Re: Design Submission for Horgans Quay, Railway Street, Cork (the “Development”)

(the “Design Submission”) / Connection Reference No: CDS19002038

Dear Feargal,

Many thanks for your recent Design Submission.

We have reviewed your proposal for the connection(s) at the Development. Based on the

information provided, which included the documents outlined in Appendix A to this letter, Irish

Water has no objection to your proposals.

This letter does not constitute an offer, in whole or in part, to provide a connection to any Irish

Water infrastructure. Before you can connect to our network you must sign a connection

agreement with Irish Water. This can be applied for by completing the connection application

form at www.water.ie/connections. Irish Water’s current charges for water and wastewater

connections are set out in the Water Charges Plan as approved by the Commission for

Regulation of Utilities (CRU)(https://www.cru.ie/document_group/irish-waters-water-charges-

plan-2018/).

You the Customer (including any designers/contractors or other related parties appointed by you)

is entirely responsible for the design and construction of all water and/or wastewater

infrastructure within the Development which is necessary to facilitate connection(s) from the

boundary of the Development to Irish Water’s network(s) (the “Self-Lay Works”), as reflected in

your Design Submission. Acceptance of the Design Submission by Irish Water does not, in any

way, render Irish Water liable for any elements of the design and/or construction of the Self-Lay

Works.

If you have any further questions, please contact your Irish Water representative:
