We have refilled the network and restored supplies to those areas affected by the burst water main (Flint, Holywell, Ffynnongroyw, Greenfield, Llanerch y Mor, Mostyn, Oakenholt, Talacre, Whitford and Mancot).

However we are aware of temporary discolouration issues affecting water supplies to households in Connah’s Quay. This has been caused as we have needed to move the water around the network to maintain supplies and will be temporary.

We are contacting those customers on our Priority Services Register and those households (text to mobile / landlines) which may be affected.

Some households may still be experiencing discoloured water, but this is temporary. We are flushing the system and customers can also run their taps for a short period to help it clear.

Customers can collect water supplies from our bottled water station at the Jade Jones Pavilion in Flint (CH6 5ER) which remains open as a precaution.

More information is available here. We will also continue to provide updates on In Your Area and on our social media channels.

Our Vulnerable Customer Community Team have been out and about raising awareness of our support services and schemes, at a variety of events across Wales this month. 

Being in the community allows us to support those who may be digitally excluded, or those who may have disabilities or medical conditions preventing them accessing our support via traditional communication channels. 

Some of our customers may let us know, how hard they find it to communicate via the phone due to anxiety or worry. Being in the community helps us to reach those customers to access the support they may desperately need.
