Join water industry leaders, policymakers, and sustainability experts as they bring ambition, motivation, and innovation together to explore how a thriving, water-efficient future is possible.
There is no time to waste in driving further ambition for water efficiency, to help mitigate the climate emergency as well as adapt to it; plug the gap between supply and demand right across the UK; and drive behaviour change from the government, the water sector, and customers at home and at work. It’s been a challenging year for the UK water sector in many ways – including from media, public and political attention, pollution and flooding – and in some cases, focus being taken away from water efficiency. But nothing happens without water, so it’s more important than ever to keep the focus on water efficiency and increase ambition – it’s an essential and cost-effective tool to underpin our economic, social and environmental goals.
In this context, Waterwise will hold the 2025 annual Water Efficiency Conference, ‘No Time to Waste,’ from Monday, March 10th, until Thursday, March 13th, 2025. Four digital sessions will take place daily via Zoom, lasting between three and four hours from 9:30 a.m. to 1:00 p.m. each day.
The Waterwise Annual Conference has been the major national water efficiency event in the UK since 2007. 2025 will be another pivotal year, and at the conference, we will be taking a deep dive into ambition and mainstreaming water efficiency; motivation and inspiring a water-saving culture; thriving through growth and sustainable water use; and innovation in rainwater harvesting and re-use. As usual at Waterwise events, we will feature speakers and delegates from within and beyond the water sector to ensure a diverse and engaging conversation.
