No current plans for water use restrictions

There are currently no plans to introduce restriction on water usage, Guernsey Water has said.

Operations manager Jon Holt said stocks were currently "healthy" and "we're in line with our projected storage levels over the summer".

He added: "Obviously throughout the summer we're expecting them to drop and to level out, and then, in October, we would normally start to see recharge, so we would expect the the levels to come back up again."

Guernsey recorded its highest temperature since records began on 25 June, , hitting 36.4C (97.5F)

Holt said the recent spell had impacts on the treated water reserves.

"We have seen very high levels of demand and we had four days each day being over 15 million litres a day," he said.

"We wouldn't normally expect to see that. We would normally expect to see maybe one or two days spread out at 15 million litres a day.

"Overall, over these short periods, it doesn't have a significant impact on the raw water storage but it does have a very immediate impact on treated water storage."

Some forecasters are predicting another spell of hot and dry weather at the start of July, but there is still uncertainty on how hot it could get.

Holt said household could make "small changes" to their habits to help save water in dry weather.

He said: "It's things like not watering the plants in the middle of the heat, taking the first draw from the tap maybe into a jug, the first draw from the shower while you're waiting for it to heat up... things like that just to try to reduce that demand on the system."

He added that turning Les Vardes quarry into a reservoir would help with the network's resilience in future periods of drought.

In 2025, the States agreed to use the former Ronez quarry for fresh water storage.

However, Deputy Andy Sloan said he would put forward a challenge to that decision in a bid to reverse it.
