Case study 13 – MyVoltage identified a faulty council bulk meter and resolved excessive water billing
A residential complex faced an unusually high water bill and struggled to understand the cause. With MyVoltage’s detailed sub-metering data, we were able to investigate and pinpoint the issue, ultimately uncovering a faulty council bulk meter that had been the source of the problem for years.

The challenge
The complex’s water bill was excessively high, and despite their efforts, they could not identify the source of the discrepancy. Without the right data, they were unable to address the issue and continued paying inflated bills.
The solution
By analyzing the data from all the sub-meters and reconciling it with the bulk water meter, we identified a fault with the council’s bulk meter. This faulty meter had been inaccurately measuring water usage for years, leading to inflated bills.
The results
Our detailed analysis and fault detection enabled the complex to approach the council and initiate the process of securing a credit for several million rand. The credit is still being processed, but the investigation has provided clarity on the cause of the excessive charges.
Why this matters for property managers
Water billing errors can go undetected for years, placing unnecessary financial strain on residential complexes. Without accurate data and expert analysis, property managers may unknowingly pay inflated utility bills. MyVoltage’s smart metering solutions provide the insight needed to detect faults, challenge incorrect charges, and secure refunds—ensuring fair and accurate billing for property owners and residents.
Key takeaways
Smart metering systems provide the data needed to identify and resolve billing issues. With accurate readings and thorough analysis, we were able to identify a faulty bulk meter, leading to the potential for significant savings once the credit is finalized.
Are you certain your utility bills reflect actual consumption? Let’s investigate.
