Welcome to this week’s edition of the “Our Future Water” newsletter. In this issue, we focus on the critical relationship between water and climate resilience, exploring how innovative strategies like underground water storage, water recycling and desalination, and stormwater harvesting can enhance freshwater availability and bolster resilience to climate change.
Insights
Enhancing Underground Storage of Water to Augment Freshwater Availability
One effective approach to enhancing climate resilience is the augmentation of underground water storage. This involves the deliberate recharge of aquifers through managed aquifer recharge (MAR) techniques, where surplus water is directed into the ground for storage and future use. By capturing excess surface water and storing it underground during high rainfall, utilities can create a reliable reserve during droughts or periods of low rainfall. This method increases freshwater availability and mitigates climate variability’s impacts by ensuring a stable water supply. Furthermore, underground storage reduces the risk of evaporation and contamination, preserving water quality and quantity over the long term.

Water Recycling and Desalination for Sustainable Water Management
Water recycling and desalination are crucial for addressing water scarcity and promoting sustainability. Recycling wastewater through advanced treatments allows utilities to produce high-quality reclaimed water for irrigation, industrial uses, and even drinking, reducing pressure on freshwater sources. Desalination, converting seawater into freshwater, offers a reliable solution for coastal and arid areas. Modern technologies in desalination have become more energy-efficient and cost-effective, providing an alternative water source resilient to climate change. Utilities can ensure a sustainable and resilient water supply system by integrating water recycling and desalination.

Stormwater Harvesting: Collecting, Storing, and Treating Urban Runoff
Stormwater harvesting is an innovative strategy for collecting, storing, and treating urban stormwater as a valuable resource. Urban areas generate significant runoff during rainfall, often leading to flooding and pollution. Stormwater harvesting systems capture this runoff, treat it to remove contaminants, and store it for later use. This reclaimed water can be used for landscape irrigation, toilet flushing, and industrial processes, reducing demand for potable water supplies. Stormwater harvesting maximizes available water resources, enhances urban flood management, and mitigates the environmental impact of urban runoff.
