Reservoir stocks remain in a “healthy position” despite the recent spell of warm, dry weather, according to Jersey Water.
The utility said reservoir levels are currently at 96% capacity and there are “no imminent concerns about water shortages”, but warned islanders that the situation could change quickly without significant rainfall.
The island has around 120 days’ worth of water available when reservoirs are full, meaning “responsible water use is essential” to help avoid restrictions later in the year, such as hosepipe bans.
Jersey Water said it was “closely monitoring both water reserves and demand” as temperatures rise.
Over the weekend, islanders used about 21 million litres of water per day – around three million litres more than the average daily use for May.
Demand is expected to climb further during the peak summer months, when daily consumption is forecast to exceed 23 million litres.
Jersey Water said current usage remained in line with normal seasonal trends, but added that demand was beginning to increase.
“We continue to encourage everyone to be mindful of their water use, particularly during warmer periods,” the utility company said.
“Small actions taken by households and businesses can make a significant difference in protecting the island’s water supply over the months ahead.”
