SUDS - SUSTAINABLE DRAINAGE SYSTEMS

Surface water drainage systems that take account of water quantity, quality and amenity issues are referred to as Sustainable Drainage Systems (SuDS).

SuDS are a sequence of management practices, control structures and strategies designed to efficiently and sustainably drain surface water, while minimising pollution and managing the impact on water quality of local water bodies.

These systems are deemed more sustainable than conventional drainage methods because they can manage surface water run-off volumes and flow rates which reduce the impact of urbanisation on flooding.

They also protect or enhance water quality and are sympathetic to the environmental setting and the needs of the local community.
They also provide and enhance wildlife habitats in urban watercourses and encourage natural groundwater recharge.

SuDS are made up of the following methods to enable management of surface water run-off.

• Filter strips and swales
• Permeable surfaces and filter drains
• Infiltration devices: soakaways, porous paviors etc
• Basins, ponds and lakes
• These controls should be located as close as possible to where the rainwater falls, providing attenuation for the run-off.

The above are used together with good management and maintenance of the site to manage flooding and pollution risks.

At A.L.I. Building Design Ltd we can design the most appropriate and cost effective system for your development which complies fully with SuDS requirements.

DESIGN SERVICE INCLUDES:
Liaison with all Local Authorities, Water Authorities and Environment Agencies to ensure that the system design complies with policy and requirements.
