Singapore is addressing its water supply challenges through the NEWater initiative, which recycles wastewater to meet rising demand. With a population density of over 8,000 people per square kilometer and limited natural water sources, the country aims for NEWater to provide 55% of its water needs by 2060, amidst uncertainties about future agreements with Malaysia.

Singapore, one of the world's most densely populated countries, faces significant water supply challenges due to its geographical constraints. With 30% of the island less than 5 meters above sea level and no natural aquifers, the nation currently relies on Malaysia for up to 50% of its water supply. As the population and economy grow, water demand is projected to nearly double by 2065. To tackle this issue, Singapore launched the NEWater initiative in 2003, which recycles and purifies wastewater to meet future needs. By 2060, NEWater is expected to supply 55% of the country's water demand. Additionally, rainwater harvesting and desalination projects are being developed, including innovative filtration techniques inspired by mangrove roots. Despite these efforts, uncertainties loom regarding the renewal of water supply agreements with Malaysia, set to expire in 2061. Notably, Singapore's water stress has decreased by 2% from 2015 to 2020, indicating progress in water management.
