Sewerage prices
Sewerage prices
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 Office of the Valuer-General.
The rates used to calculate sewerage charges are updated every year and take into consideration the general movement in the property market. This ensures the increase in total revenue from sewerage charges does not provide a gain to us due to increases in the value of properties.
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 2025-26 of $94.00 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 $94.00 per quarter or $376.00 annually will apply.
Quarterly rates per $1,000 of property value
| Residential (metropolitan) | $0.14750 |
| Residential (country)* | $0.22800 |
| Non-residential/commercial (metropolitan) | $0.228250 |
| Non-residential/commercial (country)* | $0.353250 |
*Country sewerage prices apply to properties within SA Water defined sewerage drainage areas.

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.
