Rhondda Cynon Taf is vulnerable to flooding from several sources but particularly from local sources which include surface water, ordinary watercourses, and groundwater flooding. It is important to understand the different types of flood risk and who is responsible for managing it – whether this is a Risk Management Authority or the land / property owner.
The below table summarises the types of flooding and who to contact.

Flooding is a natural process, and we cannot prevent flooding, but we aim to alleviate the risk of flooding in our communities. The key to limiting the impact of flooding to property, land and businesses in our communities is the preparedness of the individual. You can learn how to be more prepared for flooding on our dedicated Flood Awareness and Preparedness pages.
