Background to Treforest

February 2020 was the wettest February on record according to the Met Office. Just a week after Storm Ciara, Storm Dennis resulted in substantial and intense rainfall with significant impacts on river flows, river levels and flooding across South Wales. The severe flood event affected much of Wales, and in particular from the River Taff at Pontypridd that impacted the Treforest Industrial Estate area.

In Pontypridd, the River Taff reached its highest level since records began in 1968. Peak flow passing through Pontypridd was estimated at 805 m3/s, enough to fill an Olympic size swimming pool in just over three seconds. The river level was 78cm higher than the previous record-level set during the 1979 floods

NRW flood defence embankments exist along the River Taff in the vicinity of Treforest Estate.  These are assessed by NRW to provide a standard of protection of between 1:75 and 1:100 year (so affording protection from a flood with a chance of occurring of between 1.3% and 1% in any year).

However, the Storm Dennis flood event on the River Taff has been assessed by NRW to have equated to approximately a 1:200 year event (0.5% AEP). As a result, the river levels exceeded the design level and the flood defence embankments were over-topped.

NRW have stated their evidence suggests the flood defences did not fail, they were just overwhelmed by the volume of water exceeding their design standard.  Further detailed post-flood investigations continue to be managed by NRW which will identify if there are any localised issues to consider

A significant number of properties were protected by NRW flood defences and the flood warnings helped many people to protect themselves, their families and their properties, as well as assist partner organisations with their response. However over 3,000 properties did unfortunately flood across Wales. There is a flood warning service that covers the Treforest Estate area but some of the Severe Flood Warnings on the River Taff were either missed or issued later than the target time, due to the extremely rapid rise in levels.

There is community wide protection in place in the form of flood defence embankments and a thorough review of the entire Lower Taff has been instigated to consider in detail the likely causes of flooding and identify where action may be needed in the future.

At an individual property owner level the focus is therefore very much on preparing for residual flood risk and improved flood resilience through local site works and emergency response and evacuation plans.
