MAINTENANCE We have 4 spare meters in case any meter malfunctions Recorded the meter readings for one month Calculated the unit price per litre Arrived at an average usage per flat per month A tariff has created being the average as pivot Flats usage crossing this pivot will be charged double the unit price
MAINTENANCE continued Meter reading will be recorded every 15 days Every month bills will be generated on the actual usage per month + base cost Base cost includes expenses for other operations like security, house keeping, AMC’s etc. Bills will be dropped in all mail boxes before 1st of every month The maintenance should be paid before 5th of every month
