A higher water bill deserves an explanation, but the total due is a poor place to start. Separate the amount of water billed from rates, fixed fees, and the length of the billing period. A 42-day bill and a 30-day bill can look different even when daily use is similar.
Place the current bill beside several prior bills. Confirm the service address, account, meter number, read dates, billed volume, units, and whether the utility used an actual or estimated read. Divide volume by billed days for a first comparison. Keep the raw totals too, so the owner can see exactly how the daily figure was calculated.
Check what changed at the property
A tenant opening, longer operating hours, irrigation schedule, cooling demand, or cleaning program can change water use. Compare the timing of each change with the meter period. If the site has submeters, use them to narrow the question to a suite or system. First confirm what each submeter actually covers.
Season matters. Irrigation can make a summer comparison with a winter month misleading. A property with process water may need a different baseline from an office building. Do not label a single spike “a leak” before checking the bill and operating history. If the billed volume appears wrong, ask the utility to explain the read or account change.
Investigate an unexplained increase
EPA's WaterSense guidance recommends active water-use monitoring and covers metering, submetering, leak detection, and benchmarking. These practices help organize a property review. They do not tell you what happened at this building. If the volume is still unusual after checking the bill and known changes, have the responsible building team or qualified vendor inspect the affected systems.
Give the investigation an owner. Record what was checked, the result, and when the next reading will be reviewed. If an issue is found, retain the repair scope and evidence of the current condition. An invoice for a plumbing visit does not by itself show that usage returned to its prior pattern.
Make the next report useful
The owner report can fit on one page: the bill period and meter, total volume, volume per day, comparable periods, known property changes, what remains unexplained, and the next action. If a utility correction is pending, say so. Do not book expected savings or call the issue resolved while the meter history is still unclear.
EPA's commercial facility resources offer tools for understanding water-using processes and planning a broader review. Use them after the immediate bill question is framed. They provide methods, not a savings forecast for your property.
If utility changes disappear into a monthly statement without an explanation or follow-up, Request a Property Management Performance Review.
