Keith Leech, chair of trustees for the traditional Jack in the Green event, said: “On a Bank Holiday weekend that’s absolutely not what the town needs.
“All the pubs and restaurants, and hotels, were thinking of having to close but fortunately on this side of town they’ve managed to maintain a supply.
“Hastings being Hastings, we’re going to do it regardless of what’s going on.”
Four water stations set up at Tesco and Asda in St Leonards as well as a site in Sea Road and at Hastings Academy will continue to operate until 21:00 BST on Monday.
The company apologised “for the disruption this outage has caused, especially over the bank holiday weekend”.
