A sudden failure at SES Water’s Bough Beech treatment works in Kent on Sunday, 26 July 2026, knocked out the mains supply to London-Gatwick, Britain’s second-busiest airport. From mid-morning both the North and South terminals ran dry, forcing bars, restaurants and wash-rooms to close and leaving thousands of holiday-makers and business travellers without running water or working toilets. Airport managers deployed bottled-water stations, portable lavatories and additional cleaning crews, while airlines warned passengers to arrive self-sufficient and expect reduced catering onboard short-haul flights. Although flight schedules continued largely on time, the knock-on effects were felt across the airport ecosystem. Airline lounges limited access, ground-handling crews reported difficulties replenishing potable-water tanks on aircraft, and some carriers imposed weight restrictions to compensate for higher bottled-water loading. Hospitality concessions, already stretched by the post-pandemic labour shortage, saw an estimated £1.5 million in lost takings over the course of the day, according to the Airport Operators Association. The incident has reignited questions about the resilience of the UK’s hub airports to utility failures. Gatwick experienced a smaller water-pressure dip during last summer’s heatwave; Heathrow suffered a similar outage in 2024 that stranded 5,000 passengers overnight. Industry analysts note that, while power-supply redundancy has improved markedly since the 2019 IT shutdown, water infrastructure remains a single point of failure for most UK airports. Under Civil Aviation Authority guidelines, operators must hold contingency plans, but these focus on aircraft turnaround rather than passenger welfare in terminals. For corporate travel managers, Sunday’s disruption is a reminder to build extra dwell time into itineraries during the peak holiday season and to brief travellers on self-care measures—carrying refillable bottles and hand-sanitiser, for example. Insurers also warn that travel policies rarely cover consequential expenses such as missed meetings caused by terminal-side failures that do not lead to flight cancellations. Gatwick says it will review emergency-supply contracts and has invited SES Water to present a remedial timetable this week. The utility has pledged to install additional backup generators and to improve real-time communication channels with major customers. With UK airports preparing for record passenger volumes driven by the post-Brexit boom in outbound leisure travel and the return of long-haul corporate traffic, Sunday’s events underscore the importance of hardening basic services against increasingly frequent climate-related and technical shocks.
