Irish Water has outlined the water restrictions that will come into effect in Dublin next week as efforts to conserve supply continue.

There will be 34 areas around the Greater Dublin region that will experience a reduction in water pressure between 10pm and 5am.

In a statement, the company said the reduction will be such that water will reach the ground floor of a two-storey house.

Most households will experience low overnight pressure, but no loss of supply overall.

However, some customers on high ground and at the end of networks may see pressure reduce to a trickle at kitchen sinks during those periods.

People living in apartment blocks and other multi-storey buildings may experience low overnight pressures depending on the pumping and storage system in their building.

Irish Water has said there will be no daytime restrictions to water supply in the Greater Dublin area.

Restrictions affecting a further 25 water schemes across the country will continue to be implemented. 

A full list of affected areas can be found on the Irish Water website.

It comes as there has been no significant rainfall for more than 40 days and none is forecast for at least ten more days.

Irish Water Engineer and Corporate Affairs Manager Kate Gannon said: "Introducing restrictions was an option that Irish Water hoped could be avoided because of the inevitable impact on homes and businesses.

"The decision to lock down the restrictions to these areas was not taken lightly.

"If any customers are being adversely affected can they please call the Irish Water Customer Care line on 1850 278 278 and this will allow us to identify any areas where an undue impact is being felt."

Ms Gannon also appealed to people to continue to conserve water.

The following areas will experience low pressure overnight:

City Centre, Smithfield, Phibsboro, Drumcondra, Cabra, Whitehall, Finglas, Beaumont, Marino, East Wall, Inchicore, Crumlin, Ballyfermot, Kimmage, Walkinstown, Chapelizod, Ranelagh, Rathgar, Ballsbridge, Donnybrook, Sandymount, Ringsend, Clondalkin, Lucan, Tallaght, Templeogue, Ballyboden, Rathfarnham, Dalkey, Killiney, Ballybrack, Shankill, Cabinteely and Bray

Speaking earlier on RTÉ's Morning Ireland, Ms Gannon said even if we had two weeks of solid rainfall it would be soaked up by the ground.

"We need to get the soil/moisture deficit to over 10ml to get water levels to begin to rise," she said.

Ms Gannon also said that there is a base amount of water that is used over a 24-hour period of time.

She said that some of it is usage and some of it is leakage, and that reducing water pressure overnight serves to reduce both.

A status yellow drought advisory warning has been extended to 3pm next Wednesday, 18 July, by Met Éireann.

The weather forecaster said that while there will be small amounts of rainfall over the coming days, it will not be sufficient to reduce soil moisture deficits.

The country has experienced dry conditions since 21 June and, despite some very light rain in parts, drought conditions persist.

More changeable weather is forecast from the middle of next week.
