Indication of Available Capacity

This register provides an indication of available wastewater treatment capacity based on loads received in 2021 and available treatment plan capacity now or by completion of a project by 2024 (where relevant).

• Green = spare capacity available.

• Amber = potential spare capacity to be considered on case by case basis.

• Red = no spare capacity available at present.

WWTP Project Planned/ Underway

Project planned or underway to increase capacity and/ or improve treatment performance, based on available information in June 2022.

General notes

  • The indication of available treatment capacity has been determined based on a standardised national review of the available information.
  • The information in this register is subject to change.
  • This register provides commentary on the available capacity at the WWTP, it does not consider the capacity of the sewer network.
  • A Pre‐Connection Enquiry should be submitted to Uisce Éireann to determine the feasibility of connecting any particular site to the Uisce Éireann network, feasibility should not be inferred from this register.
