Ah ok that makes sense, the UK will probably follow suit eventually.More people in the household raises the amount of allowable water usage before the higher tier price per gallon kicks in. The water part of the bill isn't a major problem until they add in the sewer and trash pick-up monthly charges.
Landscape watering has to be kept to a minimum though.
We go by cm3 and not gallon’s.
With regards to sewerage, you get customers who do a lot of gardening wondering why they are charged the same amount for water usage for their drainage charges as they are their fresh water. Usually they have read something on a forum and they call determined to be billed separately. Doesn’t happen though, but I see their point.
I can imagine the drought caps have hit businesses like landscaper’s hard. When I think of USA, I think of big gardens and water sprinkler’s. Just from the movies.
