Terms of use

Last updated 29 September 2026.

WaterBalanceCalc is a free tool provided by Aqua Analytics Australia Pty Ltd. By using it you agree to the following.

No warranty

The calculator implements published methodology in good faith but is provided as is. Results depend entirely on the data you enter and on estimates whose uncertainty can be large. Do not commit capital or make regulatory submissions on the basis of these results without independent verification, including field measurement of real losses.

The AI assistant

Suggested values from the assistant are generic starting points, not advice about your system. You are responsible for reviewing anything you accept into your balance and for any narrative you share.

Acceptable use

Don't attempt to disrupt the service, scrape other users' data, or exceed reasonable use of the assistant. We may limit or suspend access that does.

Attribution

The methodology follows the IWA Water Loss Specialist Group and the WB-EasyCalc / WCB-EasyCalc lineage. The site's code and content are © Aqua Analytics Australia Pty Ltd. You may use your own results freely, including in reports, with or without attribution.

Changes

We may update these terms; continued use after a change means you accept it. Questions: hello@waterbalancecalc.com.
