Arklow Wastewater Treatment Plant

Arklow has been identified by the Environmental Protection Agency (EPA), as an area where wastewater is discharged into the Avoca River without any treatment. This practice of discharging untreated wastewater to the river is no longer acceptable and Irish Water intends to fix this problem in partnership with Wicklow County Council.

The provision of a new wastewater treatment plant in Arklow will bring benefits to the town and surrounding areas in terms of health, environmental protection and improved water quality for all.

Project Objectives

Arklow Wastewater Treatment Plant must be delivered in a way that not only meets the required legislative standards but that also ensures that all works are undertaken in a safe and environmentally responsible manner, in cooperation with the local community.

The objectives of the Arklow Wastewater Treatment Plant project are as follows:

  • To stop the current practice of discharging untreated wastewater to the Avoca River
  • To provide a wastewater treatment facility that will comply with all relevant legislative requirements and will service the population of Arklow into the future
  • To improve water quality in the Avoca River

What is involved?

Irish Water intends to develop the Arklow Wastewater Treatment Plant Project which includes:

  • A new, state of the art, wastewater treatment plant that has been designed to provide an ultimate treatment capacity for a PE (population equivalent) of up to 36,000 at the Old Wallboard Factory, North Quay, Ferrybank
  • Sewer pipelines (along the North and South Quays) to bring the untreated wastewater to the WwTP
  • A marine outfall pipe to safely discharge the treated wastewater to the Irish Sea

What is happening now?

Irish Water is delighted to announce that contracts have been signed with engineering contractors, Ward and Burke Water Limited, to begin works on a new, state of the art, wastewater treatment plant in Arklow.

Ward & Burke are currently working on site to assess the next phase of works, which will commence on 27 September 2021. This will include site investigation and clearance to allow the construction works associated with the wastewater treatment plant to follow.

In the coming months, Ward & Burke will fully mobilise on the site of the Old Wallboard factory, installing site offices and welfare facilities. Demolition works of existing buildings will commence on the site, followed by the sinking of a caisson for a large inlet pump station structure.

On the North & South Quays, traffic management measures will be agreed with Wicklow County Council and implemented, allowing Ward & Burke to undertake site investigation works, service diversions and the sinking of 2 no. tunnel shafts.

Proposed Working Area Locations 27th September – 23rd December 2021

Stakeholder Engagement

Irish Water will be engaging with impacted stakeholders in the coming weeks and months with further information on the planned works. We will endeavour to keep you updated as the project progresses.
