Drainage Design

We provide drainage design for residential and commercial developments, supporting projects from planning through to construction.

Our designs cover foul and surface water drainage and are developed to be clear, compliant, and practical to implement on site.

What We Do

We design drainage systems that:

  • Meet planning and Building Regulations requirements
  • Comply with Local Authority and statutory guidance
  • Are practical and buildable
  • Integrate with the wider site layout

Our work ranges from simple domestic drainage layouts through to drainage strategies for residential development.

Our structural designs are prepared to support Building Control approval and provide clear information for use on site.

Surface Water Drainage

We design surface water drainage systems to manage runoff effectively and reduce flood risk.

This includes:

  • Soakaway and infiltration design
  • Attenuation systems and flow control
  • SuDS (Sustainable Drainage Systems)
  • Discharge to watercourses where appropriate

We assess site conditions and ground suitability to determine the most appropriate drainage solution.

We support clients looking for a structural engineer or civil engineer across the North East and nationwide, providing design solutions for extensions, developments, drainage, and planning requirements.

Foul Water Drainage

We design foul drainage systems to safely convey wastewater from buildings to the appropriate discharge point.

This includes:

Coordination with existing site infrastructure

Connection to existing public sewers

Septic tank and package treatment plant design

Pumped drainage systems where required

Supporting Planning and Approval

Drainage design is often required to support planning applications.

We can provide:

  • Drainage strategies for planning
  • Supporting information alongside Flood Risk Assessments
  • Advice on discharge hierarchy and site constraints

Our aim is to provide clear, proportionate information that supports planning approval without unnecessary complexity.


Working with Flood Risk Assessments

Drainage design is often closely linked to Flood Risk Assessments (FRAs).

Where both are required, we provide a coordinated approach to ensure:

  • Surface water management aligns with flood risk strategy
  • Discharge rates and storage volumes are appropriate
  • Planning requirements are addressed clearly
