Hydrovac for Electric Utility Construction & Maintenance
Explore how hydrovac excavation serves the electric utilities sector.
Electric utilities use hydrovac excavation extensively for both overhead and underground power infrastructure projects. Working around energized underground cables, conduits, and grounding systems requires the utmost precision to prevent electrocution hazards, service outages, and equipment damage.
Non-destructive excavation is critical when exposing underground power cables for repair, installing new conduit runs for distribution expansion, and excavating around transformer pads and switchgear foundations. A single cable strike on a high-voltage underground feeder can cause arc flash incidents, extended outages affecting thousands of customers, and millions of dollars in damage.
Hydrovac technology enables electric utility crews and their contractors to safely expose underground infrastructure at any depth, in any soil condition, while maintaining safe clearance distances from energized components. This capability is especially important during storm damage restoration when rapid, safe access to underground systems is essential.
Common Applications
- Underground cable exposure and repair access
- Transformer pad and switchgear foundation excavation
- Conduit installation for distribution expansion
- Grounding system installation and maintenance
- Pole foundation excavation in congested areas
- Streetlight base installation
- Storm damage restoration excavation
- Substation underground work
Typical Projects
Underground Cable Replacement
Exposing aging underground power cables for replacement while protecting adjacent gas, water, and telecom utilities. Hydrovac prevents arc flash hazards from mechanical contact with energized conductors.
Transformer Pad Installation
Excavating for new pad-mounted transformer foundations in residential subdivisions and commercial developments where underground utilities are densely packed.
Storm Restoration
Rapid, safe excavation to expose damaged underground systems after severe weather events. Speed is critical for restoring power, but safety around potentially energized components cannot be compromised.
Grid Modernization
Installing new underground conduit and equipment foundations for smart grid infrastructure, including automated switches, sensors, and communication systems alongside existing power infrastructure.
Regulatory Considerations
- ●OSHA electrical safety standards (29 CFR 1926 Subpart K)
- ●NESC (National Electrical Safety Code) clearance requirements
- ●State Public Utility Commission regulations
- ●NERC reliability standards for bulk electric systems
- ●Arc flash hazard analysis requirements
- ●Minimum approach distances for energized conductors
Equipment Recommendations
- Dielectric (non-conductive) wands and nozzle assemblies
- Grounded hydrovac trucks with proper bonding
- Low-pressure water capability for work near cables
- Extended boom reach for maintaining safe distances from overhead lines
