'Extensive' damage has been caused to an Ipswich treatment works in the wake of Storm Babet which left thousands of homes without water.
Anglia Water has restored water to all of the affected homes and says once everything is back to normal it will "start the ball rolling on any compensation due".
Storm Babet caused chaos in Suffolk over the weekend, with Ipswich also suffering from the heavy downpour on Friday.
Anglian Water's treatment works at Whitton was unable to cope as a result, meaning the company were unable to supply water to some areas of the town.
The company said this affected around 3,000 homes.
Some residents in the area were without water for 24 hours from 6pm on Friday evening through to Saturday.
Anglian Water released a statement on Monday stating they were "so pleased" that a "normal water supply for everyone who was affected on Friday and Saturday has been restored.
It continued: "It was already a horrible weekend with the effects of Storm Babet, but we know that having your water supply disrupted or even disappear completely was a worrying time for you.
"We're so sorry for putting you through it.
"Our teams on the ground want to say thank you for your patience and understanding.
"We've had people out working tirelessly all weekend to fill up and bring tankers to your community, find and open valves to get water flowing from different parts of the network, and support our most at risk customers.
"We know none of it was as quick as you would've liked, but we can hand on heart say that there's been no let up in effort from our guys and girls on the ground."
They have said that there is still work to do at their treatment works in Whitton, with the flood damage being so 'extensive'.
The statement continued: "Once everything is back to normal, our dedicated interruptions team will be looking at who was completely off water and for how long, so we can start the ball rolling on any compensation due.
"This will be done automatically so there's no need to get in touch."
