A shared water meter is when one common meter services a group of properties. This is also called common supply.

You can find shared meters at:

  • strata titled residential units
  • properties within a retirement village
  • other shared residential spaces

Water use charges

Water use charges are often billed to the property manager who then divides the costs between individual owners. This is at the discretion of management.

We base the water use charge on the total amount of water used across all residences. Our meter readers visit every 2 months to read the meter and record the total water use.

Water use tiers

We use a tiered pricing structure to encourage the careful use of water. This means the more water you use, the more you pay.

The amount of water available at each pricing tier is multiplied by the number of residences. This is to ensure you can still benefit from the lower pricing tier.

For example, 10 residential units with a shared meter would have the following water use pricing tiers:

 
Individual property use (based on one residence with one meter) Common supply water use (Individual use x 10 residences) Price per kilolitre (based on Perth metro tiers)
0 - 150 kL 0 - 1,500 kL $1.859
151 - 500 kL 1,501 - 5,000 kL $2.477
over 500 kL over 5,000 kL $4.633

Water service charges

This is a fixed charge to supply clean drinking water to residential properties. This charge also contributes to securing and maintaining water sources. The water supply charge is $268.98 for the 21/22 financial year for all residential properties.

Service charges are usually billed to the individual property owner. Where we bill one account for a group of residences, we multiply the service charge by the number of residences. 

For example, 10 properties x $268.98 = $2,689.80

Sewerage service charges

This is a fixed charge that covers the cost of removing, treating and discharging the water that goes down your drains and toilets. This charge also contributes to the cost of maintaining the wastewater pipe network.

Where we bill one account for a group of residences, we multiply the sewerage charge by the number of residences serviced by that meter. We base sewerage charges on the gross rental value (GRV) of the property.

Drainage service charges

This charge only applies to properties in the Perth metro area that fall in a drainage catchment. This charge helps cover the cost of removing excess storm water.

Where we bill one account for a group of residences, we multiply the drainage charge by the number of residences serviced by that meter. We base drainage charges on the gross rental value (GRV) of the property.

FAQs

Sub meters can be installed in multi-residential developments with three units or more. Sub meters will record the water use of individual properties. This means customers can be billed for their own water use, rather than the average water use of the group of properties.
