Have you been overcharged for your water?
Unless your water is metered it is difficult to tell whether the
supplier has definitely overcharged you or not. However, suppliers
have been reprimanded in the past for billing customers up to 10
times what they should have been paying.
Customers do receive refunds if they've been paying too
much for their water. So if your bill seems unusually high
then it is well worth contacting your supplier about it.
