Precautionary Boil Water Notice for impacted customers in North Wicklow and Dun Laoghaire-Rathdown lifted with immediate affect

10 December 2021

Following consultation with the HSE, Irish Water is advising customers that the drinking water can now be consumed as normal

Irish Water working in partnership with Wicklow County Council, Dublin City Council and Dun Laoghaire-Rathdown County Council, would like to inform impacted customers in North Wicklow, and Ballyman and Kill Lane areas of South Dublin, that the Boil Water Notice issued on Monday, 6 December 2021 has been lifted with immediate effect.

Following consultation with the HSE, Irish Water is advising customers that the drinking water can now be consumed as normal.

It was necessary to issue the Boil Water Notice as a precaution following high turbidity at a treated water reservoir at Vartry Water Treatment Plant which impacted the disinfection process. Irish Water’s drinking water and operational experts worked with colleagues in the impacted Local Authorities to carry out the required actions to facilitate lifting the Boil Water Notice as quickly as possible. This included a programme of network flushing to help reduce the amount of time for the plug of inadequately disinfected water to clear the affected area. When this was completed, we began bacteriological testing to verify the water was safe before seeking agreement with the HSE to lift the notice. Satisfactory monitoring results have returned for all areas and the water is safe to drink.

Irish Water’s Regional Operations Manager, John O’Donoghue, commented: “Irish Water, Wicklow County Council, Dublin City Council and Dun Laoghaire-Rathdown County Council County Council would like to thank the customers who were affected by this notice for their patience and cooperation while we worked to ensure the notice could be lifted as quickly as possible. 

“Irish Water recognises the impact and inconvenience caused by the imposition of a Boil Water Notice to homes and businesses. Our priority is the provision of safe, clean drinking water and safeguarding that water supply for the future is a vital focus.

Acknowledging the support of local stakeholders, John added: “We are grateful to members of the public, media, elected representatives and the business community for sharing the information and advice regarding the Boil Water Notice to help ensure we reached as many people as possible.”

Business customers will receive a 40% rebate on the cost of the supply of water to their businesses for the duration of the Boil Water notice and this will be back-dated automatically to 6 December 2021.

Boil Water Notice advice

Water must be boiled for:

  • Drinking
  • Drinks made with water
  • Preparation of salads and similar foods, which are not cooked prior to eating
  • Brushing of teeth
  • Making of ice - discard ice cubes in fridges and freezers and filtered water in fridges. Make ice from cooled boiled water.

What actions should be taken:

  • Use water prepared for drinking when preparing foods that will not be cooked (e.g. washing salads)
  • Water can be used for personal hygiene, bathing and flushing of toilets but not for brushing teeth or gargling
  • Boil water by bringing to a vigorous, rolling boil (e.g. with an automatic kettle) and allow to cool. Cover and store in a refrigerator or cold place. Water from the hot tap is not safe to drink. 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
  • Prepare infant feeds with water that has been brought to the boil once and cooled. Do not use water that has been re-boiled several times. If bottled water is used for the preparation of infant feeds it should be boiled once and cooled. If you are using bottled water for preparing baby food, be aware that some natural mineral water may have high sodium content. The legal limit for sodium in drinking water is 200mg per litre. Check the label on the bottled water to make sure the sodium or `Na' is not greater than 200mg per litre. If it is, then it is advisable to use a different type of bottled water. If no other water is available, then use this water for as short a time as possible. It is important to keep babies hydrated.
  • Great care should be taken with boiled water to avoid burns and scalds as accidents can easily happen, especially with children

Following consultation with the Health Service Executive (HSE), Irish Water, Dublin City Council, Wicklow County Council, and Dun Laoghaire Rathdown County Council confirm that a Boil Water Notice has been issued with immediate effect to protect the health of 17,497 customers supplied by the Vartry Water Treatment Plant. The Environmental Protection Agency (EPA) have been formally notified.

It is important to note that water is still safe to use for hygiene purposes and Irish Water would like to remind customers to follow the HSE COVID-19 advice and ensure frequent handwashing.

The Boil Water Notice has been put in place to protect public health as high turbidity at a treated water reservoir at Vartry Treatment Plant means a small amount of treated water leaving the Reservoir and going directly into part of the Vartry supply was inadequately disinfected for a short period. Irish Water is currently investigating the issue with a view to lifting the precautionary boil notice as soon as possible.

A list of locations included in the Boil Water Notice are provided below

Customers in the following locations in Wicklow are included: Newcastle; Newtownmountkennedy; Kilcoole; Kilpedder; Kilmacanogue Fassaroe/Berryfield Lane; Kilcroney; Delgany;

There are also rural areas between Callowhill and Cronroe which are affected including: Killiskey; Nuns Cross; Coynes Cross; Prospect; Mount John; Timmore Lane; Dunran; Ballyvolan and Kiltimon.

The following areas in Dun Laoghaire Rathdown are also included: Ballyman, Kill Lane and surrounding areas.
