Keeping track of my girlfriend's toilet use

Over 700? How'd you manage that? Do you bathe in an olympic sized swimming pool? Only way you'd do that is if you had a farm and had to irrigate crops.

Damn, Nikki, that's a helluva lot.

Where to do you live? In the middle of the Mojave desert?

$700 is roughly the equivalent of the average annual water bill in the UK, and around half the houses in the country don't have water meters.

We lived in Italy for several years on a farm with a septic tank system, so we didn't pay sewerage charges. Family of three with pretty normal hygienic habits, and our typical bill was the equivalent of $10 or so.
