Water was restored to thousands of homes yesterday afternoon following a burst water mains which caused chaos across Birmingham.

However, motorists were warned to prepare for long delays at rush hour today as work continued to repair the road in Edgbaston where the mains pipe was buried.

It was unclear last night whether Severn Trent engineers were to re-open one of the lanes on Edgbaston Road which was flooded yesterday morning following the burst.

Water supplies to thousands of homes were hit and more than 2,000 primary schoolchildren in Moseley and Hall Green were sent home.

Seven primary schools were forced to turn pupils away after they were left without water.

The burst pipe sent water cascading into Edgbaston Road outside Warwickshire Cricket Club at 6.30am.

It left the normally busy rush hour road under several inches of water, sending drivers on clogged detours.

Switchboard staff at Severn Trent dealt with hundreds of calls from homeowners complaining that their taps had run dry or had been reduced to a trickle.

A spokeswoman for the company said about 15,000 homes, businesses and schools across Moseley and Hall Green were affected by the burst.

They were either completely without water or suffering from very low pressure, but engineers were working on the problem throughout the day.

By the afternoon, engineers at the water company had redirected water from other areas of Birmingham to the worst affected neighbourhood.

A spokeswoman said: "We know that water is coming back to homes and all properties affected will have clean water by the end of the day.

"However, we would warn motorists that they may experience some delays as we do not know when the work will be completed."
