The first time a member of the public becomes aware that there might be an issue is if there is discoloration, a smell or a taste in the water. The EPA and the HSE outlined their role in the overall process in terms of issuing boil water notices and so on. How does Irish Water escalate reports that come into its call centre? In recent weeks, for example, across Clontarf, some parts of the northside of Dublin, Dún Laoghaire and some parts of north Wicklow there have been reports of an earthy or mouldy taste and smell from the water. Is Irish Water aware of that? If Irish Water gets several phone calls into its call centre, how does that get escalated up and what level of investigation is carried out following the first, second and subsequent calls?
