World Water Day
Today is World Water Day, a good moment to reflect on something we often take for granted. Freshwater is limited, under growing pressure and essential for people, places and the organisations that rely on it. In the built environment, how we use and manage water make a difference. Using less water is great for sustainability, but it also helps cut costs and makes buildings more resilient when scarcity hits. With drier summers becoming more frequent and infrastructure stretched, now is the perfect time to rethink how we use this vital resource.
Good water stewardship supports three big goals:
1. Stronger resilience for the future. Efficient buildings are better prepared for supply issues, restrictions and tighter regulation.
2. Lower operating costs. Using less water means paying for less water. Many upgrades pay back quickly.
3. Healthier local environments. Reducing demand protects rivers, wildlife and catchments that are already under pressure.
Whether you’re making changes at home, managing or designing buildings, or leading sustainability strategy, there are plenty of simple and impactful steps you can take:
· Understand how much you use: carry out a water‑use assessment to spot savings and risks.
· Improve efficiency across your sites: install low‑flow taps, dual‑flush toilets and efficient appliances. Fix leaks quickly to prevent big losses over time. Review cleaning and production processes and choose options that use less water.
· Use data to guide your decisions: fit smart meters or monitoring tools that give you real‑time visibility and help you spot leaks early.
· Make the most of alternative water sources: harvest rainwater for toilet flushing, irrigation or cleaning. Use greywater systems where allowed, reusing lightly used water for landscaping or gardening.
· Choose water‑friendly landscapes; plant drought‑tolerant or native species that need less irrigation. Keep irrigation systems efficient and well maintained.
· Protect local waterways: reduce or remove chemicals that might end up in water bodies. Provide spill kits and training to help staff prevent accidental pollution. Stay compliant with Environment Agency discharge permits if you release water into rivers or sewers.
· Think about your supply chain too: select suppliers with strong water stewardship practices, especially where products have high water footprints.
Water scarcity is becoming a growing challenge, but the built environment has real power to respond. By improving efficiency, reducing pollution risks and getting involved in local catchment initiatives, organisations can protect both their operations and the environments they depend on.
This year, World Water Day is also shining a light on equality and the fact that millions of people still lack safe, reliable access to water. As we work to improve water use within buildings and organisations, it is worth remembering that fair and inclusive access is at the heart of global water security.
