Sustainable Drainage Systems (SuDs) seek to manage rainfall in a
way similar to natural processes and refer to a sequence of water
management practices and facilities designed to drain surface water
in a manner which is more sustainable than traditional pipe
Urbanisation, an ageing sewer network and an increased frequency
of intense rainfall events has contributed to an increased
risk of surface water flooding.
SuDs seek to mitigate the consequences of these impacts by:
- Managing surface water runoff in a more sustainable manner
- Reducing the risk of flooding
- Protecting and enhancing water quality
- Providing habitat for wildlife
- Providing amenity benefits
- Encouraging groundwater recharge.
Further information regarding SuDs can be found on the Susdrain
SuDs Approval Body
Among the new responsibilities assumed by the council
under the Flood and Water Management Act 2010 is the establishment
of an Approval Body to approve, inspect, adopt and maintain
Sustainable Drainage Systems (SuDs) for new and re-developments
exceeding one property, where they meet Government thresholds and
are built in accordance with National Standards.
Enactment of Schedule 3 of the Flood and Water
Management Act 2010 to enable adoption of SuDs has not yet
commenced. In December 2014, the Government announced an
alternative approach to delivering SuDs by strengthening
existing planning policy instead. Medway Council in it's remit as
Lead Local Flood Authority are now a statutory consultee for major
developments which have surface water implications. This new
responsibility will require LLFA's to provide comments in relation
to surface water drainage within 21 days.
Please refer to the Department for Food and Rural
Affairs (Defra) website for the latest consultation material
and latest developments in the legislation.
Medway Council, in partnership with other Local Authorities within
the South East and Aecom consultancy have produced a guidance
document for master planning sustainable drainage into
developments. We encourage the approaches outlined in the
guidance and urge developers to consider the opportunities and
constraints associated with the provision of sustainable drainage
as early in the planning process as possible.
