SuDS

Policy-Compliant Surface Water Management for Flood Resilience and Environmental Gain

Integrated Sustainable Drainage for Resilient Landscapes

Sustainable Drainage Systems, known as SuDS, are now a core element of responsible development across commercial and public landscapes. Designed to replicate natural water processes, SuDS manage rainfall at source, reducing flood risk, improving water quality, and supporting biodiversity while creating resilient, adaptable environments that respond effectively to changing climate conditions over time and across sites.

Practical SuDS Delivery Across Commercial and Public Realm Schemes

At Landcraft, we integrate SuDS into commercial and public realm schemes with a focus on practicality, compliance, and long-term performance. Our approach ensures outdoor spaces manage water efficiently while maintaining usability, visual quality, and manageable maintenance requirements, aligning with planning standards, environmental regulations, and the operational demands of modern developments across diverse sites and project scales.

Why SuDS Matter

Traditional drainage systems—based on rapid surface runoff and underground pipes—can overload networks during storms, contributing to flooding, pollution, and erosion.

SuDS address these issues through:

  • 1
    Slowing the flow of rainwater across surfaces
  • 2

    Infiltrating water into the ground or holding it for gradual release

  • 3

    Filtering pollutants through vegetation and substrate

  • 4

    Reducing pressure on local drainage infrastructure

They are increasingly required under planning policy and adopted by local authorities for developments ranging from housing schemes to business parks and civic spaces.

Core SuDS Features & Delivery

We design and install Sustainable Drainage Systems that meet site conditions, CIRIA C753 guidance, and local planning requirements.Core areas of focus include:

Typical SuDS elements include:

  • Swales for conveyance, filtration, and infiltration
  • Rain gardens for temporary storage and controlled discharge
  • Permeable paving for surface water infiltration
  • Infiltration basins and detention ponds for attenuation

Design and management priorities:

  • Integration with levels, planting, and materials
  • Safe, visible layouts for public environments
  • Exceedance capacity for extreme rainfall
  • Low-input planting and clear upkeep plans

Planning Drivers and Wider Benefits

SuDS are now a baseline requirement in modern development and form a key part of surface water strategies expected under national and local planning frameworks.

SuDS support development by:

  • Managing and retaining surface water on site
  • Enhancing water quality through natural treatment processes
  • Reducing reliance on conventional drainage systems

Common planning drivers include:

  • New residential and commercial developments
  • Flood-risk mitigation and retrofit schemes
  • Biodiversity Net Gain (BNG) requirements

Additional benefits include:

  • Enhanced biodiversity and microclimate improvement
  • Improved landscape quality and visual integration
  • Contribution to green infrastructure and ESG objectives
