Castlemaine Wastewater Treatment Plant Upgrade

Wastewater Project

Works to construct new wastewater infrastructure have been completed which will improve water quality and facilitate future growth of the area.

The wastewater infrastructure in Castlemaine was outdated no longer suitable to meet the needs of the area, with wastewater treated via a septic tank system prior to discharge to the River Maine. In early 2019, Uisce Éireann, working in partnership with Kerry County Council, commenced work on the upgrades to the Castlemaine Sewerage Scheme.

This project is being delivered by Glan Agua Ltd on behalf of Uisce Éireann.

  • The new wastewater treatment plant and network will facilitate future growth in the village and the surrounding area

  • The new plant will treat wastewater to a significantly higher standard, and will ensure that Castlemaine complies with the requirements of both the Urban Waste Water Treatment Regulations and the EPA waste water discharge authorisation
