. From the assessments, it is observed that the implementation of the actual cost of water (AED10.32/m3) would reduce water consumption by expats by 5.4%. Significant reduction in water consumption by locals could also be achieved. Domestic water savings, up to 19.8%, would be achieved by water-efficient household fixtures. Irrigation can be achieved through complete wastewater reuse and water leakage can be reduced to 10% through noise loggers, automated pumps, and pressure relief valves. A water management approach that integrates these solutions is crucial and strategic to the attainment of sustainable water balance.
