Smart Rainwater. Better Living.
Modern rainwater harvesting designed for today’s homes.
RainWall is redefining domestic rainwater harvesting with beautifully designed, wall-mounted water storage systems that combine performance, sustainability and contemporary design.
Traditional water butts are bulky, unattractive and often impractical for modern homes. RainWall offers a smarter alternative—compact, slimline tanks that integrate seamlessly into your property while capturing and storing rainwater for everyday use.
Whether you’re flushing toilets, watering the garden or reducing your mains water consumption, RainWall makes sustainable living simple.
Every Flush Matters.
Every Flush Matters.
Every time you flush a toilet with mains water, you’re using clean, treated drinking water—water that has been carefully sourced, filtered, disinfected and pumped to your home.
Yet around 30% of the average household’s daily water use is for toilet flushing, where drinking-quality water simply isn’t required.
RainWall changes that.
Our systems collect and store natural rainwater, providing a sustainable supply for toilet flushing, garden irrigation, outdoor cleaning and other non-potable uses. Instead of sending perfectly good rainwater into the drains, RainWall puts it to work where it makes the biggest difference.
A Smarter Use of Water.
Fresh drinking water is one of our most precious natural resources. As the UK faces increasing pressure from population growth, climate change and more frequent periods of drought, using treated mains water for tasks that don’t require drinking-quality water is becoming increasingly difficult to justify.
RainWall helps homeowners reduce unnecessary demand on the public water supply while making better use of the rainfall that lands on their own roof every year.
It’s a simple change with a lasting impact.
Save Water. Save Money. Protect Tomorrow.
A typical RainWall 50 can replace thousands of litres of treated mains water every year by supplying a single toilet with harvested rainwater.
That means:
- Thousands of litres of drinking water saved every year
- Lower household water consumption
- Reduced demand on the UK’s water infrastructure
- Lower water bills for metered properties
- A more sustainable home for future generations
Financial savings are just one part of the story.
The real value is knowing that every flush, every watering can and every bucket of water is making better use of one of our most valuable natural resources.
