Government Approves New Waste Water Treatment Plant for Arklow

The Minister for Housing, Local Government and Heritage, Darragh O’Brien TD, has received Cabinet approval for the construction of a new Waste Water Treatment Plant in Arklow, Co. Wicklow.

Construction on the project, which has an estimated overall cost of €139.3 million, is due to begin in Q1 2022 and be completed by September 2025.

Commenting Minister O’Brien said, “the construction of this waste water treatment plant is pivotal for the future growth and development of Arklow town, and for the successful delivery of housing.”

“It is also a hugely important step to rectifying the unacceptable situation whereby untreated waste water is released directly to the Avoca River. Arklow town has no waste water treatment infrastructure, and is cited in the 2019 Court of Justice of the European Union’s judgment against the State for failing to meet the Urban Waste Water Treatment Directive.”

“The people of Arklow have been waiting for decades for this project which will be designed and constructed to cater for a growing population, will facilitate economic development and importantly, safeguard the environment,” he concluded.

The project will include the development of a new, state of the art, wastewater treatment plant at the Old Wallboard Factory site located at Ferrybank in Arklow, two interceptor sewer pipelines (along North and South Quay) to bring untreated wastewater to the proposed plant and a marine sea outfall pipe to safely discharge the treated wastewater effluent to the Irish Sea.

The scope of works for Arklow Wastewater Treatment Plant is as follows:

• New wastewater treatment plant providing secondary treatment with a capacity of 24,000 Population Equivalent (PE) upgradable to 36,000 PE.

• Storm water tank with a capacity of 3,150 cubic metres (m3).

• 930 metre long sea outfall for treated effluent.

• Short sea outfall for storm water overflows.

• Upgrade rock armour on shoreline adjacent to the wastewater treatment plant.

• Extensive collection network upgrades and provision of storm water storm water tanks including for example 120 metre tunnel under the Avoca River and associated storm water overflow.
