Water meter facility in high rise apartments

Hi,

I have booked flat in a high rise apartment(10 floors) which is under construction. We owners are planning for water meter facility for every flat. The builder saying that it is not feasible in any high rise apartment. Is it true?

But the builder says he can try/will do if we show him any high rise apartment with water meter facility in Bangalore.

Any body has any input on this?

Any body knows any high rise apartment with water meter facility installed.
