The wastewater treatment plant was first built in the early 1980’s and needs to be upgraded to bring it in line with modern wastewater treatment processes.

Irish Water has commenced an upgrade to the Enniskerry Wastewater Treatment Plant. The €880,000 investment will increase the treatment efficiency at the plant. The investment includes new inlet works, a new aeration system, new equipment which will reduce noise at the plant and a new odour control system. This investment will benefit people living in neighbouring properties who have previously been impacted by noise and odours due to the age of the equipment at the plant. The upgrade will ensure the plant is compliant with EU Urban Wastewater Directives. The project is expected to be completed in February 2018. 

Investing in Ireland’s wastewater infrastructure is a key priority for Irish Water. Between 2014 and 2015, Irish Water invested €166m in Ireland’s wastewater infrastructure, an increase of 22% from 2011 to 2013. From 2016 – 2021, the remaining period of the Irish Water Business Plan, the utility is ramping up investment to spend an average of €326m per year on wastewater infrastructure. The investment in the Enniskerry Wastewater Treatment Plant is part of this investment programme.

Commenting on the project Ivan Corcoran, Capital Programme Lead with Irish Water said “Investment in the Enniskerry Wastewater Treatment plant is needed to increase the efficiency of the wastewater treatment processes at the plant and reduced noise and odours associated with ageing equipment. This investment will benefit people living near the plant as noise levels and odour issues will be reduced by modernising the plant”.

Irish Water collects wastewater from over 1,000 separate communities connected to the wastewater network and treats around 1,600 million litres of wastewater daily before discharging it back into our rivers, harbours and coastal areas. By 2021, as outlined in the Irish Water Business Plan, we plan to have all discharges to our rivers and seas treated before being released. Our programme of work will include, not only improving capacity to ensure Irish Water can facilitate the growth of the new homes and industry but also protecting our coasts, which has a huge impact on tourism and local businesses.
