Irish Water has announced a hosepipe ban for the whole country.
The measure has been in place in the Greater Dublin Area since the start of the week - but will be extended nationwide from Friday at 8am.
The order bans the use of water for non-essential activities like watering the garden or filling a paddling pool and will continue until the end of the month.
Irish Water say the decision has been made because of the drought conditions, which are due to continue into next week.
They're encouraging people to keep conserving water to help protect water supplies.
The Ballinasloe Water Treatment Plant is operating at full capacity and reservoir levels are giving major cause for concern. Supplementary pumps have been deployed due to low water levels in the River Suck, which are decreasing at a significant rate. Customers in Ballinasloe, Laurencetown, Eyrecourt and Kiltormer are urged to reduce water usage in every way possible to ensure a continuous supply for all.
Night time restrictions on Inis Mór and Inis Oirr will be extended from 8pm to 8am daily commencing on Friday, July 6. Water usage on Inis Mór has increased by 30 per cent in the past 21 days and reservoir levels are giving cause for very serious concern.
Water consumption on Inis Oirr and Inis Meain has increased by 30 per cent in the past two weeks and Irish Water is urging customers to increase their efforts to conserve water on all of the Aran Islands.
Restrictions remain in place on the Ballyconneely Water Treatment Plant serving the Ballyconneely and Foreglass areas from 11pm to 7am for the foreseeable future. This is because demand on this scheme is now exceeding supply.
Demand in Tír na Fhía/Leitir Mór has increased significantly and some areas are experiencing outages. Supply from the Tír na Fhía Water Treatment Plant is higher than can be sustained and leak repairs have been carried out in recent days.
Customers in Clarinbridge, Kilcolgan, Roveagh, Ballinderreen and Tyrone Group Water Scheme are urged to conserve water. Work has been carried out at Clarenbridge Water Tower to improve the supply situation in the short term but consumption is still very high.
Customers in Gort are also urged to conserve water as raw water levels in the Gort River are dropping.
Groundwater springs and boreholes supplying Dunmore/Glenamaddy, Kilkerrin/Moylough, Ballygar, Mountbellew and Ballymoe are extremely low and are a cause for serious concern.
Due to very high demand in areas supplied by Tonabrocky reservoir, Irish Water has no choice but to restrict water supply at night time between the hours of 11pm and 7am.
Barna, Moycullen, Knocknacarra, Kingston, Taylor’s Hill, Letteragh Road, Bishop O’Donnell Road, Clybaun Road, Cappagh Road, Ballymoneen Road (areas north of Western Distributor Road) may experience low pressure and reduced flow at night time.
These restrictions are essential to allow the Tonabrocky reservoir storage levels to recover and will remain in place at night time until further notice.
Water conservation appeal
Irish Water is appealing to the Galway public, particularly people working and living in Dunmore/Glenamaddy, Kilkerrin/Moylough, Ballygar, Ballymoe, Williamstown, Tuam, Athenry, Oranmore, Tir an Fhia, Leitir Mór, Tully, Letterfrack, Leitir Mór, Carraroe, Ballinasloe and Galway City to conserve water while the prolonged dry spell that has been predicted by Met Éireann, continues.
