Some community volunteers have been going door to door to deliver water to vulnerable people, including Conservative county councillor for Colwyn, Cheryl Carlisle.
Ms Carlisle has been sourcing water from outside of Old Colwyn to help those in need and says the emergency response to keep the community safe by Welsh Water has been “woefully inadequate”.
Speaking to Radio Wales Breakfast, she said: “We’ve had some heartbreaking stories, there are currently some nursing homes without water. It’s very distressing for them all.
“I keep thinking of elderly people, if they are not on social media, they will be so bewildered by everything.”
Welsh Water has been asked for a comment, but in a statement on its website, external said it plans to have bottled water stations in place on Friday, but there is a shortage in the bulk supplies of bottled water across the UK.
It added that compensation arrangements will be put in place to those customers affected, while the company uses current supplies to prioritise vulnerable customers.
