Police blocked off a Dersingham junction after gallons of water flooded into homes.
Residents heard a “boom” as the water main burst on Station Road at around 6.45am yesterday.
Three fire crews pumped water from the road onto the adjacent recreation ground but unfortunately three homes in Station Road were flooded.
Sandra Green, who runs the Tropics Fish and Chip shop, called the emergency services after being woken by the noise.
She said: “It made a ‘boom’ noise and I initially thought something had collided on the junction.
“The amount of water on Station Road looked like a river. My son is 6ft tall and the water was well over his knees as he tried to warn other residents.”
Mrs Green’s shop escaped the flooding.
Her son Keith Green looked out of the window and saw the road was under water and dialled 999.
Speaking while the incident was ongoing, Mr Green added: “We have no power, no water, nothing. We are going to have to shut down our business. We will only be able to open again after everything has been said to be safe.”
Firefighters from Sandringham and Hunstanton were called out to pump out the water.
Anglian Water engineers were on the scene by 8am and able to stem the flow of the water.
But the road had to be closed while the repairs were undertaken.
Emma Staples from Anglian Water said: “We’re very sorry that a burst on a six-inch water main has caused flooding to three properties in Station Road.
“ Our insurance and clean-up team has visited each of them to arrange to put everything right as soon as possible.
“Our engineers stopped the leak and started the repair and worked hard to complete this as soon as possible. Unfortunately, we had to close Station Road to finish the road works, and we are sorry for any traffic disruption.
“We know how distressing flooding can be, and it is our priority is to put things back to normal for all customers affected.”
