Work has begun to build a new water treatment plant on Lough Guitane in Co Kerry.
The plant is being built by Irish Water as part of a €30 million investment in the Kerry Central regional water supply scheme.
More than 62,000 people are dependent on the scheme, which covers nine water supply zones.
All of the zones are currently on the Environmental Protection Agency's Remedial Action List due to lack of adequate water treatment facilities.
It is hoped the required treatment processes are in place by the end of 2017, while the project is due to be completed by mid-2018.
