What is SuDS?

The need for Sustainable urban Drainage Systems (SuDS)

Limited land space and the need for more housing and infrastructure means greater emphasis is being given to how we handle flood management. This of course impacts on watercourses and drainage systems with increased risk of localised flooding and pollution. To make matters worse, handling this added pressure of volume and water quality is fast becoming a developer’s responsibility rather than the local water authorities. So what’s the solution? The answer lies underground, not with the current drainage system, but with a new Sustainable Drainage System .

How do SuDS work?

Sustainable Drainage Systems combine a series of environmentally friendly elements to manage surface water run off as close to its origin as possible, before it enters the watercourse. These elements are made up of ponds, swales and infiltration strips that improve biodiversity, provide aesthetic and practical amenities whilst at the same time reducing the risk of flooding. Importantly, SuDS remove the need for any additional drainage systems, making them much more cost effective.

Supporting SuDs

As a company, we invest millions of pounds into researching and developing new systems and products. But we’re not the only people who are committed to sustainable drainage. Already many local authorities look favourably on developments that utilise SuDS. Planning Policy Statement note 25 requires new developments to incorporate sustainable drainage wherever possible. The Association of British Insurers is campaigning for a reduction in policy costs for schemes that incorporate SuDS.
