16,000 people outside Dublin are without water supply following the recent freezing temperatures.

This includes 12,000 customers in Co Tipperary whose supply was contaminated by kerosene.

A further 37,000 people in the Greater Dublin area have a restricted supply.

Irish Water has said it is making significant progress to repair burst water mains.

It said three major bursts in Dublin have been repaired, but restrictions on supply will be imposed in the Greater Dublin area again from 8pm tonight until 6am tomorrow.

There are still 12,000 people on boil water notices, the majority of whom are in the Enniscorthy region of Co Wexford.

Irish Water has said there was a drop in demand for water overnight due to the measures it has taken.

It said water levels in the reservoirs feeding Dublin have risen for the first time since the crisis began.

But it said there continues to be some problems getting water supply flowing to the outreaches of the Dublin water network when the flow is turned back on after the overnight restrictions.

There are also some problems getting water to the higher levels in tall buildings, such as apartment blocks, and locations on higher ground.

It has also become aware of very significant leakage issues in the pipe network supplying the Rathmines, Rathgar and Miltown areas of Dublin. Ballyboden and Mount Venus Road were also without water.

Irish Water is asking people to conserve water by taking some simple actions:

  • Take shorter showers - four minutes or less
  • Turn off your taps when brushing your teeth
  • Keep a jug of water in the fridge rather than running a tap for cold water to drink
  • Reduce the use of dishwashers and washing machines, only using when full

Unlike Monday night, the public utility did not restrict the water supply in these areas last night.

Despite this, there were still significant difficulties with a lack of water in the area.

Irish Water has put those problems down to the existence of a significant problem with leaks in the area and has sent specialised leak teams to the region trying to investigate the problem.

The company said that it is very cognisant the coming weekend is a big sporting weekend in the capital and that the St Patrick's Day is the weekend after that. 

It said that all of its actions are aimed at ensuring that there is enough water so that normal economic activity will not be disrupted.

The matter was raised in the Dáil this afternoon and Minister Eoghan Murphy said Irish Water hopes most issues will be resolved by the end of this week, with the exception of the Tipperary situation.

In a statement, Irish Water said that a 'Do Not Drink' notice it issued for the Fethard area remains in place until further notice. It said it expects this notice to remain in place for a number of weeks.

The company said that it is working with Tipperary County Council to return a supply of water for sanitary use only over the coming days.

Around 3,000 people in the Eyrecourt, Laurencetown, Kiltormer and Clonfert areas of Co Galway have no water supply.

Irish Water says that alternative water supplies are available in these areas and it has urged customers to conserve water.

The company also said that water restrictions will again be in place in Tír an Fhia, Carraroe, Williamstown, Moylough, Clonbur/Cornamona, Eyrecourt, Laurencetown, Kiltormer and Clonfert.

Irish Water is asking those who have problems with their water supply to phone its helpline 1850 278 278.

There is also a special help line for members of the Oireachtas 1890 578 578.

There is a separate helpline number for county councillors and local representatives to contact it on 1890 178 178.
