Standard Details and Codes of Practice for Developers
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 is mandatory in all Connection Agreements issued after 30th April 2017.
The design of gravity sewers in new developments is to be carried out in accordance with Appendix C of the Code of Practice for Wastewater Infrastructure subject to the additional requirements and clarifications outlined below in the Frequently Asked Questions (FAQ) for the Codes of Practice (Version 3 - January 2019). This takes account of revised design criteria which are to be used now and which will be incorporated in the next issue of the Codes of Practice due later in 2019.

Standard Details Exemptions
Developers may apply for an exemption on the use of the Standard Details for a minimum period in situations where significant design rework would be required or where infrastructure installation is already underway.
Developers are required to apply for exemption approval using the Standard Details exemption application form below.
Connection to Irish Water networks through third party infrastructure
Self-Lay Connection Agreements
Developers should note, where a request for connection to Irish Water’s Network(s) is received which involves a connection through third party infrastructure not yet taken in charge by a local authority, the Developer will be required to:
- Identify the elements of the third party infrastructure required to convey the water and/or wastewater from the development to the Irish Water Network(s) (the “Arterial Pipes”)
- Satisfy Irish Water that the Arterial Pipes have adequate capacity and have been sufficiently constructed to convey the proposed water and/or wastewater loads
- Procure the transfer of the Arterial Pipes to Irish Water
The identification and transfer of the Arterial Pipes will be required as a pre-condition to the commencement of the Self-Lay Works by the Developer.
Confirmation of Feasibility
Confirmation of Feasibility (COF) issued to Developers in response to Pre-Connection Enquiries (PCEs) will outline these requirements where connections are requested through third party infrastructure. For developments which have already received a COF and which fall into this category of development, developers should note that the Connection Agreement(s) will reflect these requirements.
Please note that responsibility for securing consent to connect to third party infrastructure and for arranging the transfer of the Arterial Pipes rests with the Developer.
Strategic Housing Developments - Frequently Asked Questions
The Planning and Development (Strategic Housing Development) Regulations 2017 which comes under the provisions of the Planning and Development (Housing) and Residential Tenancies Act 2016 allows for certain types of planning applications to be made direct to An Bord Pleanála. These are referred to as Strategic Housing Development (SHD) and the FAQ below relates to these development proposals.
Quality Assurance Manuals
Connections and Developer Services has prepared two Manuals which set out the Quality Assurance Requirements for Design and for Field Inspections, which summarize the quality assurance requirements of the Codes of Practice. The Quality Assurance Design Requirements Manual outlines to developers the requirements that apply to the preparation and submissions of design proposals for water and wastewater infrastructure to Irish Water for vetting. The Quality Assurance Field Inspection Requirements outline to developers the interactions, tests, inspections, etc. that are required when the water and wastewater infrastructure is being constructed. These Manuals can be accessed via the following links:
Project Works Services 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 Works Services Agreement with Irish Water. A Project Works Services Agreement will require the applicant to pay the financial costs relating to the necessary engineering assessments prior to entering into a formal Connection Agreement.
