What to do if…
water starts bubbling up in the garden or driveway and you suspect a buried pipe leak

Short answer

Treat bubbling water as both a leak and a ground-collapse hazard: keep people/vehicles away, shut off your home’s water at the main if you can, then report it to your local water utility (and your landlord/property manager if you rent).

Do not do these things

  • Don’t start digging to “find the break” (you can hit buried utilities and worsen the collapse).
  • Don’t drive over the area or let kids/pets play there (voids can form under the surface).
  • Don’t assume it’s safe just because the water looks “clean.”
  • Don’t delay contacting the utility if it’s near the street/sidewalk or flowing fast.
  • Don’t dig until you’ve contacted 811 and utility markings are completed.

What to do now

  1. Create a no-go zone. Keep everyone and everything off the bubbling/wet area (including vehicles). If it’s a driveway, block it and avoid that section.
  2. Shut off water to limit damage (if safe).
    • Turn off your home’s main shutoff valve (commonly where the line enters the house, basement/crawlspace, garage, or near the meter).
    • If water is approaching electrical panels/outlets or powered equipment and you can’t isolate safely, increase distance and move to step 5.
  3. Quick “is it still feeding?” check (no digging).
    • With all indoor water off, see if the water meter still shows flow (many meters have a small flow indicator). Continuous movement suggests an active leak.
  4. Report it to the right place based on where it is.
    • In/near the street, sidewalk, alley, or public right-of-way: report to your water utility/public works right away.
      • If your city has 311, it may route non-life-threatening street leak reports; if not, use the utility’s published emergency number or online “report a problem” tool.
    • Clearly on your property: you may need a licensed plumber, but it can still be smart to notify the utility if you’re unsure or if it’s near the meter/curb area.
    • If you rent: notify your landlord/property manager immediately.
  5. Call 911 only for immediate danger. Examples: rapid ground collapse, a street/sidewalk becoming unsafe to the public, water creating a serious electrical hazard, or a traffic hazard that can’t be controlled.
  6. Document what you can safely. Take photos/video (wide + close-up) showing:
    • the bubbling point and surrounding wet ground,
    • any cracking/sinking,
    • proximity to the home, driveway edge, sidewalk, or curb.
  7. If anyone may dig later, start with 811. Submit a free 811 locate request before any excavation so buried utilities can be marked.

What can wait

  • You do not need to diagnose whether it’s “utility side vs customer side” before you report — reporting first is appropriate.
  • You do not need to dig test holes or trace the line today.
  • You do not need to sort repair bids/insurance decisions until the leak is controlled and responsibility is clearer.

Important reassurance

This feels urgent because it can change quickly — that instinct is valid. Keeping the area clear, stopping the water feed if you can, and getting the utility/landlord involved are the right early moves.

Scope note

This guide covers first steps only. After the immediate risk is controlled, next steps may include utility assessment, leak location, repair scheduling, and documentation for your insurer or landlord.

Important note

This is general information, not professional plumbing, utility, or safety advice. If you see rapid sinking, major roadway/sidewalk damage, or a serious electrical hazard, prioritise distance and emergency services.
