LONDON, UK- London Gatwick Airport (LGW) temporarily lost its water supply on one of the busiest weekends of the summer holiday season, disrupting operations across both terminals. The outage affected passengers, airport facilities, and food outlets as authorities worked to restore service.
The disruption impacted travelers using London Gatwick Airport (LGW), including passengers flying with airlines such as British Airways (BA), easyJet (U2), TUI Airways (BY), and Vueling (VY). Airport staff distributed bottled water while essential facilities remained unavailable.
London Gatwick Water Outage
London Gatwick Airport (LGW), the United Kingdom’s second busiest airport, confirmed at around 11:00 a.m. on Sunday that a failure in the local water supply had affected both its North and South terminals.
Without running water, passengers were unable to flush toilets or wash their hands, creating long queues and sanitation concerns throughout the airport. Restaurants, cafés, and other food concessions were forced to suspend operations because they could not safely prepare or serve food.
Airport staff responded by distributing bottled water to travelers coping with warm summer temperatures across southeast England. Despite the disruption, flight operations continued while airport teams focused on supporting passengers.
According to PYOK, the incident occurred during one of the busiest travel periods of the year, significantly increasing the impact on passengers passing through the airport.
Power Outage at Water Treatment Plant
The disruption was traced to a wider infrastructure issue affecting the Horley area, where Gatwick Airport is located.
Local utility provider SES Water explained that a power outage shut down the Bough Beech Water Treatment Works early Sunday morning. Although electricity was later restored, the company encountered several technical complications that delayed the return of normal water service.
The problem was first reported around 6:00 a.m. on July 26. Engineers worked for nearly eight hours before the treatment facility resumed operation.
Even after the plant restarted, SES Water warned that it would take additional time for water pressure and supply to return fully across the affected network.
In a public statement, SES Water apologized for the disruption and thanked customers and Gatwick Airport for their patience while restoration work continued.
Busy Airport Faces Pressure During Peak Holiday Season
The outage came during one of the busiest periods of the summer travel season.
London Gatwick Airport (LGW) handled more than 42 million passengers during the previous year and currently operates close to its maximum permitted capacity. With thousands of passengers moving through the airport daily, even a short disruption to essential utilities can have widespread operational consequences.
Although the lack of water affected passenger amenities and commercial operations, there were no reports that the outage resulted in the closure of the airport or suspension of flight movements.
Gatwick Continues Plans for Future Capacity Growth
While managing the immediate disruption, Gatwick continues advancing long-term infrastructure improvements designed to increase capacity.
The airport was originally constructed with two parallel runways. However, international aviation safety standards currently allow only one runway to be used for regular arrivals and departures because of the limited separation between them.
Today, the southern runway, designated 08R/26L, handles normal flight operations, while the northern runway, 08L/26R, primarily serves as a taxiway.
Under Gatwick’s expansion proposal, the centerline of the northern runway will be moved approximately 12 meters north to meet international safety separation requirements. Once completed and approved, the modified runway will support routine flight operations and significantly increase the airport’s overall capacity without constructing an entirely new runway.
Infrastructure Reliability Remains Essential
The incident highlighted how failures in essential public infrastructure can quickly affect airport operations beyond aircraft movements. Access to running water is critical for sanitation, food preparation, passenger comfort, and day-to-day terminal operations.
As passenger numbers continue to grow and Gatwick pursues future expansion, maintaining resilient utility infrastructure will remain an important part of supporting reliable airport operations during peak travel periods.
