A Complete Guide To Sustainable Drainage Systems (SuDS) & SuDS Reports

By Sadia Luckett on Oct 8, 2021 2:15:03 PM

Sustainable Urban Drainage Systems (SuDS) manage surface water run-off as close to its source as possible. This reduces the potential impacts and risks of surface water flooding, fluvial and tidal flooding- by reducing the peak flows entering the rivers, the sea and the sewers.

Whether you are a property developer, architect, land owner or planning consultant this complete guide to SuDS and SuDS design and reports sets out to teach you all you need-to-know about how they work and how they can affect your proposed development.

In certain situations, a Sustainable Urban Drainage System (SuDS) assessment is a compulsory requirement at planning application stage. In England, from April 2015, it became compulsory for SuDS to be considered in planning applications for major developments, and Lead Local Flood Authorities quite often request SuDS at planning application stage for minor developments also.

Unfortunately, a lot of the information in this area can be full of jargon or disconnected. Let’s address that, by taking a look at the key information regarding SuDS in a simple and clearly approached way.

What Is Surface Water Flooding?

By Sadia Luckett on Aug 24, 2021 10:16:33 AM

Simply put, surface water flooding occurs when the volume of rainwater falling is unable to drain away through existing drainage systems or by filtering into the ground. As a result, the water lies on the ground and may begin to flow – causing localised floods, which can affect your developments.

Typically, surface water flooding is caused by the amount of rainfall and the high speed at which it hits the ground. This causes a build-up that prevents the existing drainage systems from draining it.

Surface water flood events usually have localised effects, therefore only impacting properties in a close proximity to the resulting floods. In these instances, it may only affect those properties and the surrounding areas for a short period of time.

However, due to the sporadic and intense nature of these surface water flood events, the damage can be extensive and affect huge areas, being in-situ for prolonged periods of time.

So we know that surface water flooding can be hugely disruptive to your new development(s).

Now let’s see how it could affect you and your future planning applications and what you can do to prepare for it.
