Mr. Eoin O'Dowd:

Any systems installed and specified, whether to the older British standard or the new European 12845 standard, would have a typical redundancy built in for those essential life-saving characteristics. They do not rely on a dedicated supply. Depending on the height of the building, the pressure to get water to those heights is critical. These buildings could be of any height. Our new technical guidance document for the comprehensive provision refers to a 15 m-plus height, which has a significant requirement of head pressure for pumping. Those supplies must be there. In their absence, you depend on the water in the pipework. These are essential systems that were found prudent as part of the public consultation. That principle was generally supported through the 2020 and the 2024 public consultations for such systems in buildings.
