Irish Water says it is continuing to work on numerous projects in Roscommon to secure high-quality reliable drinking water for over 18,000 people.
In Roscommon, 6,598 residents are on full or partial boil water notices or experience a water restriction. In Ballinlough/Loughglynn the long-term plan is to replace this water source with the Lough Mask supply in Mayo. At the North East Regional treatment plant a full upgrade of the plant is required in the long-term.
Two supplies in Roscommon have elevated THM levels, which have been recorded as above the standard in the Drinking Water Regulations. THMs, or Trihalomethanes are chemicals formed by the reaction of naturally occurring dissolved organic material and chlorine, which is used for disinfection in order to protect against pathogenic bacteria.
In Roscommon, 7,966 people are using water supplies where there are elevated levels of THMs. Irish Water is upgrading the North Roscommon Regional water supply scheme while it is planned to replace the Grangemore scheme with the Boyle/Ardcarne water supply in the long-term.
