Key takeaways
- 811 is the national call-before-you-dig number
- It gets public utilities marked, usually for free
- Private lines such as your sewer lateral are often not marked
- A private locate fills the gap
What 811 does
Call 811 a few days before digging. Utility companies mark the locations of their buried lines, such as gas, electric and communications, with colored paint and flags.
It is the law in most places and it prevents serious accidents.
What it does not cover
Most one-call services mark utilities owned by the utility companies, up to the meter or the property line. Private lines, such as your sewer lateral from the house to the main, a private water line or irrigation, are generally not marked.
Ask 811 what they cover in your area.
Why private lines get hit
Fence installers, pool builders and landscapers dig after the public marks go up and still strike an unmarked sewer pipe. The repair is the owner’s responsibility.
It is a surprisingly common and costly mistake.
Do both
Call 811 for public utilities and hire a private locator for your sewer. Give the marks to your contractor, hand-dig near them and keep a photo of the markings.
It takes little time and avoids a big bill.
Quick answers
Does 811 cost money?
The call and the public marking are generally free. A private locate by a company is a paid service.
How far ahead should I call?
Check your state’s rule. A few business days before digging is common.
