Your Austin water bill suddenly jumped: what to do

Short answer

A sudden jump has three common causes: a leak, a meter or reading error, or a real usage change. The leak check comes first because the answer decides which adjustment path fits. We walk it with you, then file the question with Austin Water.

Who this is for

Austin Water customers whose latest bill jumped far above their normal usage with no obvious reason.

The steps, in order

1. Compare the spike against your last 12 months, not just last month.
2. Run the two-hour meter test with all water off.
3. Check toilets, irrigation, and outdoor lines for silent leaks.
4. Tell us what the check found; ATX files the matching Austin Water question.
5. Watch the next two bills and follow up by the request number.

Have this ready

• The bill period that jumped
• Roughly your normal usage
• Meter-test results if you ran one

Common mistakes to avoid

• Calling it a leak without the meter test; the wrong label sends the request down the wrong path.
• Ignoring a running toilet; it is the most common silent leak and the cheapest fix.

Common questions

How do I check for a water leak at home in Austin?

Turn every water use off, read the meter, wait two hours, read it again. Any movement with everything off means water is going somewhere.

Will Austin Water adjust a bill caused by a leak?

A leak adjustment exists for repaired leaks with proof. There is also a narrower non-leak path. The official review decides the credit; the adjustment-request page covers both.
