Welsh Water

Experts investigating a north Wales stomach bug outbreak which has

struck 123 people say untreated sewage may have entered the water

supply.

October's heavy rain could have caused a septic tank to fail allowing

sewage into Cwellyn reservoir, said Dr Mark Walker of the outbreak

control team.

Meanwhile, Welsh Water said customers might receive compensation for

weeks of having to boil their drinking water.

But what has caused the outbreak of cryptosporidiosis must be found

first.

Dr Walker said nothing definitive had been found yet to confirm the

suspicion that untreated sewage may have penetrated the water supply.

Public health officials say the number of cases of the of the water-

borne stomach bug in Gwynedd and Anglesey has risen again to 123 on

Thursday.

Speaking on BBC Radio Cymru on Thursday, Welsh Water spokesman Gwyn

Thomas said he regretted the inconvenience to its customers in

Gwynedd and Anglesey affected by the outbreak.

When asked whether customers would be compensated, Mr Thomas said the

priority at the moment was " public health " and that only after the

root of the problem was discovered would the company " consider " the

compensation issue.

The list of places where customers have been advised to boil their

drinking water has also been extended overnight to include Llanberis

in Gwynedd plus Ceint and Penmynydd on Anglesey.

Some people have criticised the lack of information, and the delay in

warning all customers to boil their drinking water.

" I am still waiting for something from Welsh Water saying exactly

what we should do, " said Delyth Jones who runs a home for the elderly

in Llanrug near Caernarfon.

" I am very angry that we haven't been told anything. We have to keep

to certain standards here, I don't feel Welsh Water have been keeping

theirs, " she added.

But Dr Meirion Evans, a consultant with the Public Health Service

told BBC Radio Cymru that information had been forwarded to people as

soon as the outbreak control team had gathered the " evidence " that

the bug was becoming a problem.

Despite monitoring, no trace of the bug has been found at the

reservoir

One hundred and ten people have now become ill from the water-borne

stomach bug. Some 70,000 households in Gwynedd and Anglesey will have

to boil water for drinking until at least 9 January.

Symptoms of the cryptosporidium bug are diarrhoea and stomach cramps

and it typically lasts for around a fortnight.

The Cwellyn reservoir at Rhyd-ddu in Gwynedd has been monitored since

the outbreak was first confirmed a week ago but Welsh Water say the

bug has not been identified there.

A Welsh Water spokesman added it was not possible to switch the

supply so people received their water from another reservoir.

He said: " Because this is a difficult geographical area, we cannot

pipe in water from other areas. If we tankered in water, that would

have to be boiled anyway.

Public health experts say the outbreak should " burn itself out " , but

if that has not happened by early January, the advice to boil water

will be extended.

Meanwhile, the National Public Health Service for Wales has responded

to criticism about difficulties getting through to their helpline.

A spokesman said the helpline would now be open an hour longer on

weekdays from 0900 to 1800 GMT, and more people would be answering

calls.

The helpline number is 0845 850 9850.
