Sustainable Drainage Statements (SuDS)

Expert SuDS Reports and Drainage Impact Assessments for UK Planning Applications

At Elite Ecology, we provide professionally prepared Sustainable Drainage Statements (SuDS) and Drainage Impact Assessments to support planning applications across the UK. These reports are a crucial requirement for many developments, helping to manage surface water runoff, reduce flood risk, and ensure compliance with national and local planning policy.

Whether you’re developing a housing scheme, commercial site, or industrial project, our tailored drainage strategies ensure your proposal aligns with both sustainability standards and regulatory requirements.

What Is a Sustainable Drainage Statement?

A Sustainable Drainage Statement (SuDS Statement) is a planning document that explains how surface water will be managed on a development site. It outlines how your proposed drainage system will:

Control the quantity and flow of surface water runoff
Improve water quality before discharge
Protect nearby watercourses and habitats
Reduce the risk of localised and downstream flooding
Conform to planning policy and SuDS principles

The aim is to mimic natural drainage processes as closely as possible, using features like permeable surfaces, swales, green roofs, attenuation basins, and soakaways.

When Is a SuDS Report Required?

A SuDS report or drainage strategy is usually required when:

Your development consists of 10 or more dwellings or is the commercial/industrial equivalent
The site lies within Flood Zones 2 or 3
The area is identified as being at risk from surface water flooding
Local planning authorities request a Drainage Impact Assessment
You’re submitting a major planning application or working in a critical drainage area

If you're unsure whether your project needs a SuDS report, Elite Ecology can assess your site and advise on the necessary documentation.

What’s Included in Our Sustainable Drainage Strategy?

Each report is tailored to the specific conditions of your development site. A typical SuDS statement or drainage strategy from Elite Ecology includes:

Site analysis – including topography, soil type, and existing drainage infrastructure
Assessment of flood risk and runoff sources
Design principles for proposed SuDS features
Surface water discharge calculations
Drainage layout and flow paths
Alignment with local and national planning policy (e.g., the National Planning Policy Framework and local SuDS guidance)
Recommendations for implementation and maintenance

We provide clear, compliant reports ready for submission to your Local Planning Authority.

Why Are SuDS Important for Planning?

Sustainable drainage is now a key part of national planning policy, with local authorities requiring developers to demonstrate how surface water will be managed on-site and post-development. A well-designed SuDS system can:

Help secure planning approval
Reduce long-term maintenance and flooding risk
Improve the environmental performance of your development
Enhance amenity and biodiversity through green infrastructure
Meet conditions for Biodiversity Net Gain (BNG) and sustainable development goals

By engaging Elite Ecology early in your planning process, we can help you design a strategy that works for both the environment and your bottom line.
