More than 3,000 homes were left with no water or low pressure after two mains burst.
Damaged pipework in Miles Grey Road and Upper Mayne in Laindon caused the houses to be left with below-normal levels of water pressure on Sunday afternoon.
Essex and Suffolk Water, who repaired the damage and restored supply within two hours, said hot and dry weather can cause pipes to crack.
The road and footpaths are being reinstated by the water company, which they expect to be completed by the end of the week.
The firm has called extra teams into action to respond to similar incidents across the region so they can act as quickly as possible.
An Essex and Suffolk Water spokesperson said: "Yesterday, our teams responded to two bursts on water mains in Miles Grey Road and Upper Mayne in Laindon, Essex.
"The teams arrived on site quickly, and isolated both of the mains - during which time customers may have experienced lower water pressure than normal.
"Repairs on both bursts were completed and all customer supplies were fully restored within two hours. There is no traffic management in place, but we are in the process of reinstating the road and footways, and expect this to be completed by the end of the week.
"Following prolonged periods of hot, dry weather, the ground can dry out and shift, placing additional pressure on pipework. This can loosen joints and fittings and, in some cases, cause pipes to crack.
“We’ve mobilised additional teams across our network to respond to incidents and repair leaks as quickly as possible.
“We’d like to thank customers for their understanding and apologise for the inconvenience caused.”
