Rainwater Harvesting for New Builds: SuDS and SAB Compliance Made Simple

Why Rainwater Harvesting Matters for New Builds

As modern construction evolves, sustainability and compliance have become essential for new builds. Developers in the UK, and particularly in Wales, are increasingly required to integrate Sustainable Drainage Systems (SuDS) and meet Standards for Approval Bodies (SAB) compliance for surface water management.

Rainwater harvesting is no longer optional  it’s a practical solution that ensures your build is environmentally responsible, cost-effective, and compliant with local regulations.

Understanding SuDS and SAB Compliance

SuDS (Sustainable Drainage Systems):


SuDS are designed to manage surface water sustainably, reducing flood risk and improving water quality. Rainwater harvesting systems contribute by:

  • Collecting rainwater from roofs and hard surfaces

  • Storing water for non-potable uses like garden irrigation or toilet flushing

  • Reducing pressure on public drainage systems

SAB Compliance in Wales:
In Wales, all new developments must meet SAB approval under the Flood and Water Management Act. Proper rainwater management through compliant harvesting systems helps developers gain approval quickly, avoid fines, and demonstrate commitment to sustainable building practices.
