Upgrade will protect local environment and facilitate future growth

Irish Water has submitted a notice of a Compulsory Purchase Order (CPO) to An Bord Pleanála for the purchase of lands in Portmarnock to facilitate upgrades to the wastewater infrastructure at Portmarnock Bridge.

When complete, the Portmarnock Wastewater Project will benefit the local community by increasing wastewater capacity in the area, which will facilitate future growth and development, and protect the environment by reducing overflows to the Sluice River.

The wastewater pumping station at Portmarnock Bridge currently operates at full capacity. This means that during storms, the system is overloaded and overflows to the Sluice River. To reduce the risk of this, Irish Water plan to build a replacement pumping station with over twice the capacity of the existing station that includes storm water storage and new sewer network assets.

Project details

The project involves the construction of a new pumping station at Portmarnock Bridge, which will pump over twice as much wastewater as the existing station, the decommissioning of the existing pumping station, the construction of storm storage to reduce the risk of overflow during storms, and the construction of 1.7km of new rising mains and connection to a larger sewer.

This project is vital in safeguarding the wastewater network in Portmarnock. This upgrade will facilitate future population growth and economic development in the area, as well as protecting the environment by reducing overflows during periods of heavy rainfall.

Irish Water investment plan

This project forms part of Irish Water’s investment plan. Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s Business Plan. Delivery of the business plan will involve a €5.5 billion investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021.
