Home Environment and planning Flooding and drainage Surface water drainage for developments Sustainable drainage systems (SuDS) are used to reduce the risk of flooding caused by surface water drainage. SuDS try to copy the way that water drains in nature, instead of relying solely on traditional piped drainage. On 15th April 2015 Leicestershire County Council as the Lead Local Flood Authority (LLFA) became a statutory consultee to the planning process. We are now responsible for reviewing the surface water drainage systems for all major development applications. Using sustainable drainage systems is important in ensuring that developments do not increase the risk of flooding. As a statutory consultee we are required to assess applications in line with the current planning legislation.
