What to Do If Your Golden State Water Bill Looks Too High
High water bills are often caused by running toilets, irrigation leaks, outdoor watering, hidden plumbing leaks, water softener or pool fill usage, billing-cycle changes or a missed previous payment. Start with a simple leak check before assuming the bill is wrong.
| High-bill clue | Possible reason | First action |
|---|---|---|
| Sudden usage jump | Running toilet, hidden leak, irrigation issue or outdoor hose left on. | Turn off all water and check whether the meter still moves. |
| Summer bill increase | Landscape irrigation, dry-weather watering, pool fill or longer outdoor use. | Check sprinkler schedule, broken heads and conservation resources. |
| Payment looks missing | Wrong account number, delayed mail, portal issue or third-party payment problem. | Collect confirmation number, receipt or check copy before calling. |
| Past-due notice received | Payment did not post before the due period or account has old balance. | Call 1-800-999-4033 and ask what amount is needed to protect service. |
| Water quality or pressure concern | Local service condition, plumbing issue or service-area work. | Call customer service and check your service area updates/water quality resources. |
