Culvert Information for Cynon Valley

Critical Drainage “Hotspots”

Rhondda Cynon Taf CBC provided a report “Arrangements during Flood Incidents” (November

2007) which identified 790 sites through the Rhondda, Cynon and Taf areas. This detailed the culverts throughout the area and identified the location, owner and district within which these were located. Furthermore, ‘priority culverts’ were identified which are culverts with known blockage and / or flooding issues and therefore required regular maintenance to ensure that they operated as efficiently as possible. 

The list was transferred into an electronic spreadsheet and from this the priority culverts extracted. Because the precise location of the priority culverts was not known, the culverts were groped into specific towns or villages, and within these the number of priority culverts identified. In addition to the priority culverts identified above Rhonda Cynon Taf have identified further locations of culverts, which are considered to pose the greatest flood risk in the event of blockage.

These have also been identified within GIS.

Critical Drainage “Hotspots”

• There are approximately 790 culverted watercourses and / or drainage channels within the study area.

• 511 of the culverts have been classified as “Priority Culverts” by Rhondda Cynon Taf

CBC;

• 317 of the “priority culverts” have been identified as being privately owned;

• 172 of the “priority culverts” are owned and or maintained by Rhondda Cynon Taf CBC;

• No ownership could be identified for 22 of the “priority culverts”

• 48 communities / towns are potentially at risk of flooding from the critical drainage issues

Identified.

 

Increased likelihood of blockages

Compared with an open watercourse there is an increased risk of blockage once a culvert is installed. If the blockage is within the culvert, there is much greater difficulty in removing it.

For these reasons many culverts have screens installed at their upstream end. These screens themselves are often prone to blockage and require frequent clearance and robust emergency procedures to ensure that they do not in themselves cause flooding.
