Master and subsidiary meters

We are responsible for the pipe between the public watermain in the road, and the master meter. 

The property owners are jointly responsible for the water pipe between the master and sub meter. Each owner is responsible for the pipe between the sub meter and their dwelling.

See Who is responsible for pipes?

Each property receives a bill for their own use through their sub meter. We then add up the usage from all the sub meters and compare this to the master meter usage. The master is the first in line so will capture all usage going through the private network.

If there is a difference in usage then each dwelling that is connected via the master will receive an equal share of the usage.

Example:

Network of master meter and three sub meters (kL = kilolitre):

Usage for network is master 36 kL, sub 1 = 15 kL, sub 2 = 8 kL, sub 3 = 10 kL
Total usage for all sub meters = 33 kL

Calculation:
Sub 1 = 15 + ((36-33)/3) = 16 kL
Sub 2 = 8 + ((36-33)/3) = 9 kL
Sub 3 = 10 + ((36-33)/3) = 11 kL

Total network usage = 36 kL (16 + 9 + 11)
