Commercial water prices
Commercial water prices
Commercial properties include retail trade (shops, shopping centres, department stores and general stores) and wholesale trade (distributors and warehouses where goods are purchased and stored in large quantities, then on-sold to retailers or sellers.) It also includes finance, real estate, construction and repair services, and a range of personal and business services.
We have minimised the increase in water charges while still investing in the services our business customers need to keep costs as low and stable as possible in South Australia.
Water charges are made up of two parts:
- A fixed charge for water supply.
- A variable charge for water use – the more you use, the more you pay.
Water supply charge
For commercial properties with a property value less than $10 million, the 2025-26 fixed rate is $329.20 per year, billed at $82.30 per quarter.
For properties valued at more than $10 million, a property-based charge also applies. In 2025-26 the quarterly rate applied to commercial customers is $0.12950 per $1,000 of property value above $10 million.
Water use price
The 2025-26 water use price for commercial customers is now $3.365/kL (or $0.003365 per litre).
