Water supply in Aberystwyth over the past few months is appalling, the water will randomly taste very very bad, almost sickening. Have got a new kettle and a water filter. In my opinion Welsh Water add far too much chlorine to the water and completely FAIL to monitor or address this issue effectively. Called to complain, was rudely told this is Normal. What a disgrace.
I can’t believe WW can charge such high amounts for water. They told me today 8th Aug 2009 that they charge £20 per person per month for water/sewage. Unbelievable!! Wales has the greatest rainfall in the entire world, they should be paying us for using it!!
The chlorine levels are way too high (I live in Haverfordwest in Pembrokeshire). When you run the tap it smells like a swimming pool. I have to buy mineral water in bulk as tap water makes me feel ill, even though I have tried filtering it. It’s costing me a lot of money. I have complained to the DWI and urge others to do the same.
I had a water meter fitted and had the bill, big shock, I got a leak, had to have a new water line from road to my sink to find it was not my problem as welsh water two goes of fitting the meter and it was their fault I had a leek and after all my drive has been ripped apart that say that’s the way the cookie crumble. Will I get any compensation for all the upset,
can anyone help?
We are having a meter installed and rang for advice (19:30 Friday evening). Excellent customer service. They answered phone straight away and were really polite and helpful.
Very good.

I’m sure that WW would provide water for free, but for the cost of pipes, treatments and energy to pump the water… There may be plenty of water, but this does not determine the cost!
Does anyone have any information on the Leakage Repair Scheme, I phoned WW as their Customer Information Leaflet states that they will endeavour to repair/replace one leak free of charge within three years at the same property. I’ve been waiting for a Call Back from WW for 4 days now as I need to speak to my nearest WW Contractors to speak about the amount of work to be done?
Can anyone help, we have a small shop with no water or toilet but welsh water are trying to charge us for water and sewage even though they know we have no water.
They say we must pay, when we said you would not come into our shop and pay for an item and not take it away with you they just said that’s the way it is and we must pay. Anyone else come across this?
Ask to be put on a meter it then puts the ball in their court.
Rang Welsh Water on Sat am – ok you can expect a bit of a wait – but spoke to helpful lady – advised I am leaving property – she was efficient – closed the account – only tiny complaint – they can’t refund any Direct debit overpayment back to my bank – they have to send a cheque. But service was good
