Around 2,500 properties have been left without water as industrial action by NI Water staff continues.
In a statement NI Water said it “regrets as many as 2,500 properties in Counties Tyrone, Londonderry and Fermanagh may have suffered disruption to their water supply due to ongoing industrial action”.
Normal out-of-hours repairs are not being carried out because of the dispute over pensions.
The company said it would try to minimise disruption, but resources were limited. The company has a postcode search on its website for customers to check for more information.
The areas affected include:
Carrickmore, Dungannon (Sultan Road), Glenhull, Greencastle, Loughmacrory, Mountfield, Omagh (Camcosy Road, Gorticashel Road, Cairn Road, Cloghan Road, Fernagh Road, Green Road, Striff Lane), Pomeroy (Camlough Road and Loughmallon) and Sixmilecross.

The statement added: “NI Water fully recognises this is a frustrating experience for our customers, and can assure them we are doing everything possible to restore water supplies as quickly as possible.
“NI Water would like to once again thank our customers for their continued patience whilst this problem is being resolved. Despite the fact the company has in place contingency plans to minimise disruption due to the industrial action, resources available to NI Water, out of normal working hours, remain very limited. As a result service levels have been impacted, in particular in relation to responses to emergency situations.
