What is a Rain Garden?

Nature-based solutions that start at your doorstep.

Rain gardens are living systems that harness the power of nature to solve real-world problems. They slow floodwater, filter pollutants, cool the land, capture carbon, and create micro-habitats that support biodiversity. All while improving water quality and transforming grey space into green space.

Cleaner Seas Project works with individuals, businesses, schools and councils to co-create rain gardens that are both beautiful and functional nature-based solutions that deliver long-term value for money.

We see rain gardens as part of a bigger vision — one that blends environmental regeneration with social impact. That’s why we’re actively bringing rain garden projects to communities from Bude to London, Cardiff to Glasgow — including areas where green infrastructure can support wellbeing, education and opportunity.

🌿 The Benefits of Rain Gardens:

• Prevent urban flooding

• Filter out pollutants before they reach rivers and seas

• Support pollinators and wildlife (biodiversity gain)

• Cool the land and reduce urban heat

• Sequester carbon naturally

• Improve water quality at the source

• Provide green, sensory-rich community spaces

• Require minimal maintenance once established

Ways You Can Get Involved:

• Volunteer on a rain garden build or community planting day

• Donate to help fund materials, plants and tools

• Partner with us to bring rain gardens to your school, street or site

• Sponsor a rain garden in your name or on behalf of your business

• Collaborate with us on research, design or delivery

We believe in doing more good — not just less harm. Rain gardens are a simple, scalable way to bring that vision to life.
