Updated: 22:00 18 January 2025

Our network has been refilling overnight and supplies are being restored to some customers. Help and support after an incident.


Bottled water is available at Llandudno West Shore Car Park (LL30 2BG), Bodlondeb, former Council office site (LL32 8DU), Parc Eirias (LL29 7SP) and Zip World Conwy (LL32 8QE).

 

Water supplies will still not be fully restored to all affected customers for up to 48 hours. This is a high-pressure water main, and we are at a very precarious stage of the process. We need to refill the water main and wider water network very carefully to avoid further bursts.

The network is nearly 900km long and includes 13 underground storage tanks, with our single biggest storage tank the size of 9 Olympic size swimming pools.

Different communities within the network area will have their water supply restored at different times, as the network fills again.

Discoloured water from your taps is normal after a supply interruption. This is usually temporary and disappears once the network settles.

We also ask that customers check their taps to ensure that they are closed to help conserve supplies as we refill the network

To recognise the inconvenience being experienced by customers whose supplies have disrupted, each eligible household will be paid £30 in compensation for every 12 hours their supplies have been affected. This will automatically be paid to customers in their bank accounts. Cheques will be issued over the coming weeks to customers who do not have registered a bank account with us. Business customers will be paid £75 in compensation for every 12 hours their supplies have been affected but businesses will also be able to submit separate claims for additional loss of income. Details have been published here for business customers who are being impacted by this incident. 

Customers can get the latest information on in your area or follow us on our social media channels.

After an incident


Following an incident, you may have some questions about your water supply returning or what happens next if you need to make a claim.

Help and Advice

Your supply may look different to normal for a short period of time after an incident.

Discoloured water

Discoloured water which is yellow, orange, brown cloudy or black is caused by particles of iron or manganese, which have usually come from cast iron water mains, and have settled over time in the network.

As we return water through the system and the pressure increases, this can increase the water flow and can stir up the sediment.

Discolouration is usually short term and if you run your taps for a few minutes then this should clear.

Cloudy Water

Tiny air bubbles can cause your water to look cloudy or discoloured. The air bubbles are quite harmless and will quickly clear.

If this happens, try leaving it in a glass of water for a few minutes to see if it clears.

Cloudy Water is usually short term and if you run your taps for a few minutes then this should clear.

Frequently asked questions

Low water pressure

Sometimes the water pressure can take a while to build up again following an incident.

The pressure might take several hours to fully return and depends on where you live. For example, customers at the top of a hill are likely to take longer to get full pressure than those at the bottom.

The water might also splutter out of your taps when it first comes back on. This should clear if you run your taps for a couple of minutes.
