Information on the connection processes

Water and Wastewater Connections

Irish Water is responsible for the development and delivery of water and wastewater services to homes and businesses throughout the country as well as facilitating connections to our existing network. The Water Services Act (2007) requires that any person or organisation seeking a new or modified connection to enter into a Connection Agreement with Irish Water.

You can apply for a connection (new or modified) to Irish Water for both domestic & non-domestic premises in the following instances, where you require:

  • A new water or wastewater connection for a new single domestic property.
  • A new water or wastewater connection for a new non-domestic property (i.e. commercial or industrial).
  • A new water or wastewater connection for an existing domestic or non-domestic property.
  • A new water or wastewater connection for new residential/commercial/mixed use multi-property development.
  • A water or wastewater connection to a new property.
  • An upgraded water or wastewater connection to a property (domestic or non-domestic).
  • A water or wastewater connection to existing third party infrastructure where that infrastructure is connected to the public network and is supplied with water by Irish Water or has wastewater discharge treated by Irish Water.

Steps in connection application process

To apply for a new or modified connection, you will need to select your relevant Local Authority.

Standard Details and Codes of Practice for Developers

Standard Details and Codes of Practice for water and wastewater infrastructure

The Standard Details and Codes of Practice outline Irish Water’s requirements and provide technical guidance for developers in the provision of water and/or wastewater infrastructure that is to be installed in developments and that will be connected to the water and/or wastewater networks. 

There are two sets of Standard Details available for developers below – one for water infrastructure and the other for wastewater infrastructure. Each set of Standard Details is accompanied by a Design Risk Assessment (DRA), which outlines the health and safety responsibilities of developers and their designers/contractors in the provision of water and/or wastewater infrastructure.

There are also two Codes of Practice available, one for water infrastructure and the other for wastewater infrastructure. Each Code of Practice is accompanied by a Design Risk Assessment (DRA), which outlines the health and safety responsibilities of developers and their designers/contractors in the provision of water and/or wastewater infrastructure.

The use of Standard Details is mandatory in all Irish Water Connection Agreement Offers issued after 6 June 2016. The Codes of Practice will be mandatory in all Connection Agreements issued from 30th January 2017.

Project Services Works Agreement

Where significant impact on the public water and /or wastewater infrastructure is considered likely as a result of a particular new or modified connection, applicants may be required to enter into a Project Services Works Agreement with Irish Water. A Project Services Works Agreement will require the applicant to pay the financial costs relating to the necessary engineering assessments prior to entering into a formal Connection Agreement.

Connection Charges

Irish Water’s current charges for water and wastewater service connections are the equivalent of the water and wastewater portion of the Development Levies and Connection Fees that were previously included by Local Authorities in their levies/fees structures up until 31 December 2013.

With the approval of the Commission for Energy Regulation (CER), Irish Water has been applying these Interim Connection Charges in the form of (i) Works Fees;  and (ii) Infrastructure Fees; and (iii) Supplemental Fees (where applicable).  These fees are the equivalent of (i) Connection Fees; and (ii) that portion of Development Levies which the Local Authorities (LAs) were formerly entitled to charge for water and/or wastewater infrastructure; and (iii) Supplemental development contribution schemes respectively.

The previous Local Authority Connection Fee is now called a Works Fee and the previous Local Authority Development Levy (for water or wastewater connections) is now called an Infrastructure Fee.

Please contact your Local Authority for information on service connection charges.
