What does 811 mean?

Answer 1

Well, as a number, 811 is eight hundred and eleven.

For Professional excavators and home DIYers, "811" is the number to call to have underground gas pipes, sewer pipes, and water pipes as well as cables enclosed in pipes to be located from the ground surface and marked before anyone begins a digging job. If a home owner or professional digs without this knowledge, they could puncture a pipe or cut into an underground cable. This could have widespread damage, and cost many thousands of dollars to fix the puncture and to pay fines.
