Comment Utility not auditing it's service (Score 4, Insightful) 65
The most concerning part should be that the utility isn't auditing it's service. The most basic check is to compare water pumped or otherwise brought into the system against water usage billed to customers. Those two numbers should be equal, any discrepancy indicates leaks or other unaccounted-for draws. Any discrepancy should also be relatively stable, with any large variations correlated to known main breaks. You especially audit things immediately after a major change like bringing smart meters on-line to catch problems like this.
