I also was shocked by this.Each unit is separate meters.

Go to my profile page and look on the right side for my blogs, read "How to develop a good BS Meter" that tells you why you need and education in the basics of real estate.You will never paint a master piece with a paint by numbers set. 

Hopefully individually metered to tenants.

If you have doubt, have a plumber meet you at the place and turn the water on at the meter, let him take a look.

I have a duplex where the tenants get the monthly water bill from a metering service, and the tenant sends the payment to me.

Very interesting property to say the least.Owner pays all utilities, they are not metered separately.

I don't think it would register on the appraisal meter.

Head office: area size 147 square meters, construction floor 707 square meters2.

Then we had a completely unrelated pressure breakdown in the main supply & we discovered the large 1960's era shut off valve on the city side of the water meter was also heavily corroded inside.

The biggest problem was that the deck was built on top of the gas meter.
