The deputy leader of the council became the latest victim of last week’s burst main when a 12-litre package of water destined for residents was dropped on her foot.
Coun Clare Pritchard was left with a broken left foot as she was trying to help distribute water to Oswaldtwistle residents who had been left without water for nearly two days.
The accident took place at the water distribution centre at Accrington’s Tesco store last Thursday.
Coun Pritchard said she was being passed a six-pack of two litre bottles when it was dropped on her foot.
Coun Pritchard said: "There was no distribution centre in Oswaldtwistle so I asked if I could pick some up and take it to residents.
"I was being handed the water and it crashed on my foot."
Although she nearly passed out from the pain, Coun Pritchard said she did not go to hospital for treatment until later in the day when she found the swelling and bruising had not diminished.
She said: "I went to work thinking I had a bruise on my foot but it didn’t improve so I went to hospital."
She was given crutches at hospital and can expect a recovery period of around six weeks.
Coun Pritchard said it was the first time she had broken anything.
Earlier this week she Tweeted: "Is just loving hopping around into meetings with people laughing at how I did it (NOT!)."
A spokesman for United Utilities said: "We’re really sorry to hear about Coun Pritchard’s foot particularly as she was being very public-spirited and trying to help us distribute water to local people.
"We have contacted her and are investigating what happened."
