Sewerage prices

Sewerage prices

Sewerage charges relate to the cost of delivering sewerage services – collecting, transporting, treating, recycling and disposing of used water. They are based on the capital value of your property, which is set by the Valuer-General on an annual basis.

Calculating your quarterly sewerage charge

Sewerage charges are worked out by applying a rate in the dollar to the value of your property. This means the number of cents charged per $1000 of property value, with a minimum charge for 2019-20 of $80.80 per quarter.

To work out your sewerage charge, divide your property value by 1000. Then multiply that number by the rate that applies to you (see below for the rates). To calculate an annual charge, multiply by four.

If the result is lower than the minimum charge, then the minimum charge of $80.80 per quarter or $323.20 annually will apply.

Disputing the valuation of your property

To enquire about valuations set by the Valuer-General or to make an objection to your property valuation, please contact the State Valuation Office:

Charges if you are not connected to the water network

If your property is able to be connected to a water main, you are billed a rating on abuttal charge. This is regardless of whether you use water or not.

A rating on abuttal charge reflects the availability of the service should you or future owners choose to connect the property. The water network has been designed to make this connection available, which adds value to your property.
