We empower individuals, communities, organisations and businesses to make impact through collective action, collaboration and capturing rain together. Find out more or work with us.
We help households capture rainwater. But why is this important?
Weather is always a go to topic of conversation for us Brits, it’s either too hot, raining non-stop or constantly grey. (Or somehow a mixture all at once?!)
Despite our mixed feelings, tricky relationship with the weather, and the assumption that it rains non-stop in the UK, we face lots of challenges when it comes to our water resources and rainwater, including surface water flooding, sewer spills and water stress.
Rainwater is a precious resource - although it might not feel like it when you’re walking to work in drizzly Monday morning.
But ultimately, we need rainwater to survive. Think about how you use water every day, for drinking, washing, cooking, watering plants and more! We use an average of 145 litres of water per day per person in the UK which is equivalent too:
Because of this rainwater needs to be “managed”. It refills our rivers, groundwater and aquifers providing us with water at the turn of a tap. That’s without mentioning it’s importance in food production, industry and many processes.
Not only do we need to take care of rainwater as a resource, this plays a key role in mitigating the impact of surface water flooding, sewer spills and ensuring a healthy environment and ecosystem for future generations.
Our mission is to empower individuals, communities and organisations to harness the power of the rain by capturing this precious resource on a larger scale and more data-driven way than ever before.
Surface water flooding is disruptive, dangerous and damaging.
When it rains heavily, hard surfaces like roads, rooftops, and patios stop water from soaking into the ground. Instead, all that water runs off quickly, overwhelming drains and causing local flooding. It can leave streets, gardens, and even homes under water. And with climate change bringing more intense rainfall, it's happening more often
These issues will impact us all.
No one entity, be it individual, government, water company, local authority or business can solve these issues alone.
But the good news is: together we can make a difference.
One person or one household alone cannot make a difference, but through collective action our individual contributions will make a difference.
We’ve already helped communities slow the flow of water into drainage systems by working with local authorities, water companies and other organisations to install rainwater capture devices, like water butts and rain planters.
Whilst these seemingly small and simple water butts may seem insignificant alone, imagine the impact of every street capturing the rainwater from their roof top? This helps to:
Increasing Urban Areas
More towns and cities mean more buildings, roads, and car parks - and less open land for rain to soak into. As cities grow, all that extra hard ground makes managing rainwater way trickier
Increasing Hard Surfaces
Concrete, tarmac, and rooftops don’t let water sink in like soil does. The more hard surfaces we create, the faster rainwater rushes off, piling pressure on drains and waterways. Did you know, water can travel 50% faster across a hard surface like concrete compared to a more natural surface?
Increasing Population
More people means more homes, gardens, and water use. It also means our water systems get busier, and there’s more demand on already stretched resources.
Climate Change
Weather patterns are shifting - with heavier storms and longer dry spells. That means flooding happens more often, but droughts are also becoming a bigger worry.
Ageing Infrastructure
A lot of our pipes, drains, and treatment plants were built decades ago - they weren’t designed for today’s challenges. Old infrastructure struggles to cope, leading to leaks, spills, and floods.
Housing Developments
New housing is needed, but building on green spaces reduces places where water can soak away naturally. Without smart planning, new developments can add to flooding and sewer problems.
