Took our meter number to the office behind the PTT - the lady made a phone call and we duly paid our water bill for the apartment.
At the same time, we paid our communal water for the pool (one of our neighbours has it on their meter).

I think that someone did not pay the water last year, which might explain the cubic mtrs, but even so the bill was 3x more than we would normally have paid for 1 season. The lady did ask if it was for a pool. 91.50 lira was for the waste water (atiksu) - a bit of a con, when most of the water went in the pool and not down the toilet :
