Street floods after water main bursts

Residents remain without tap water after a burst water main flooded a street in Sydney's northwest.

Driveways and front yards were inundated after the burst main sent water pouring into Hull Road in West Pennant Hills.

Fire crews attended the scene as some houses sustained water damage.

"Our neighbours have submerged downstairs but fortunately my driveway has taken all the run-off," one resident said.

Sydney Water has said the break should be repaired by 10pm tonight.

They have distributed bottled water to affected residents.
