High Nampa Utility Bill, Leak Check and Usage Review
Start here: Nampa bills can include water, sewer and trash every two months. A high-looking bill may be normal for a bi-monthly cycle, or it may be caused by a toilet leak, irrigation use, outdoor hose, changed occupancy, estimated bill or repair issue.
Indoor leak check
Check toilets, flappers, faucets, showerheads, under sinks, crawl space, water heater area and damp flooring.
Outdoor / irrigation check
Review irrigation timers, sprinkler heads, hose bibs, outdoor faucet leaks and recent landscape changes.
Request leak check
Use the official Leak Check Request form when usage looks unusual. Call if you have urgent no-water or same-day service issues.
| Problem | Check first | Best next step |
|---|---|---|
| Bill increased suddenly | Toilets, irrigation, outdoor hose, new occupants, longer billing period, sewer tied to water usage. | Request leak check and gather dates, photos, repair notes and usage comparison. |
| No water | Payment status, service start date, outage, repair shutoff, account issue. | Call 208-468-5711 for billing/same-day service; call 208-468-5860 for immediate repair shutoff. |
| Estimated bill | Weather or meter-reading issue may cause estimated water/sewer charges. | Compare next actual reading. City policy says credit may be issued if estimated charges exceed actual consumption. |
| Underground leak | Repair proof, date discovered, date repaired, historic usage. | Protest promptly; policy references a 16-day window after bill presentation for protest. |
