Penyffordd Monsoon

Half an hour of full pelt rain. Coming in places here I've never seen before. Cue buckets.
In Penymynydd Rd the ditch was piped years ago. It runs under Chester Rd then down into the stream.
At the moment there are 1000's of gallons pouring out the manhole for the drainage. Its running across Chester Rd and into Ken's garden.

Spoke to a utility man some time ago who opined that before the pipe goes into the ditch the pipe diameter reduces there by causing a back pressure up to Penymynydd Rd

Any reduction of pipe diameter shouldnt have been allowed if it has happened.

Usual nutters on the road who dont see the need to slow down.
