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 Valuer General’s Office.

The minimum sewerage charge in 2020-21 has reduced by 10 per cent and property rates for property based sewerage charges for residential customers have reduced by more than 13 per cent. Property rates are set using 2020-21 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 $1000 of property value, subject to a minimum charge for 2020-21 of $72.70 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 (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 $72.70 per quarter or $290.80 annually will apply.

Quarterly rates

Residential (metropolitan) $0.20625
Residential (country)* $0.30750
Non-residential/commercial (metropolitan) $0.26500
Non-residential/commercial (country)* $0.40150

* 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. The sewerage network has been designed to make this connection available, which adds value to your property.
