Irish Water has recently completed the installation of an ultraviolet unit at the Westport Wastewater Treatment Plant. The installation will greatly improve the final effluent being discharged from the plant, protecting the sea life in Clew Bay, which is a designated shellfish area.

Westport Wastewater Treatment Plant serves a population of approximately 15,000 people. One of the main benefits of this €230,000 investment is the reduction of the environmental impact of the wastewater discharged from the plant.

As part of this investment in Westport, provision has also been made to allow for future expansion of the plant up to a population of 22,500, supporting both social and economic growth.

Niall O’Donnell from Irish Water’s Minor Programmes section said “Irish Water is working in partnership with Mayo County Council to continually improve wastewater treatment throughout the county. This particular project in Westport will greatly enhance the treatment process at the plant as well as the quality of the final discharge which is released to designated shellfish waters in Clew Bay.”

The works involved the installation of the new automated UV unit, alterations to existing pipework and ducting, commissioning and testing of the new unit as well as installation of a new final effluent sampler.

The project was carried out in conjunction with the upgrade of the Arvagh Wastewater Treatment Plant in Co. Cavan to ensure greater efficiencies and cost saving measures are achieved for Ireland’s national water utility.

This project forms part of Irish Water’s investment plan where over €530 million will be invested in upgrading services in 2016 to improve the country’s water and wastewater infrastructure. The Irish Water Business Plan has earmarked almost €2 billion in improving wastewater quality and capacity up to 2021.
