Galway RAL reduced from 13 schemes in 2016 down to 2 in 2018

The Inis Meain water supply has been removed from the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) following a programme of works by Irish Water. The supply, which serves a population of 161 people was added to the RAL for elevated levels of THMs in the water. A programme of works has been completed on the island to bring the supply back into compliance.

In 2016 there were 13 Galway water supplies on the RAL. Due to significant investment by Irish Water, this has been reduced to 2 with ongoing works taking place at the remaining plants to ensure their removal from the EPA’s action list by the middle of this year.

This work comes following the removal of 9 boil water notices from water supplies in Co. Galway in the last two years, making Galway currently a boil water notice-free zone.

Removal of remaining schemes

The remaining schemes on the RAL are Ballinasloe Regional Water Supply Scheme, and Williamstown Public Supply both of which are on the RAL for THMs. Works are expected to be completed in Ballinasloe by the middle of this year. Williamstown, which supplies 986 people, will be connected to the Lough Mask Regional Water Supply in early 2018 which will also enable its removal. 

THMs, or Trihalomethanes, are chemicals formed by the reaction of naturally occurring dissolved organic material and chlorine. Chlorine is used for disinfection in order to protect against pathogenic bacteria.

Irish Water has put in place the first national THM plan and a prioritised programme of investment to address all inadequacies in drinking water parameters including THMs. By 2021 the utility plans to reduce the number of schemes on the RAL to zero with an investment of €327 million in upgrading water supplies at risk from THMs.

Ensuring the delivery of clean and wholesome water

Welcoming this latest RAL update Regional Compliance Specialist, Pat O’Sullivan, said “The publication of the latest RAL update is a confirmation of the focus and dedication of Irish Water and Galway County Council in ensuring the delivery of clean and wholesome water in the county. Works are advancing on the remaining schemes which we are confident of delivering in the coming months.”

In November 2015, Irish Water announced an investment of €36 million in water infrastructure and €58 million in wastewater infrastructure across Galway. The RAL is updated quarterly by the EPA for supplies where investment in treatment processes is required. Irish Water has a prioritised programme of investment for all schemes on the RAL.
