SuDS Design

At Such Salinger Peters, we provide Sustainable Drainage Systems (SuDS) design to support residential, commercial and infrastructure development across the UK.

Effective surface water management is essential for successful development. Sustainable Drainage Systems help manage rainfall in a way that reduces flood risk, improves water quality and supports environmentally responsible design.

Our team delivers practical, compliant SuDS solutions that integrate seamlessly into wider drainage and development strategies.

Sustainable Drainage Systems (SuDS) are drainage solutions designed to manage rainwater as close as possible to where it falls, mimicking natural drainage processes.

Rather than simply directing water away as quickly as possible, SuDS aim to:

• Slow surface water runoff
• Reduce flood risk
• Improve water quality
• Support biodiversity
• Enhance site sustainability
• Protect existing drainage infrastructure

SuDS are increasingly a key requirement for planning approval and modern development.

We provide a full range of SuDS design and consultancy services, including:

• Surface Water Management Strategies
• SuDS Feasibility Assessments
• Permeable Paving Design
• Soakaway Design & Infiltration Advice
• Swale Design
• Attenuation Tank Design
• Rain Garden Design Advice
• Flow Control & Discharge Solutions
• Drainage Layout Drawings
• Hydraulic Design Support
• Planning Submission Support
• Integrated Drainage Strategy Design
• Organise, supervise and report BRE 365 Soakaway Tests

Well-designed Sustainable Drainage Systems offer significant long-term benefits.

SuDS can help to:

• Reduce the risk of surface water flooding
• Prevent overwhelming existing drainage systems
• Improve the quality of discharged water
• Support planning policy compliance
• Create greener, more attractive developments
• Increase environmental sustainability
• Support climate resilience
• Deliver practical long-term drainage solutions

Modern drainage design is no longer just about moving water away; it’s about managing it responsibly.

SSP can provide comprehensive support with BRE 365 soakaway testing, helping to organise, supervise and report on testing undertaken to assess the suitability of ground conditions for infiltration drainage. We can coordinate the testing process, oversee works on site and review the results to provide clear, professional reporting. The findings can then be used to inform the design of appropriate and effective drainage and SuDS solutions for your development.

Depending on the site and project requirements, SuDS solutions may include:

Permeable Paving – Allows water to infiltrate through surfaces naturally.

Soakaways – Encourages infiltration into the ground where site conditions allow.

Swales – Shallow vegetated channels designed to convey and manage runoff.

Attenuation Systems – Temporary storage solutions that control discharge rates.

Rain Gardens – Landscaped drainage features that manage runoff sustainably.

Flow Control Devices – Regulate discharge into drainage networks. 

Each site requires a tailored solution based on technical, environmental and planning constraints.

Sustainable drainage is often a critical planning consideration.

We support clients in meeting drainage requirements associated with:

• Planning applications
• Local Authority drainage policies
• Environmental considerations
• Surface water management requirements
• Sustainable development expectations
• Flood mitigation strategies

Our practical approach helps ensure SuDS design aligns with wider planning and engineering requirements.

SuDS design works most effective when considered alongside wider drainage and flood risk strategies.
