A woman was stunned when she opened the tap in her kitchen and the water was BLUE. Anne Gray, 44, had been without water for five days after a planned citywide disruption.
But when the water flow was restored to her home, it came out blue. Video filmed on 17 December 2024 shows water running into the kitchen sink, clearly revealing its bright blue colour against a white in plate.
Anne, a business coach from Johannesburg, South Africa, said: “ When I turned on the tap and couldn’t believe it. The water was bright blue!
“My first thought was ‘What on earth is in this water? The same thing happened in all the bathrooms and I was worried it might not be safe to drink.”
The outage, which began on 13 December, was announced in advance as part of a major maintenance project to improve water capacity in the city.
According to Anne, the blue colour was caused by oxidization in copper pipes during the outage, which created a bluish compound that flushed out after about 10 minutes.
Anne said: “It’s not something I’ve ever seen before. We’ve had sediment or cloudy water after outages but blue water? Never.”
Despite the water returning to normal, Anne remained cautious and continued using her stored drinking water for another day.
