Work progresses on the Lough Egish RWSS to ensure its removal from the RAL
Lough Egish only water supply in Co. Monaghan on EPA's Remedial Action List (RAL)
Works on the Lough Egish Regional Water Supply, the only water supply in Co. Monaghan which is on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL), are progressing and are on track for completion at the end of this year which will see the removal of the supply from the RAL subject to EPA approval.
It remains a priority to have the Lough Egish RWSS removed from the EPA’s action list and Irish Water is progressing its €4.5 million investment programme in the supply for the benefit of its 10,369 users.
Nationally Irish Water has adopted a prioritised programme of works which will require an investment of €2 billion by 2021. Significant improvements are being achieved year on year by this approach, including in Co. Monaghan.
In Monaghan there are no boil water notices in place and the Lough Egish scheme is on the RAL for elevated THMs.
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.
The works to be undertaken by Irish Water in partnership with Monaghan County Council will see the upgrade of the existing Kilkitt WTP and intake at Lough Bawn, together with associated site and ancillary works. Once completed the upgraded treatment plant will have an increased design output of 5.5MLD. Coffey Water Ltd have been awarded the contract and works have an estimated completion date of the end of 2017.
The upgrading of the Kilkitt WTP will ensure that the plant can meet the current water demand whilst also providing capacity to meet future development needs. This project will also ensure that treated water from the scheme complies with the current Drinking Water Quality Regulations and will enable removal of the supply from the RAL, subject to approval of the EPA.
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 works are advancing on the Lough Egish scheme which we are confident of delivering by year end.”
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.
