Symptom guide
Sinkhole Or Ground Depression
Ground movement near a line can indicate a washout. Treat it carefully.
Small depressions near a service route can mean soil is being washed away by a leak. It deserves measurement and investigation rather than filling.
What to check yourself
- Mark and measure the depression
- Keep people and vehicles away from the area
- Check the meter for continuous movement
Likely causes
- A service or drain line washout
- A failed culvert or storm connection
- Settlement unrelated to water, which an engineer should assess
What the investigation does
- Locate the line and test for loss
- Document the situation for the authority
- Coordinate excavation only after locating
Methods often used
Quick answers
What should I do first about this?
Locate the line and test for loss
Can this be fixed without opening everything?
In most cases the investigation narrows the target before any finish is opened. Small access points are sometimes needed to confirm a finding, and that is discussed before anything is opened.
