Some 600,000 people are affected by restrictions in the greater Dublin area
The Irish Water utility is continuing to urge people to conserve water, despite some rainfall.
It says many raw water resources around the country are significantly depleted and continuing to drop.
In the greater Dublin area there are around 600,000 people affected by restrictions.
Irish Water say: "These customers are not seeing any discernible impact.
"The pressure management is being fine-tuned, using the learnings and customer feedback from when pressure management was used during Storm Emma.
"This has ensured minimal disruption, including areas with high night-time use."
There are also 24,000 people across 22 water supply schemes around the country who are experiencing a restricted or intermittent water supply.
This includes Clare, Cork, Donegal, Galway, Kerry, Kilkenny, Limerick and Offaly.
Irish Water say the number of people affected "has doubled" since restrictions were first introduced.
But the utility adds: "The schemes are reviewed on a daily basis and restrictions are only put on if necessary."
It also says "significant works" are ongoing to try to support the supply of water in these areas.
They are currently having water tankered to reservoirs or water sources to minimise restrictions.
Irish Water's corporate affairs manager Kate Gannon says: "Raw water resources are significantly depleted and continue to drop.
"In the absence of significant rainfall amounts, Irish Water continues to be concerned about the water resources into August and September.
"Water conservation efforts by Irish Water, the local authorities and our customers need to continue at their current levels."
