This water should not be used for

  • Drinking
  • Drinks made with water
  • Food preparation, washing or cooking of food,
  • Brushing of teeth
  • Making of ice
  • Children under 12 months old should not drink this water
  • In particular, children under 12 months old should not drink this water. This water should not be used for making up infant formula for bottled fed infants. An alternative source of water should be used. 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.
  • Domestic water filters will not render water safe to drink
  • Caution should be taken when bathing infants to ensure that they do not swallow the bathing water
  • Discard ice cubes in fridges and freezers and filtered water in fridges

What can you use water for?

  • The water can be used for personal hygiene, bathing, flushing toilets, laundry and washing of utensils
  • Uisce Éireann and Clare County Council will continue to liaise with the Health Service Executive with a view to lifting this drinking water restriction as soon as practicable.

Business customers

Business customers will receive a 40 per cent rebate on the cost of the supply of water to their businesses for the duration of the Do Not Consume Notice.


Updates will be available from our Water Supply Updates section, on Twitter @IWCare and via our customer care helpline, open 24/7 on 1800 278 278.


Uisce Éireann is in receipt of water quality sampling results which are showing elevated levels of manganese in the Shannon/Sixmilebridge regional water supply scheme.

Affected areas

This scheme serves the areas shown on the attached map and includes Shannon, Newmarket-on-Fergus, Sixmilebridge, Kilmurry, Cratloe, Quin, Kilkishen and surrounding areas including group water schemes

This may be observed as a cloudy appearance to water coming from the cold kitchen tap. 

Uisce Éireann is carrying out further sampling of the water supply. Uisce Éireann are in consultation with the HSE in relation to this issue. Please note that high manganese levels in drinking water can be a risk to health. Some groups in the population are more vulnerable such as babies in the womb, infants and young children - see the attached "Frequently asked questions Information Note from HSE".

Uisce Éireann will notify local customers of any additional advice in relation to their local water supply. Further updates will be issued over the weekend.

Details will also be provided via our customer contact centre at 1800 278 278.


What is Manganese?

Manganese occurs naturally in the environment and is also found in many foods in the diet (e.g. vegetables, tea). It also occurs naturally in some water sources and is removed during water treatment process. Manganese is an essential element and is required by mammals and birds for normal growth. Most divalent compounds are soluble in water, as is heptavalent permanganate. The most common tetravalent compound, Manganese Dioxide, is insoluble. Manganese is principally used in the manufacture of iron, steel and alloys. In the Drinking Water Regulations it is defined as an Indicator parameter.

What is an exceedance for Manganese?

The limit designated in the EU drinking water directive for Manganese is 50µg/l. Therefore any result above this level is an exceedance for manganese.

How can an exceedance for Manganese occur?

Manganese exceedances in a drinking water supply may point to pollution of the source water although some exceedances arise from naturally-occurring high levels at source.

How is an exceedance for Manganese dealt with? 

All Exceedances of drinking water parameters are reported to the EPA and also the HSE where necessary. Drinking water parameter exceedances are fully investigated to determine the cause and appropriate corrective actions are implemented.
