ComEd responded immediately to de-energize the damaged line, and worked to isolate the area so that some customers could get their electric power restored. Customers as far away as Lexus of Arlington on Dundee Road and Wilke Road experienced a power outage for about 30 minutes.

A hydrovac truck and a horizontal boring machine were located on the scene. Utility locations were marked with flags and spray paint.

Hydrovac excavation is designated to be a non-destructive method of excavation that uses pressurized water and a powerful vacuum from a large truck to quickly and safely expose buried pipes and cables. The vacuum truck is a tanker truck with a heavy-duty vacuum connected. Using a pneumatic process, the vacuum can load solids, liquids, mud, sludge or slurry into the tank on the truck through suction lines that are usually about 6-8″ in diameter.

Vacuum trucks can also be used to expose underground utilities with the hope of eliminating the chance of damage to the utilities. The ground is jetted with a high-pressure water stream and the vacuum truck sucks up the water and mud, which exposes the buried utility while minimizing the chance of damage. The risk of damage is much less than the damage that might occur when a backhoe is used.
