Re: Design Submission for Strategic Housing Development at Rialto Student

Accommodation, South Circular Road, Dublin (the “Development”) (the “Design

Submission”) / 5475419949.

Dear Martin,

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

Name: James O’Sullivan

Phone: 02252269

Email: [email protected]

Yours sincerely,

Maria O’Dwyer
