A hosepipe ban will remain in place in the midlands until July 21st.
The recent rainfall is not enough to restore water supplies in the midlands.
The levels in Lough Owel, which supplies 50,000 customers in Mullingar, are now the same as during the drought of 2018 - with Mullingar and Castlepollard water schemes at risk of going into drought.
In Laois, schemes in The Swan, Ballyroan, Mountmellick, Portlaoise, Rosenallis are also at risk of drought - while Dunkerrin and Mountbolus are at risk in Offaly.
Irish Water's ban on hosepipes remains in place until July 21st.
