Nant Gwawr Flood Alleviation Scheme

232 residential properties in the Aberaman area will benefit from a project to help protect them from flooding.

Thanks to support from the Welsh Government’s Flood Risk Management Grant, European Regional Development Fund and Rhondda Cynon Taf Council capital funds is a scheme will be implemented to alleviate historical flooding issues centred around the Cardiff Road Culvert and the down stream watercourses. 

The project will comprise the renewal of the roof and bottom (invert) of the Cardiff Road Culvert and new inlet and outlet configurations.  Downstream watercourse works will entail increasing the capacity of the watercourses together with erosion/scour protection increasing resilience too damage during heavy storms.  Some existing structures will be modified to enable a more free flowing system with overflow systems also used at critical areas to provide resilience to blockage.  Warning systems will be installed on the new system to provide maintenance teams with advanced warnings of potential blockage.

Risk of localised flooding continues to be an issue during and after the project and RCT CBC Flood Risk Management team continues to work with our partners in the community and the Waste Management and Streetcare divisions of the Council to minimise that risk. 

However, the risk of flooding significantly increases where there is illegal tipping of rubbish in and around the streams and culverts.  We therefore request that the general public only uses official and legal means for disposal of their rubbish.

Cardiff Road Highway Improvements

The Council is proposing Highway Improvement works to Cardiff Road, Aberaman.

It is intended that the works will run in parallel with the flood alleviation scheme to minimise extended disruption to the local area.

The project will comprise carriageway widening between the junctions with Abergwawr Street and Curre Street, traffic management and extensive re-surfacing of the carriageway between Sunnybank Street, junction of Lewis Street and Mount Hill Street.

A brief overview plan of the project can be accessed via this page together with pictures chronicling the project as it progresses.  A “live” project update can be found below.
