A boil water notice for customers supplied by the Lough Talt Public Water Supply in Co Sligo and part of Co Mayo has been lifted after being in place for over eight months.

The notice came into effect on 5th February, following the detection of cryptosporidium in the water supply, affecting some 13,000 customers in south and west Sligo as well as the area supplied by the Ogham Group Water Scheme in Co Mayo.

The notice has now been lifted following a meeting yesterday between Irish Water, the HSE and Sligo County Council.

The decision was made to lift the notice with immediate effect as there have been no reported cases of illness in the community and no detections of the cryptosporidium parasite recorded since the end of August. 

However, Irish Water has warned that, until the Lough Talt water treatment plant is upgraded, there is a risk of further detections in the supply and it is possible a boil water notice will be re-imposed if there are more detections.

A planning application lodged by Irish Water in 2015 for a new treatment plant at Lough Talt was refused for reasons of protected habitat at the lake.

A new application was made in May of this year to upgrade the current plant, which Sligo County Council is currently considering.
