How to Measure Water Loss in Estates & Private Networks
Make water-loss decisions from comparable measurements. Start with a baseline, investigate the gaps and review the effect of repairs over a period that represents normal operations.
Define the measurement boundary
Identify the supply entering the property or zone and every measured use within that boundary. Record storage changes and legitimate unmetered services that may affect the comparison.
- Bulk supply and zone meters
- Customer and shared-service readings
- Storage and known unmetered uses
Compare equivalent periods
Align reading dates before calculating a difference. Delayed reporting, billing estimates and changes in occupancy can make an apparent loss misleading. Record the assumptions alongside the figures.
- Consistent reading periods
- Data completeness and reporting delays
- Occupancy and supply schedule changes
Turn unusual patterns into inspections
Persistent flow during idle hours or a sudden increase can guide maintenance checks. A reading alone does not establish the leak location. Field investigation confirms whether the cause is a physical leak, an unmetered use or an accounting issue.
- Alert thresholds matched to normal use
- Inspection and repair records
- Responsible operators and escalation steps
Measure recovery after corrective work
Compare the post-repair period with a relevant baseline and note changes in operating conditions. Report measured water volume separately from its financial value, using a consistent cost or tariff assumption.
Use MajiSure’s savings calculator to explore a scenario, then replace assumptions with site measurements. A planning target is not a guaranteed result.
- Measured volume recovered
- Comparable before-and-after periods
- Clear value assumptions and ongoing follow-up
