Underground Damage Prevention's Common Hazards
Oil & Gas
Natural gas heats our buildings, fires our stoves and fireplaces and generates electricity.
Water & Sewer
Water and sewer lines seem like the least problematic of all the underground utilities.
Electrical
Overhead electric lines are easy to spot and avoid. Underground lines are buried and not.
Telecom
Telecom refers to any communication services, including telephone, internet and cable TV.
