The water supply to the island of Colonsay in the Inner Hebrides is automatically switched off when met with high demand to avoid wastage.
The supply has to be manually switched back on again in order for water to reach homes.
According to reports, the water supply had to be manually reset five times over the weekend as more and more residents took part in the ice bucket challenge.
David Johnston from the island’s Colonsay Brewery told The Sun: “The challenge spread round the island like wildfire. It hit a peak on Sunday evening. The water system must have thought there was a burst main.”
Scottish Water released a statement saying that there was no shortage of water, but that the increase in demand has affected the island’s water system.

Many critics of the charity craze have pointed out that the challenge encourages people to waste water.
Actor Matt Damon went as far as to use toilet water for his nomination in order to avoid wasting water.
