Sustainable Drainage Design (SuDS)
All developments in Cheshire East are required to have sustainable surface water drainage systems (SuDS).
Sustainable drainage systems control surface water run-off close to where it falls and copy natural drainage as closely as possible. This helps:
- reduce the risk of flooding
- reduce the harm caused by any floods that do happen
- remove pollutants at source
- give opportunities to combine water management with green space for the benefit of people and wildlife

Surface water management - major planning applications
The Council as a Lead Local Flood Authority, are a statutory consultee for surface water drainage on all major planning applications. To approve an application, we need to be satisfied that:
- the proposals are appropriate in relation to flood risk and pollution control
- there are clear arrangements in place for ongoing maintenance
A development counts as major if it involves one or more of the following:
- mineral extraction
- waste development
- more than 10 houses
- houses on a plot with an area of 0.5 hectares or more, if the number of houses isn't known
- floor space of a thousand square meters or more
- a site of 1 hectare or more
