People will be banned from using hosepipes from tomorrow in a bid to conserve water.
It comes following the driest May in 170 years.
At the moment, 77 of Irish Water's 900 drinking water schemes are in drought or at risk of going into drought.
It follows the driest May recorded since 1850.
Irish Water spokesperson - Tom Cuddy - says it's pushed their supplies to the limit.
To combat this, using garden hoses and other non-essential uses of water will be banned from tomorrow.
Using a hosepipe for just one hour is the equivalent of the daily water usage of an average family.
Managing Director of Irish Water Niall Gleeson, says they can fine people for not obeying the ban, but he's hoping it doesn't come to that.
People are being advised to use a watering can for the garden and a bucket and sponge to wash cars.
The 6-week hosepipe ban will remain in place until midnight on July 21st.
