Thousands of homes in Dublin are still experiencing water shortages, with local authorities predicting the water crisis will continue into next week.
Dublin's four local authorities are struggling to cope with the demand for repairs to leaks and burst mains in the city, and water supply is being restricted.
Dublin City Council says it will take between five and six months to fix all the broken water mains across the city, and it dubbed the current water shortage as still critical.
A spokesperson told the Herald that problems will persist into next week, and it will take the city's reservoir between 2-3 months to replenish itself fully.
Water mains are currently being repaired by council workers at a rate of 20 per day.
Dublin Lord Mayor Eimear Costello urged householders to be more conservative when using water.
"Due to the critical shortage of treated water I would urge each and every one of us to be miserly in our use of water," Ms Costello said.
"Please do not use power hoses to wash windows, cars or clean the path. Please do not run the tap unnecessarily. "
Meanwhile on the south side, engineers, water inspectors, technicians, maintenance crews and customer service staff have all been working "round the clock," according to a spokesperson in Dun Laoghaire Rathdown County Council.
The Killiney/Ballinclea area had "specific" problems yesterday, and the council restricted the county's water supply again last night between 7pm and 8am.
A fleet of up to 11 water tankers has been dealing with emergencies during the crisis, one of these was a 30,000 litre capacity tanker donated by Guinness (Diageo).
"We continue to respond to any specific requests from hospitals and nursing homes as they arise," said the spokesperson.
But from tomorrow, only one static tanker will be needed to serve the needs of householders in the county, she added.
Fingal County Council has warned that it may take a number of weeks until supply of water is no longer disrupted, and it is also reducing pressure at night to allow reservoirs to fill up.
"We will continue to do this until water storage levels return to such a level that supply is no longer disrupted," a spokesperson said.
Fewer than 50 houses in the rural Garristown area are still without a water supply due to a burst water main, and residents at areas of high ground such as Howth, and occasionally persons at the end of the network are experiencing low pressure.
A spokesperson added: "Due to a burst watermain this morning on the Ballyboghill to Naul Road, some rural dwellings in the Naul area experienced loss of water supply earlier yesterday. Water supply was restored yesterday afternoon."
A spokesperson for South Dublin County Council said water supply has been restored to all areas, but it is restricting water supplies in all areas within the county from 7pm to 7am everyday.
"We'll be doing this until at least Monday the 25th, and we're monitoring the situation on an ongoing basis."
