SuDS Report: Why You Need One for Your Development Project
One of the most common questions we receive is: “I’m replacing an existing building with a similar-sized one—why do I still need a SuDS report?”
If you’re applying for planning permission, you’ve likely encountered several required surveys and reports. A SuDS report (Sustainable Urban Drainage Systems report) is one of them, and while it may seem unnecessary for a like-for-like replacement, it plays a crucial role in flood risk management.
What Is a SuDS Report and Why Is It Required?
A SuDS report is designed to ensure that any new development manages surface water runoff effectively, reducing the risk of flooding both on-site and in surrounding areas. You may assume that since your new building has the same footprint as the previous one, runoff will remain unchanged. However, the issue lies in the existing drainage system’s capacity.
Many drainage systems, including surface water pipes, rivers, and watercourses, are already under strain due to urbanisation and climate change. Extreme weather events are becoming more frequent, increasing flood risks. To mitigate this, new developments must incorporate Sustainable Urban Drainage Systems (SuDS) to manage excess water effectively.
This is why local authorities require a SuDS report as part of your planning application or to discharge planning conditions. Without one, your project may face delays or rejection due to concerns about flood risk and drainage compliance.
How Nimbus Delivers Cost-Effective SuDS Reports
At Nimbus, we understand that project budgets can be tight. That’s why we provide cost-effective and practical SuDS reports, ensuring your development meets planning requirements without unnecessary expense.
Our SuDS reports outline the necessary drainage strategies for your site, helping you understand the key elements needed to gain planning approval.
Additional Surveys for SuDS Reports
In some cases, further assessments are required, such as:
- BRE365 Infiltration Tests (Percolation Tests) – To determine how well the soil absorbs water.
- CCTV Drainage Surveys – To inspect existing drainage conditions.
Since we handle these surveys in-house, we can efficiently coordinate with site teams to avoid delays in your SuDS report submission.
