South East Water says customers in Burgess Hill should be seeing their water supplies return to normal after a large main burst this morning.
A section of pipe burst in Cromwell Road, but also caused flooding in Newport Road, Fairfield Road and Royal George Road.
Repair crews are on site and the company say they're working as quickly as possible to return supplies to normal.
They say water has been re-routed around the network so customers further away from the burst should now have had their supplies restored.
Bottled water is also available at Fairfield recreation ground in Cromwell Road.
A spokesman from South East Water said they're concentrating on helping more vulnerable customers, and those whose homes have been flooded:
“We know this incident has been distressing for our customers whose homes have been flooded and we are doing all we can to help them.
