Update 5.06pm: Irish Water says it is temporarily lifting water restrictions in North County Dublin as water levels have risen.
People in the area have been struggling to wash, cook and clean for almost a week because of low supplies.
Irish Water has warned that the restrictions will most likely have to be enforced again tomorrow night.
Local councillor Tom O’Leary said the issue will be discussed at Fingal County Council’s monthly meeting this evening.
Update - 9.32am: Water supply for the greater Dublin area is "on a knife edge".
The General Manager of Irish Water is warning that treatment plants are working at full capacity at the moment with nothing to spare.
Irish Water's Eamon Gallon says they are watching the situation closely.
He said: "We should have spare capacity of 20% so that anytime we have a peak in demand we can supply it.
"But at the moment our five main water treatment plants are working near full capacity.
"Ultimately the solution is to bring water up from the Shannon."
6.56am: Irish Water turn on full supply for four hours in Skerries, hope to extend that in coming days
Efforts are continuing to sort out water shortages in Skerries in North County Dublin this morning.
Irish Water is asking people in the area and in the Loughshinny, Skerries Road and Rush areas to continue conserving water for the foreseeable future.
The utility is going to turn the full water on this morning from now until 10am this morning to allow tanks in homes and businesses to fill.
Irish Water Head of Customer Operations Yvonne Harris hopes to extend this in the coming days.
Ms Harris said: "At this point in time, our engineers are assessing the water levels. We hope over the coming days we'll extend the amount of time that water is going to homes.
"Today it still from 6am until 10am, we hope that we will be able to extend that through longer periods during the day until we can fully restore full supply to all of our our customers."
