SUDS
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 Planning Policy Statement ‘Development and Flood Risk’ (PPS25) requires that planning applications for new developments using SUDS are given priority.

The Benefits
A professional Sustainable Urban Drainage System prepared by Cole Easdon Consultants will:
▪ Provide developers with the SUDS plan
needed by Local Planning Authorities to
prioritise proposed developments.
▪ Enable the sustainable management of
surface water drainage.
▪ Reduce the risk of flooding to the
development and the surrounding area.
▪ Improve the quality of downstream water.
▪ Incorporate features, such as permanent
ponds, which can improve local amenity and
provide an environment to support
bio-diversity.

How We Can Help
As experts in water management we provide some or all of the following services to help our clients deliver effective Sustainable Urban Drainage Systems (SUDS):
▪ The provision of SUDS advice and design.
▪ Computer modelling of drainage networks
including sewers and watercourses using
WINDES software.
▪ Soil infiltration testing to determine
soakaway drainage potential.
▪ Technical assistance to understand surface
water flooding (e.g. drainage exceedance
modelling to determine flood volumes,
velocities and mapping of flood flow routes).
▪ Preparation of PPS25 compliant sustainable
drainage strategies.
