Water Usage ?

[JG65TE]

Ok, Got my water bill. It reckons I use 312 litres per day............

Lets set the scene, I live alone, Dont water the gardens, dont mind a 10 minute shower now and then with a water saver head of course. I use the washing machine maybe twice a week. I just cant see it really. That would mean an average house full would use about 1000 litres a day. Are they actually reading my meter or taking a guess like I have heard of ?

I would like to see other peoples water usage if anyone doesnt mind ?
