Nampa Leak Check Request and High Water Bill Steps
If your Nampa utility bill suddenly increases, check the official leak check request route before assuming the bill is wrong. Water and sewer charges are commonly linked to consumption, so a running toilet, irrigation leak or underground leak can raise the bill quickly.
| High-bill clue | Possible cause | First action |
|---|---|---|
| Usage jumped suddenly | Running toilet, irrigation leak, outdoor hose or hidden plumbing leak. | Check toilets, irrigation system, hose bibs and meter activity. |
| Water use seems continuous | Leak after the meter or irrigation issue. | Request a leak check using the City link or call Utility Billing. |
| Bill includes sewer/trash too | Combined utility billing can include water, sewer and trash. | Separate each line item before calling. |
| Irrigation amount unpaid | Irrigation charges may have separate delinquency rules. | Check due date and call Utility Billing before penalty/interest issues grow. |

| Not saving confirmation | It is harder to resolve posting or account disputes later. | Save receipt, confirmation number and screenshots. |
