Sewerage charges relate to the cost of delivering sewerage services – collecting, transporting, treating, recycling and disposing of used water. Charges are based on the capital value of your property, which is set on an annual basis by the Valuer-General’s Office.
Increases to sewerage charges in 2023-24 will be capped at 4.8 per cent on average (subject to rounding). Property rates are set using 2023-24 property values determined by the Valuer-General’s Office.
Calculating your quarterly sewerage charge
Sewerage charges are formed by applying a rate in the dollar to the value of your property. This means the number of cents charged per $1,000 of property value, subject to a minimum charge for 2023-24 of $79.50 per quarter.
To work out your sewerage charge, divide your property value by 1,000. Then multiply that number by the rate that applies to you (using the rates below). To calculate an annual charge, multiply by four.
If the result is lower than the minimum charge, then the minimum charge of $79.50 per quarter or $318.00 annually will apply.

Charges if you are not connected to the sewerage network
If your property can be connected to our sewerage network, you are billed a rating on abuttal charge. This is regardless of whether you use this service or not.
A rating on abuttal charge reflects the availability of the service should you or future owners choose to connect it to the property. The sewerage network has been designed to make this connection available, which adds value to your property.

How we set our sewerage prices

- When setting prices, we consider many factors including the cost to operate, maintain and improve how we deliver a reliable water supply, dependable sewerage service and increase the use of recycled water for community benefit.
- The South Australian Government is committed to state-wide pricing and the principles outlined in the National Water Initiative.
