Several schools are closed today due to a lack of water or very low pressure in the Tewkesbury area.
Severn Trent Water have apologised, saying their teams are working to "get things back to normal".
We’re using drones to find where the burst is and we now even have a helicopter out.
We know how difficult it is to have no water, and we’re really sorry for the inconvenience this will be causing.
Bottled water is being supplied to customers for collection from the Morrisons on Barton Lane, Tewkesbury GL20 8AB until 10pm.
The water supplier say they are also taking water into the area using their "fleet of tankers" and will work to deliver bottled water to vulnerable customers.
