Sustainable Urban Drainage Systems (SuDS) are a sequence of water management practices and facilities designed to drain surface water in a manner that will provide a more sustainable approach than the conventional practice of routing run-off through a pipe to a watercourse.

The aim of SuDS is to mimic the natural surface water drainage process. For new developments this can be achieved through the inclusion of features such as soakaways, infiltration basins, swales, permeable pavements, filter strips and balancing ponds.

New developments often replace absorbent land with significant areas (buildings, roads, driveways, etc.) which are impermeable to rainwater and which, during times of high rainfall, cause runoff leading to flooding.

The devastating floods of 2007, exacerbated in many cases by inadequate storm water controls, have placed renewed emphasis on the need for adequate and sustainable storm water management.

The government’s National Planning Policy framework (NPPF) requires that planning applications for new developments using SuDS are given priority.
