I don't get the deal with the water restrictions for domestic properties. I've been told domestic properties account for 2% and another person quoted 8% of total water usage and industrial, commercial, government etc etc account for the rest. Why don't they restrict them a bit more, surely it would be easier. I know they need to use water but there is a lot more that can be saved compared to the small amound used by households.
Also when they really clamped down on the restrictions here water useage went up!!! This was mainly due to the fact that people were making sure they were watering on the days they could instead of doing it when they could be assed or remembered. And now they are telling people to dob in their neighbours, surely this will make everyone more friendly
Anyway I think just pressure wash it in the back yard, its not like you will be doing it for hours and you can always make up a good story if you get a special visit like you were bathing the cat.....
