Does 811 locate private sewer lines?
Usually not. 811 is important before digging, but it generally marks public utilities, not private sewer laterals or privately owned buried lines. That is where a private locate can matter.
What 811 typically covers
811 is a “call before you dig” service that alerts utility operators so they can mark public underground lines. This often includes:
- Public gas lines
- Public electric
- Telecommunications
- Public water mains
- Municipal sewer mains
What 811 typically does NOT mark
In many municipalities, 811 does not mark private utilities on your property, such as:
- Private sewer laterals (house to street)
- Privately owned water lines
- Private conduit / buried wiring (often property-owned)
- Septic system components
Why private sewer laterals are a big deal
If you strike a private sewer lateral, you may be responsible for the repair and restoration costs. A private locate helps reduce risk before projects like:
- Foundation repair
- Fence or deck footings
- Tree planting
- Landscaping and drainage trenches
- Driveway / patio work
What to do next
Start with 811 for public markings, then consider a private locate for private utilities. Learn exactly what we do on our Foundation Piping & Private Utility Locates service page.
