Pipeline safety: call 811 before you dig
Fencing, landscaping, pools and other projects requiring digging can cause damage to pipeline infrastructure if not properly planned. By law, calling 811 is the responsibility of the excavator, and excavators are liable for resulting damages.
Calling 811 is free.
