Why is this guide needed?

The negative impacts of conventional drainage are now well understood.
Pipe drainage collects and conveys water away from where it rains, as quickly as possible, contributing to increased risk of flooding and contamination of water as well as the loss of our relationship with water and the benefits it can bring us all.
Sustainable Drainage (SuDS), is a way of managing rainfall that mimics the drainage processes found in nature and addresses the issues with conventional drainage.

Who this guide is intended for

In 2010 the Flood and Water Management Act proposed that SuDS should be used on most development and this was confirmed in a ministerial statement on 23 March 2015 introducing the ‘non statutory technical standards’ for SuDS.
The responsibility for ensuring that SuDS are designed and implemented to a satisfactory standard lies with the Local Planning Authority (LPA).
SuDS Designers need to meet these standards when submitting proposals to the LPA.

What the guide provides

This guide links the design of SuDS with the evaluation requirements of planning in a sequence that mirrors the SuDS design process.
This guide promotes the idea of integrating SuDS into the fabric of development using the available landscape spaces as well as the construction profile of buildings. This approach provides more interesting surroundings, cost benefits, and simplified future maintenance.
This guide begins by giving a background context for SuDS design. Next, the three accepted design stages are described: Concept Design, Outline Design and Detail Design. Subsequent chapters offer supporting information. It is intended that this guide will facilitate consultation, in order to achieve the best possible SuDS designs.
