Water Corporation.
Total water abstracted from reservoirs for public water supply within the Perth region is equal to the total annual water released from the reservoirs during the reporting period. The water volumes released from the reservoirs are metered at the outlet continuously and reported on a monthly basis.
Expected error for water meters is +/- 5%.
The Department of Water requires that all water meters, when tested in situ conditions, must be within 5% accuracy across the full flow rate range (Department of Water 2009).
