Advantage by the Numbers

Learn more about how we reached these numbers
Yes. Calculations are based on industry averages and assumptions for positive displacement meter accuracy.
Yes, you can put additional annual costs in the ‘Other’ rows for cost input. Make sure the cost is per unit.
This calculator was developed with data from 5/8” residential Neptune meters.
Neptune does not guarantee calculator results. Estimates are based on tests and average industry data. Meter performance may vary depending on factors like water quality and field conditions. More accurate inputs from your utility yield more reliable estimates.
