The increase in annual rainfall and residential flooding in the last 10 years has focused the minds of local authority's before granting planning permission approval.  


Planning permission and building regulation applications require site specific calculations to justify a design to  demonstrate rainwater and surface water removal compliance.  These measure will show how to mitigate against any additional flood risk from additional dwellings, outbuildings  and hard standings areas. 
The sustainable urban drainage systems (SUDS) are commonly provided in the form of  soakaway or attenuation tank designs. 

Please contact us if you require a SuDs design for planning permission or building regulation approval.
