Systemau Draenio Trefol Cynaliadwy (SDTC)

Sustainable drainage systems, commonly referred to as SuDS, manage the volume and rate of surface run off to maximize environmental benefits.     

Sustainable draining systems mimic natural drainage, so water runs off close to the surface and close to its source.  

All new developments of more than one house, or where the construction area is of 100m2 or more, require sustainable drainage.  

These drainage systems must be approved by the local Sustainable Drainage Approval Body (SAB) before construction work begins.  

The SAB will have a duty to approve and adopt compliant systems, where the system serves more than one property. 

Caerphilly Council provides pre-application advice and technical approval of SuDs applications on behalf of Torfaen Council.
