Work continues to restore water
The number of houses without water in Northern Ireland is down to 799.
The main affected areas are parts of Cookstown, Dungannon, Newry and Warrenpoint, and some 500 staff are dealing with those properties. Work will continue to restore supply to those caught up in the burst pipes crisis, some of who have been without running water for almost two weeks.
Overnight an additional 60,000 homes were cut off temporarily to allow depleted reservoirs to refill. Some progress was made on Saturday reconnecting properties left without any water, with more than 4,300 getting supply back.
But with water still pouring out of leaks in the system, under-fire Government-owned utility Northern Ireland Water (NIW) extended its on/off rotation system to other homes overnight in order to replenish reservoirs despite earlier expressing hope that the rotation would soon be discontinued.
It is expected that water supplies will continue to be constrained for a limited period overnight.
This will affect no more than 45,000 properties across the east of Northern Ireland. Reservoir levels in the greater Belfast area remain low. The focus is on continuing to build up water supplies in the Belfast reservoirs ahead of Tuesday's return to work.
While 500 NIW staff battled round the clock to restore supplies to the region's crippled system, vandals were blamed for emptying out almost 5,000 gallons of water from temporary tanks in one of the badly hit areas in Coalisland, Co Tyrone. People arriving at bowsers at the Gortgonis Park centre to collect drinking water on Saturday morning found that the valves had been opened overnight, and NIW replaced the tanks in the afternoon.
Arctic weather conditions, followed by a sudden thaw, caused large numbers of burst pipes in buildings and in the mains supply, draining unprecedented amounts of water from the system.
Louth County Council in the Republic of Ireland has agreed to supply water from its treatment plant in Dundalk to its neighbouring local authority across the border in Newry and Mourne. The development came as the Scottish Executive continued to supply Northern Ireland with thousands of litres of bottled water to help cope with the crisis. However, many of the leaks are understood to be within unoccupied homes and businesses and NIW has urged customers to check their properties and repair any bursts as soon as possible.
Stormont's Regional Development Minister Conor Murphy has set up an independent probe to examine the causes of the crisis, but insisted that restoring water supplies to homes and businesses remained the first priority.
