The Lough Egish scheme was on the RAL for elevated THMs.

The Lough Egish Regional Water Supply Scheme has been removed from the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) following a €4.5 million investment programme by Irish Water. This means that Co Monaghan is a RAL free zone. Almost 8,500 customers supplied by this scheme are now enjoying a compliant, clean and secure water supply. 

Upgrade Works

The works undertaken by Irish Water in partnership with Monaghan County Council involved the upgrade of the existing Kilkitt WTP and intake at Lough Bawn, together with associated site and ancillary works. Coffey Water Ltd carried out this contract on behalf of Irish Water.

The upgrading of the Kilkitt WTP means the plant can meet the current water demand whilst also providing capacity to meet future development needs. This project also ensures that treated water from the scheme complies with the current Drinking Water Quality Regulations.

National Plan

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.

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.

Speaking about the RAL and the ongoing work in Monaghan, Irish Water’s 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 Monaghan County Council in ensuring the delivery of clean and wholesome water in the county. It is encouraging to see that there are no Co Monaghan water supplies on the RAL which is testament to the level of investment by Irish Water in this county.”

The Remedial Action List

The RAL is updated quarterly by the EPA for those water supplies where investment in treatment processes is required. Irish Water has a prioritised programme of investment for all schemes on the RAL and the current updated RAL which showed a reduction from 108 to 98 schemes is a reflection of this progress.
