Smart Meters and Water Demand Management: Perth’s Path to Efficiency
Urban areas worldwide face intensifying water scarcity driven by climate change and population growth. Cities are responding with innovative solutions that promote efficiency and conservation. Water demand management (WDM) plays a central role—combining smart technology with behavioral change to ensure sustainable water use across households, industries, and utilities.
At the forefront of this transition, Perth, Australia, is deploying smart water meters that provide real-time data to detect leaks, monitor consumption, and optimize network performance. Through its Smart Water Meter Pilot (2023–2025), Perth is leading the way with the installation of 16,000 meters across residential and commercial properties, allowing precise water tracking and early leak detection. These insights will guide Western Australia’s broader rollout, reducing waste and enhancing long-term water resilience.

Singapore’s Smart Water Management: A Global Model of Innovation and Integration
Facing limited natural resources and rising demand, Singapore has developed a globally recognized model for integrated, technology-driven water management. Its Four National Taps strategy, combining local catchment, imported, desalinated, and recycled water (NEWater), ensures a diversified and secure water supply.
Singapore’s Public Utilities Board leverages smart technologies, including real-time monitoring, predictive analytics, and digital water meters, to manage usage efficiently, detect leaks, and optimize operations. Complemented by international partnerships and strong public education, this system demonstrates how digital innovation and governance can enhance resilience in water-scarce regions.
