Recently I bought a 2BHK flat in KPHB, Hyderabad. The Builder has constructed two huge sumps to store manjeera(dam) water and a huge sump for bore water. Now as this is summer and that too it is hyderabad, most of the place is in shortage of bore water and even municipality is not releasing the dam water for more than 2 hrs which will hardly fill only half of the one huge sump.

Hence we are ordering tankers of water. The builder has set up 20 tanks for 20 flats of 1000 litres each. But the logic behind is that if the pipe is kept in one tank and if it filled up, the water will go in to the next one and so on. Like this every alternate day the water is being filled in 20 storage tanks. The problem is that every municipality water tank(capacity of 14000litres) costs Rs. 800 and as we are ordering alternate days, it is costing Rs. 700 extra burden for each flat besides the normal maintainence of Rs 700/- .

Some tenants are not willing to pay this as they are saying we don't use much water.

I got the idea of water meter. I think by making the 20 individual tanks to one common tank and keeping water metre for every flat will be a better idea. But we don't know how much to charge for a unit. Could you please help me in this regard?
