If your work involves excavation, when was the last time you or your company was liable for damage to unknown underground utilities?  There is excavation technology available that will reduce liability and eliminate the possibility of damage to foreign underground utilities and structures.

Hydro excavation, although not a new technology, has with in the past few years been more widely used by excavations and owners of underground utilities.  It is being used to positively locate and identify existing underground utilities prior to using mechanical means and equipment in the area.  This allows the use of mechanical digging to proceed in a faster and safer manner without the risk of striking unknown underground installations.  It also can be used as a means of primary excavations without danger of damaging unmarked utilities.

What is hydro excavation?  It is a safe and non-destructive digging method using pressurized water (hydro) and a vacuum system to dig.  The key components of hydro excavation are; minimal water usage to break up the dirt, and powerful air movement to move the chunks of dirt and rock into the debris tank.  When looking for the optimum process, you want to minimize the water used to dig, and maximize the air movement.  Using excess amounts of water to dig creates a three-fold problem.  First you are moving more water than dirt, and second the excess water is taking up valuable volume in the debris tank, and third, the water slurry created has to be disposed of.  These three factors adversely affect production.  The perfect combination of water and suction produces a practically dry spoil that can be handled easily and effectively.

This truck is self contained and works as three separate entities in one:  a water truck, a pressure truck and a vacuum truck.  Water from the truck’s 1300 gallon stainless steel tank is pressurized at pressures up to 2500 psi and delivered through a unique hand held wand used to penetrate the soil.  The resulting sludge (composed of soil and some water) is then vacuumed into the debris hose by a powerful vacuum hose system (3,000 CFM) or 173 mph material velocity, which then allows the debris to be collected in the 10 cubic yard debris tank.  The truck also has a debris transfer system (blow off) as well as the standard full opening back door.  This blow off allows one to blow off into a different receptacle rather than having to drive away to dump.

The debris can then be dumped for storage on site, removed from the site to make way for new or replacement fill if required or transported for environmentally safe disposal.  The hydro excavation process is very versatile depending on the type soil and depth of excavation.  It can be used for potholing, locating and positively identifying any type underground utilities, repairing pipelines, communications and electrical cables, slot trenching, directional drilling, signs and pole installations, and excavating in congested areas up to 400 feet from streets or drives.  The unit also has a heater for excavations in frozen soil.

The process provides positive liability control when compared to mechanical excavation and qualifies in some situations where hand digging is required by law.

Whether used to enhance the use of mechanical excavation for safety and improved productivity or as a primary means of excavation, it can be cost effective as well as reducing risk of personal injury, property damage and negative publicity when damaging unknown and unmarked underground utilities.
