The Irish Water are urging people to conserve water, despite some rainfall.
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 currently 24,000 people across 22 water supply schemes around the country who are experiencing a restricted or intermittent water supply.
