Colin Day, head of water service planning at the company, external, said: “Fresh water is not in infinite supply, and our population is growing with increased urbanisation.

"By using items such as paddling pools and hot tubs, it can pull heavily on our resources – meaning sometimes the water is being used faster than it can be treated into drinking water."
