Capacity Registers

Introduction

Since establishment in 2014, Irish Water has developed and implemented a robust investment planning framework based on international best practice.  This framework prioritises investment needs based on national water services policy and effective future planning.  Irish Water’s current Capital Investment Plan covers the period 2020 to 2024 and was developed following wide-ranging consultation with stakeholders.

Investment in water services is a key factor in enabling proper planning and sustainable development in the national, regional and local context. We are investing in a range of programmes that will support this growth as identified in the appropriate national, regional and local level statutory plans as part of a balanced portfolio of investment across the three themes of the Water Services Policy Statement (Quality, Conservation and Future Proofing). 

Irish Water’s submissions to the CRU on investment plans calls out the importance of providing for growth in priority settlements as identified in the National Planning Framework and the Regional Spatial and Economic Strategies.

As part of Irish Water’s commitment to supporting growth and development, we are publishing water supply and wastewater treatment registers to provide an indication of available capacity at our treatment plants.

Water Supply Capacity Register

Irish Water has prepared a water supply capacity register to assist planners, developers and other persons identify where there could be sufficient water supply at water treatment plants to provide for potential development.

The indication of available capacity must not be taken as confirmation that a connection will be granted.  Developers should liaise with Irish Water through the submission of a Pre-Connection Enquiry (PCE) in order to determine the feasibility of connection to the Irish Water network. Feasibility cannot be inferred from this register.

The register is provided for Cities, Regional Growth Centres and Key Towns in each of the regions – Eastern and Midlands, Southern and North Western.

The indication of available capacity to meet targeted population growth to 2031 is calculated on the basis of estimates of future populations in settlements which are informed by national, regional and local planning policy. It is only an indication of the ability of a water resource zone to produce water and will be updated annually.

Network capacity is not considered in this register. While there may be capacity available at the treatment plant, in some instances, works may be required to service a particular development. For example, it may be necessary to upsize a pipe to deliver the required amount of water to a site without causing problems for other customers on the network. The ability of the network to cater for a proposed development would be assessed through the new connections process.

For settlements where there are supply capacity constraints, developers should engage with Irish Water through the Connections and Developer Services team. Applications will be considered on a first come, first served basis. Information on planned projects can be viewed at the Projects section of this website.

The indication of Capacity Available has been determined based on a standardised national review of the available information regarding current and future treatment capacity and is subject to change. We will continue to make capacity improvements through the use of the 3 pillars as defined in the National Water Resources Plan Framework. These are:

  • Lose Less- leakage reduction and network efficiency
  • Use Less- water conservation measures
  • Supply smarter – sustainable supplies.

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.

Wastewater Treatment Capacity Register

Irish Water has prepared a wastewater treatment capacity register to assist planners, developers and other persons identify where there could be sufficient wastewater treatment to provide for potential development.

The indication of available capacity must not be taken as confirmation that a connection will be granted.  Developers should liaise with Irish Water through the submission of a Pre-Connection Enquiry (PCE) in order to determine the feasibility of connection to the Irish Water network. Feasibility cannot be inferred from this register.

The register gives a county by county snapshot of wastewater treatment capacity for all settlements with Irish Water treatment plants and will be updated annually. The estimates are made in relation to the load at the treatment plant in the year preceding the publication of the capacity register.

The 2019 register can be accessed in the link below. An updated register to reflect the 2020 loads will be made available in December 2021.

The register does not consider network capacity. In some instances, upgrades to the network may be required to convey the additional load from a new development to the treatment plant without causing flooding or other issues on the network. The ability of the network to cater for a proposed development would be assessed through the new connections process.

Available capacity at any plant varies daily, so the registers are only an indication of capacity. For settlements where there are treatment capacity constraints, developers should engage with Irish Water through the Connections and Developer Services team. Applications will be considered on a first come, first served basis. Information on planned projects can be found in the Our Projects section of the Irish Water website.

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.
