Settlements with Waste Water Discharge Authorisations ‐ Wastewater Treatment Capacity Register

The spare capacity available to treat additional loads at the treatment plants changes regularly based upon the loads received from new and existing customers. This register is only an indication of available capacity based on available information at the date of issue and is subject to change.

This register cannot be taken as confirmation that capacity is available for a particular development. In all instances if you are considering progressing a development you should contact our Connection and Developer Services team who  will provide an up-to-date view, and greater level of detail, in relation to the availability of capacity.

This register provides wastewater treatment capacity information only and does not provide an indication of network capacity. In cases where a new development is planned, we may need to make upgrades to the wastewater network to support the collection of the new load and to mitigate the risk of flooding from occurring to our existing infrastructure. We assess whether the wastewater network can support a new development  during the connections process.

Learn more about the Pre Connection Enquiry and Connection Application process in the Connections section of this site.

At all times an executed Connection Agreement with Uisce Éireann is required to ensure a connection can be made and capacity is available for your development. All new Connections are subject to UÉ’s Connections Charging Policy and at all times the issue of a connection offer is a matter for the discretion of UÉ.

Indication of Available Capacity

This register provides an indication of available wastewater treatment capacity based on loads received in 2022 and available treatment plan capacity now or by completion of a project at construction (where relevant).

• Green = spare capacity available.

• Amber = potential spare capacity, additional analysis of applications may be required on an individual basis considering their specific load requirements. Potential availability of capacity in this case would be dependent on any additional load not resulting in a significant breach of the combined approach as set out in Regulation 43 of the Waste Water Discharge (Authorisation) Regulations 2007, which is a matter for the relevant Planning Authorities to determine

• 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 December 2024.

General notes

• The information in this register has been determined based on a standardised national review of the available information and is subject to change. It is indicative only, non-binding and should not be relied upon.
• 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 (UÉ) to determine the feasibility of connecting any particular site to the UÉ network, feasibility should not be inferred from this register. Note that a positive response to a Pre-Connection enquiry does not guarantee that a connection can be facilitated in future – an executed Connection Agreement with UÉ is required to ensure a connection can be made and capacity is available for your development. All new Connections are subject to UÉ’s Connections Charging Policy and at all times the issue of a connection offer is a matter for the discretion of UÉ. 
• Should there be a material change to the indication of available capacity during the course of the year, this will generally be updated in the web version of the register and the relevant Local Authority will be notified.
