Irish Water has said there will be no rebate for businesses affected by the loss of their water supply in the northeast.
More than 50,000 homes and businesses in counties Meath and Louth were without water since the pipe burst last Friday.
Managing Director Jerry Grant said that just like over other utility, Irish Water's job is to provide services to the best of its ability, recognising that when assets fail, it is not in a position to compensate people.
"All our revenue is designed to run the service and to invest in the service," he said.
"We have to advise people to look to their insurers for any losses that they've incurred as a result of this unfortunate event."
The repairs of a burst water main have been completed and the water treatment plant at Staleen, Co Meath is now back in production.
Irish Water and Louth County Council said that mains water supply has now been restored to all areas of Drogheda, Clogherhead and Termonfeckin.
Irish Water said water supplies are returning to the rest of the northeast, but said that it could take several days for supply to be fully restored.
It asked householders and businesses to continue to conserve their mains water supply for the next few days until supply has returned to normal.
The utility and Meath County Council also said that the water supply for east and southeast Meath is returning.
Duleek, Stamullen and the coastal areas of Laytown, Bettystown, Mornington, Donacarney and Grangerath currently have close to normal mains water supply. It is anticipated that full mains water supply to the Ashbourne and Ratoath areas will return over the next 24 hours, they said.
Mr Grant said said the pipe has failed in the past and Irish Water still regards it as being at risk.
"We have some fittings to make the next repair faster if that arises, and obviously our intention is to move this up the priority list and try to get it replaced as soon as possible."
Mr Grant said there are many other pipes across the country as vulnerable as this one, that have repairs like this, and that do not fail.
He said, however, there are no guarantees.
Irish Water said earlier: "Rostered mains supply rationing will continue today. As the day progresses we expect to be in a position to supply more areas with a mains supply and gradually remove temporary supply locations."
It added that disturbance in the pipe may result in some people receiving discoloured water or water with sediment, but said it is monitoring water quality and the water is safe to drink.
