[Avodah] If you have an electronic water meter, can you turn on your faucet on Shabbos?

[Simon Montagu]

With reference to the question of whether adding to one's water bill
is niha leih or not, perhaps the end of the first Mishna in AZ is
relevant:

"Rabbi Yehuda 'omer nifra`in mehem mip'ne shehu metzer. 'am'ru lo --
af al pi shehu metzer achshav, sameah hu le'ahar miken".

It's not exactly the same case, but maybe similar.
