Irish Water said thousands of people "may have experienced some outages"
Water service should be restored to up to 10,000 customers in Meath this evening, after a burst pipe caused outages.
The pipe burst earlier this morning on the Proudstown Road in Navan, which was closed to allow for repair work.
Some residents are reporting water is flowing again after the outages earlier.
Update:— Shane Cassells TD (@ShaneCassells) August 1, 2017
Water now flowing again in Navan Town Centre and should be back to full capacity soon.
In a statement, Irish Water said: "The trunk main that feeds water into Navan town has been successfully repaired. Water is being restored to homes and businesses in north, west and south Navan town and some surrounding areas over the coming hours."
Meath County Council, meanwhile, said the main is being re-charged and supply should return this evening.
Irish Water said between 5,000 to 10,000 customers may have been affected in the areas north, west and south in Navan town and some surrounding areas.
In an earlier statement, the utility said: "There is some water remaining in the network and many customers will have storage in their tanks so may not experience a full outage as yet but will be experiencing reduced pressure."
A new pipe was brought in as part of the repair work.
Tankers were mobilised and were on standby to replenish water storage tanks in Our Lady's Hospital, Navan in case their water storage ran short.
Tankers were also on standby for residential use, but were not deployed as the outage was under 24 hours.

It comes a week after up to 70,000 people in the north east were left without water for almost a week.
