UPDATE: 22.45pm: South West Water has confirmed a further 14 homes have been left without water following a lightning strike in Newquay earlier tonight.
A spokesman said that the water had to be isolated on Henver Road when lightning damaged a 10 inch water pipe.
Repair works are expected to last anywhere between four and six hours.
But an on-site technician told the Cornish Guardian at 22.30pm that he did not know how long the repairs would take.
EARLIER: A lightning strike has damaged a water main in Newquay leaving 42 homes without running water.
Technicians from South West Water are currently at the scene in Henver Road to try and determine the extent of the damage.
A spokesman from South West Water said it was one of the most bizarre cases they have dealt with recently: “It is very unusual for this to happen, I’ve certainly never heard of it before.
"We have a technician at the scene to try and determine how the lightning damaged the water main.
"We believe the lightning hit a building and somehow ended up damaging the water main.
“There are 42 homes without water at the moment.
