Bespoke rain gardens for Slough’s communities

Through Project Sponge, and in close consultation with local communities, BluWater Solutions supported the design and delivery of rain gardens and sustainable drainage systems (SuDS) planters across three community sites in Slough.

Requirement

The project needed to capture and slow rainwater in everyday community spaces, helping to manage surface water while supporting biodiversity and water-quality objectives. The brief also called for welcoming places where people could enjoy and connect with nature.

Challenges

Each site presented different constraints, including available space, existing drainage routes, access and budget. Unexpected below-ground obstacles required changes during construction. Designs also needed to reflect each community’s identity and priorities, while keeping ongoing maintenance straightforward.

Solution

Working with specialist partners and local communities, BluWater Solutions helped deliver a tailored approach at each site:

  • Pakistan Welfare Association: Two rain gardens combining Persian-Islamic design influences, bespoke fabricated features and planting selected to support pollinators.
  • James Elliman Academy: A rain garden with a visible water channel and stepping stones, making rainwater management part of the learning landscape.
  • Ramgarhia Gurdwara: Four SuDS & BNG Planters fitted alongside an existing raised-bed area.

BluWater Solutions combined in-house design and fabrication with specialist growing media and planting suited to dry conditions and occasional heavy rainfall. A simple seasonal maintenance approach, alongside community involvement in design and planting, encouraged local ownership and ongoing care.

“The rain garden will provide a beautiful outdoor space for our community while encouraging people of all ages to connect with nature.”

“This is another shining showcase of when community action, empowerment and technical expertise comes together… we hope the rain gardens bring a feeling of safety (from flooding), calmness and connection, long into the future.”

Outcome

Across three distinct community settings, the project brought together rain gardens, SuDS units, specialist growing materials and locally shaped design. The installations are designed to help manage surface water while supporting biodiversity, water-quality objectives and more enjoyable community spaces. BluWater Solutions’ contribution demonstrates what can be achieved by combining technical design and practical delivery expertise with cultural identity, learning and community participation.
