Gatwick Water Outage Highlights Single-Supply Risk at Major Airport

A power failure at SES Water's Bough Beech treatment plant on 26 July 2026 cut water to Gatwick Airport and parts of Surrey and Kent. Toilets, bars, and restaurants across both terminals closed. Flights continued. The UK's second-busiest airport has no backup water supply on-site — meaning no redundancy if its single off-site municipal source fails.
