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.
