Gatwick Airport has apologised after a burst main in the Crawley area resulted in a shortage of water on Thursday afternoon and evening.
The burst main led to low water pressure throughout the airport and passengers reported just two toilets were working in one of the terminals.
Passengers also said several restaurants had to shut.
Signs on overhead message boards at the airport warned: “Only limited toilets available due to a local water supply issue. We apologise for any inconvenience.”
A Gatwick spokesperson said: “An issue with the supply of SES Water to Gatwick and the surrounding area this morning has led to lower water pressure than normal across the airport.
“We are working closely with SES Water to ensure this issue is resolved as quickly as possible.
“Bottled water is being made available to passengers and staff across the airport and other contingency measures are being put in place to ensure the welfare of our passengers.
“We apologise for any inconvenience to passengers.”
Utility supplier SES Water said on Friday morning the situation has now been resolved.
A spokesperson from SES said: “We’re pleased to confirm that the burst, in Shipley Bridge, Horley, has been repaired and water supplies have returned to normal.
“We would like to take this opportunity to apologise to anyone affected by the incident yesterday and thank them for their patience and understanding.”
