Capacity registers

Our registers indicate if there's enough water supply and water treatment at Irish Water treatment plants to support property development.

As part of our commitment to support growth and development, we publish annual water supply and wastewater treatment capacity registers.

The indication of available capacity on these registers is based on a standardised review regarding current and future capacity. Capacity is always subject to change.

Investing in water services

In 2014, we created a robust investment planning framework that prioritises investments based on national water services policy and plans for the future.

Our current investment plan was developed following significant consultation with multiple stakeholders and runs from 2020 to 2024. Our next Investment Plan which is due to run from 2025 to 2029 will be developed through a similar stakeholder engagement process.

The indication of Capacity Available has been determined based on a standardised national review of the available information and is subject to change.

Further information on the PCE and connections process can be found in the Connections and Developer Services section of this website.

The viability of a new connection is not agreed until the Connection Agreement contract has been executed.

Supporting growth and development

Investing in water services is key for sustainable planning and development on a national, regional and local level.

Our annual water supply and wastewater treatment capacity registers are part of our commitment to support growth and development in Ireland.

We invest in a range of programmes that support growth in line with statutory plans. The 3 themes that guide the development and delivery of water services are: quality, conservation and future proofing. These are detailed in the government's Water Services Policy Statement.

Our investment plan submissions to the Commission for Regulation of Utilities (CRU) highlight the importance of growth in priority settlements. This supports the objectives as set out in the National Planning Framework and the Regional Spatial and Economic Strategies.
