Nicola Roberts (right), from Llangoed, Anglesey, was a happy and outgoing mum-of-three until she became one of 231 people affected by the bug after drinking tap water in November 2005.
Two years later Dwr Cymru/Welsh Water pleaded guilty to supplying water “unfit for human consumption.”
Dozens received compensation of between £1,300 and £5,000 after suffering symptoms like diarrhoea, stomach ache and fever for up to six weeks, others got more.
Nicola, who has just become a grandmother, is one of those still suffering six years on. She was initially offered £10,000 by Dr Cymru but refused it, claiming loss of earnings over six years. Her case was settled out of court before trial last week after Dwr Cymru improved its offer.
Nicola said: “They tested me and it was confirmed I had cryptosporidium. I was shocked. We weren’t told for about a month that the bug was in the water. It’s more embarrassing than anything else. I’m unable to go out anywhere. I’ve now got irritable bowel syndrome (IBS).”
