Applicable Water charges for the premises with dedicated water mains
"Since the buildings/Premises which or provided with dedicated water main are privileged to get more quantity, they cannot be equated with the other consumers getting water supply from common mains. Therefore the method of dividing the total consumption by number of flats is not applicable to the multistoreyed buildings, special buildings/multi assessed buildings wherein water is supplied through dedicated main. Hence, the charges at the applicable rates should be claimed for the total quantity of water supplied to building/premises with dedicated main"
