Boil Water Notice put in place for the Ballyogarty Water Supply Scheme in Waterford

Irish Water working in partnership with Waterford City and County Council wish to advise that due to a disinfection failure, the drinking water quality entering the Ballyogarty Water Supply Scheme may have been affected and have imposed a Boil Water Notice with immediate effect having consulted with the Health Service Executive. This notice applies to all consumers supplied by the Ballyogarty Water Supply Scheme and all consumers affected by this notice must boil their water before drinking. A map of the Ballyogarty Water Supply Scheme, detailing the areas affected, is available on and is also included in this notice.

Speaking about the Boil Water Notice, Irish Water’s Regional Operations Lead, Ronan Walsh said: “Our crews are on site working to resolve the issues with the mechanical failure and we would be confident that the Boil Water Notice can be lifted quite soon in consultation with the HSE, however we will continue to monitor the supply as public health is our number one priority.”

Water must be boiled (rolling boil for 1 minute and then cooled) for:

  • Drinking
  • Preparing Drinks made with water
  • Preparation of salads and similar foods, which are not cooked prior to eating
  • Brushing of teeth and/or gargling
  • Making of ice. However, ensure you first discard all existing ice cubes in fridges and freezers and filtered water in fridges

IMPORTANT: Boil water by bringing to a vigorous, rolling boil and allow to cool. Cover and store in a refrigerator or cold place. Water from the hot tap of kitchen or bathroom sinks is not safe to drink.

You do not have to boil your water for the following:

  • Personal hygiene, baths and showers
  • Flushing of toilets
  • Watering plants and flowers


  • Domestic water filters will not render water safe to drink
  • Caution should be taken when bathing children to ensure that they do not swallow the bathing water
  • Discard ice cubes in fridges and freezers and filtered water in fridges. Make ice from cooled boiled water
  • If you have pets and are concerned about the impact of providing mains water while this BWN is in place, you should ask your local vet for advice

Only use Prepared Water (boiled and cooled) for the following situations.

  • When preparing foods that will not be cooked (e.g. washing and preparing salads)
  • Preparing Infant Formula. Where a Boil Water Notice is in place, you can prepare infant formula from tap water that has been boiled once (rolling boil for 1 minute) and cooled beforehand. Bottled water can also be used to make up infant formula. All bottled water, with the exception of natural mineral water, is regulated to the same standard as drinking water. It is best not to use bottled water labelled as ‘Natural Mineral Water’ as it can have high levels of sodium (salt) and other minerals, although it rarely does. ‘Natural Mineral Water’ can be used if no other water is available, for as short a time as possible, as it is important to keep babies hydrated. If bottled water is used to make up infant formula it should be boiled once (rolling boil for 1 minute), and cooled in the normal way. Ready-to-use formula that does not need added water can also be used.

Always Take Care:

  • Care should be taken with boiled water to avoid burns and scalds. Accidents can easily happen, especially with children.

How long before the boil water notice can be lifted?

  • We do not know at present, but Irish Water will continue to liaise and consult with the Health Service Executive with a view to lifting the Boil Water Notice as soon as practicable

How will we keep you informed?

You will be kept informed through the following media:
