Water levels in Lough Owel are at a historically low level.
Over 50 thousand Irish Water customers in Westmeath are under a water conservation order from today.
The Uisce Eireann move also affects residents in parts of Meath and Donegal.
The affected areas in Westmeath include, Mullingar, Moate, Rathowen, Kinnegad, Milltownpass, Multyfarnham, Tyrrellspass and Kilbeggan.
It's due to the Lough Owel water supplies coming under severe stress due to dry weather and steady demand.
Falling levels in Lough Bane mean that communities in Kells, and Old Castle are under a conservation order as well.
Lough Owel in Mullingar is at its lowest level in 50 years.
Businesses are being asked to conduct water audits to see where savings can be made, while household tips are available on Water-dot-ie.
