How Bill is Calculated

View the rates and see how we calculate your bills.

The System calculation of Bills is solely dependent on the amount (Volume) consumed regardless of the number of Days, within a billing period.                                                                                   

There are two Volume categories: Band-1 and Band-2.                                                         

The Bill is calculated according to the Band in which the Volume consumed falls in.

 For example: Customer consumes 75kL within a month                                                                                                                

The first 15kL @ Band-1 (15x1.50=K22.50), the next 60kL @ Band-2 (60x8.00=K480.00)
Thus the charge would be:        K22.50 + K480.00 = K502.50 (Add 10% GST = K552.75)


If the customer is connected to the Sewer, the same principle applies
The first 15kL @ Band-1 (15x0.50=K7.50), the next 60kL @ Band-2 (60x3.00=K180.00)
Thus the charge would be:        K7.50 + K180.00 = K187.50 (Add 10% GST = K206.25)

The total invoice charge now would be: Water Charge + Sewer Charge
                                                        K552.75 + K206.25 = K759.00 Total Payable
