Introduction
Sustainable Urban Drainage Systems (SUDS) is a relatively new approach to the management of rainfall runoff on development sites. It eliminates the problems associated with conventional drainage by utilising a range of design techniques that ensure runoff is collected, stored and cleaned prior to its controlled release to the environment.

The principle aim of SUDS is to minimise the impact of surface water runoff on the natural environment through flood control, pollution prevention and improved public amenity.

Sustainable Drainage is advocated by the Environment Agency (EA Policy no EAS/2/1/1), increasingly required by Local Authorities in the planning process and recommended in Planning Policy Guidance (PPG 25) - Development and Flood Risk.

Sustainable Drainage is rapidly developing as a distinct discipline, but it is frequently misunderstood by the construction industry and can be poorly interpreted by the design profession.

Concept
Through our related company EPG Clear, we provide a comprehensive design and management consultancy comprising acknowledged experts in the field of Sustainable Drainage.

The design team can ensure that project-specific requirements are achieved through a combination of technical expertise, practical application of geotechnical engineering, drainage assessment and our long term commitment to ongoing research into the development of SUDS techniques.

Our specialist hydraulic modelling capability can be used to fully assesses drainage design and optimise the SUDS solutions for large and complex projects.
