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


Shared meters are common in:

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

Water use charges

Water use charges are often billed to the property management who will facilitate the distribution of costs to individual owners. This is at the discretion of the management.

For properties serviced by a shared meter, the water use charge is based on the total amount of water used across all residences. Our meter readers visit the property approximately 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.

For properties with a shared water meter, the amount of water available at each pricing tier is multiplied by the number of residences. This is to ensure that customers still benefit from the lower pricing tariffs.

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

 
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 - 1500 kL $1.827
151 - 500 kL 1501 - 5000 kL $2.434
over 500 kL over 5000 kL $4.553

Service charges

Service charges are most commonly billed to the individual property owner. Where we bill one account for multiple residences, we multiply each service charge by the number of residences.

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 $264.35 for the 19/20 financial year for all residential properties.

Where we bill one account for multiple residences, we multiply this charge by the number of residences.

For example, 10 properties x $264.35 = $2643.50

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 with multiple residences, we multiply this charge by the number of residences serviced by that meter. Sewerage charges are based on the gross rental value (GRV) of the property.

Drainage service charges

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

Where we bill one account with multiple residences, we multiply this charge by the number of residences serviced by that meter. Drainage charges are based 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.

There are many ways you can save water. Limiting your showers to 4 minutes or less, not leaving the tap running when brushing your teeth and installing a dual flush toilet are all great water saving ideas.
