Islanders and visitors have been reminded of the need to save water ahead of the new season.
The Council said that efforts must be made to avoid a repeat of last summer’s shortages.
A notice titled ‘Help us avoid a water shortage’ asks residents, businesses and visitors to takes what steps they can to reduce the amount of water they use.
Lead Member for Place Cllr Steve Sims called the notice “a bit of a pre-emptive strike”.
He said: “Everyone made fantastic efforts last summer when it looked like we could have very real problems. We’re not at that stage this year, but we could be.
“We didn't have a particularly wet winter but if we all use a bit of common sense and use less water when we can and don't waste water then we should be absolutely fine.
“This summer may be nowhere near as hot as last year but we might be lucky again and every litre saved now is a litre we have in reserve in July."
