Frequently Asked Questions

1. What is the issue with the Lough Talt water supply?

The Lough Talt water treatment plant (WTP) currently does not provide adequate treatment and needs to be upgraded. The water supply is included on the EPA’s Remedial Action List (RAL) as the WTP does not provide sufficient protection against cryptosporidium or formation of trihalomethanes (THM). A Boil Water Notice has been issued for the area. Further information on the Boil Water Notice is available here.

2. What areas are served by the Lough Talt Regional Water Supply Scheme?

It supplies Tobercurry and Ballymote and surrounding communities including Annagh, Aclare, Bellaghy, Curry, Lavagh, Ballinacarrow, Carrowneden, Kilmacteige and Coolaney, Cloontia, Doocastle and Quarryfield.

3. What is Irish Water doing to fix the water supply?

In May 2019, Irish Water was granted planning permission to upgrade the WTP. Irish Water is now working with Sligo County Council to upgrade the plant. Once complete, the new plant will provide safe drinking water for the next 10 years, and will allow the Boil Water Notices to be lifted. The long term solution is to provide water from an alternative source. This is being investigated by Irish Water while we complete upgrades to the existing Water Treatment Plant.

4. When will the upgrade works be complete?

We plan to complete the upgrade works by the end of 2020.

5. What does the project involve?

The upgrade project will involve:

  • Addition of new containerised process units
  • Construction of new water tanks
  • Construction of a new entrance onto the R294
  • Landscaping, habitat compensation and ancillary works

6. Can a temporary mobile filtration unit be put in place?

No. The Lough Talt Water Treatment Plant treats 8 megalitres of drinking water per day, and “off the shelf” mobile filtration plants are not available at this scale. The proposed treatment for Lough Talt will use prefabricated containerised treatment units. This will shorten delivery time and ensure that a solution is in place by 2020.

7. What are the benefits of the project?

The upgraded water treatment plant will:

  • Allow Boil Water Notices to be lifted
  • Provide clean, safe drinking water for approximately 13,000 people
  • Remove the Lough Talt Regional Water Supply from the EPA’s Remedial Action List (RAL)
