Millions of people across the East and South East of England now face a fine of up to £1000 if they use a hosepipe to water the garden or wash cars.
Anglian Water, Thames Water and Veolia Water are among seven companies who have brought in a hosepipe ban after two really dry winters which have left reservoirs really low.
The ban is starting though after a week that's seen rain fall across many parts of Eastern England.
Peter Simpson, Managing Director of Anglian Water, said: “The fact is that it simply has not rained anywhere near enough.
“Two dry winters have prevented rivers, reservoirs and aquifers from refilling with the water we treat and supply during the rest of the year, especially during the hotter months when demand rises.
“We cannot know how much rain the rest of the year will bring and that’s why we believe a domestic hosepipe ban now is the most sensible and responsible action to take to help safeguard customer supplies for this year, next year and beyond.”
Here's what you can and can't do now the ban has come in
