Water Reuse Week is the UK’s official national awareness week dedicated to water reuse technologies. Taking place from 14–20 September 2026, the week brings together businesses, schools, communities, water companies, policymakers and individuals to champion practical solutions that help save one of our most precious resources.
Now in its third consecutive year, Water Reuse Week has firmly established itself as a key event in the UK’s water efficiency calendar. Throughout the week, a packed programme of activities, events and educational initiatives will take place across the country, all designed to inspire action and raise awareness of the vital role that rainwater harvesting and greywater recycling can play in creating a more sustainable future.
Originally launched by Stormsaver in 2024, the campaign quickly gained national recognition. Following its success, Water Reuse Week has grown into an annual industry event and is now proudly organised by the UK Water Reuse Association.
Find out more below about how you can get involved and some of the very exciting events which are occurring, including Waterwise’s Water Reuse Summit.
Get involved – Every drop counts
Whether you’re at home, in school or at work, there are plenty of simple ways to take part in Water Reuse Week. Small actions really do make a big difference.
Here are a few easy ways you can start reusing water today:
- Save your lukewarm tap water – Instead of letting water run until it’s cold, collect it in a jug for drinking later or reuse it around the home.
- Empty refillable bottles – Don’t pour leftover water down the sink. Collect it during the week and use it to water your plants.
- Reuse leftover kettle water – Once cooled, unused boiled water is perfect for watering plants.
- Collect rainwater – Place buckets or water butts outside and use harvested rainwater in your garden.
- Reuse condenser dryer water – Water collected from condenser tumble dryers can be used for many household tasks or watering suitable plants.
- Save cooking water – Once cooled, water used to boil vegetables or pasta can be reused in the garden.

Kicking off this year’s programme, the Water Reuse Week Summit will bring together influential voices from across government, development, water companies and the built environment to tackle one of the UK’s biggest water challenges – accelerating the adoption of water reuse.
The summit will take place at The Building Centre in London and explore the policy, regulatory and operational barriers currently limiting wider uptake, while identifying practical actions that can drive meaningful change.
We’re delighted to welcome an outstanding line-up of speakers, including:

- Michael Farnsworth, CEO, Stormsaver
Following the summit, we’ll publish a comprehensive report featuring key insights, recommendations and outcomes from the day’s discussions.
Live Site Visits
Throughout Water Reuse Week, Stormsaver will be hosting a series of exclusive site visits across the UK.
Designers, developers, water companies and industry professionals will have the opportunity to see rainwater harvesting and greywater recycling systems in action, with hands-on demonstrations, expert guidance and practical learning sessions showcasing how water reuse is being successfully implemented in real-world projects.
Inspiring the Next Generation
Water Reuse Week is also about inspiring future generations.
Our Managing Director, Lisa Craven, will be visiting Lowes Wong Junior School in Southwell, Nottinghamshire, to deliver an interactive educational session exploring the importance of water reuse, water conservation and sustainable thinking.
By engaging young people today, we’re helping to build a generation that values and protects water for tomorrow.
