Irish Water is pleased to confirm that a major upgrade of the Castlemaine Wastewater Treatment Plant has been completed, bringing big benefits to the local community now and for years to come.

The village, located at the gateway to West Kerry, has long been celebrated in story and song and is a popular destination for visitors to the region. This project will ensure that it can continue to grow and develop, while protecting the waters of the River Maine as well as Castlemaine Harbour and Inch Beach.

The new sewerage scheme comprises a state-of-the-art wastewater treatment plant, pumping station and sewer pipelines to replace the old wastewater infrastructure which was outdated and no longer fit for purpose. It was developed at an overall cost of €6.6m with the Design Build contractor, Glan Agua Ltd., commencing construction works in summer 2019.

This project ends the discharge of poorly treated effluent to the River Maine at Castlemaine, protecting the river which flows into Castlemaine Harbour and ultimately improving the water quality for the entire region. All wastewater discharges will now be fully compliant with national and EU regulations.

This investment will also help secure the future of Castlemaine by providing a platform for future sustainable growth and development.

Anthony Kavanagh, Irish Water Infrastructure Delivery Lead, said : “We are delighted to announce the completion of this essential project here in Castlemaine. Not only will it enhance the environment and protect local waterways, it also ensures that the capacity is in place to support the ongoing growth of this proud and thriving community.

This important investment for Castlemaine underlines Irish Water’s commitment to tackling the sizeable wastewater challenges around the country by upgrading old wastewater facilities and ending the discharge of inadequately treated wastewater.

We would like to thank local residents and businesses for their co-operation and support as we carried out this work over the past 18 months.

Jim Kavanagh, Local Authority Project Manager with Kerry County Council said: “Kerry County Council has worked on developing this project for many years and would like to thank Irish Water for providing the required investment and technical input to deliver this essential project for the people of Castlemaine. With tourism and sustainability playing such a crucial role in all aspects of life in this area, the importance of providing effective treatment of wastewater cannot be overstated, both for those who live and work here and for the many visitors to this most scenic part of Kerry.

Significant capital investment is needed over a sustained period of several decades to address the poor condition of Ireland’s water and wastewater infrastructure. Works have been prioritised to address the most critical issues in line with commitments outlined in the Government’s Water Services Policy Statement and Irish Water’s Strategic Funding Plan. Irish Water has invested €3.8 billion in water and wastewater infrastructure to the end of 2019 and plans to invest a further €5.2 billion under its Capital Investment Programme from 2020 to 2024 in drinking water and wastewater quality and capacity and new infrastructure.
