Safe, precise digging for complex sites
Bunney’s Inc. delivers these services statewide for industrial, commercial, and municipal work. Vacuum excavation trucks (a.k.a. hydrovac trucks) pair high-pressure water or air with a powerful vacuum to expose buried utilities without damage. The result is fast, non-destructive excavation that keeps sites cleaner, shortens outages, and reduces restoration costs—ideal for congested corridors, plant sites, and sensitive rights-of-way.

What is vacuum excavation?
Vacuum (hydrovac) excavation uses a controlled stream of pressurized water (or air) to loosen soil while a high-powered vacuum removes the slurry to a debris tank. Typical use cases:
-
Non-destructive digging method that uses pressurized water or air plus suction to excavate with precision.
-
Soil is loosened and vacuumed into an onboard debris tank, keeping the work zone clean and controlled.
-
Greatly reduces utility-strike risk, ideal within tolerance zones and congested corridors.
-
Minimizes surface disruption to pavement, hardscape, and landscaping—less restoration afterward.
-
Supports safety and compliance with 811 damage-prevention and utility-owner standards.
-
Utility location & daylighting: visually confirm exact depth and alignment before mechanical digging.
-
Potholing and test holes for quick, targeted subsurface checks.
-
Slot trenching for conduit and small-diameter pipe with narrow, accurate cuts.
-
Trenching near critical infrastructure (gas, fiber, water, power) where precision is essential.
-
Debris, mud, and ballast removal from vaults, pits, and sumps for maintenance and cleanouts.
Compared with mechanical digging, soft-dig methods minimize utility strikes, surface disruption, and rework, while supporting compliance with damage-prevention laws.
Why Arizona contractors prefer vacuum excavation
-
Lower utility-damage risk – Precise daylighting reduces strikes and service interruptions.
-
Minimal surface disturbance – Protects pavement, hardscape, and landscaping.
-
Cleaner, tighter work zones – Spoils are contained in the truck for proper disposal.
-
Faster permitting & inspections – Visual verification supports accurate as-builts.
-
Safer crews & sites – Less hand digging around energized or pressurized lines.
-
Better in variable soils – Handles caliche, sands, and mixed backfill common across Arizona.
How to choose a reliable vacuum excavation partner
-
Relevant experience – Industrial/commercial focus and documented utility-protection practices.
-
Fleet capability – Modern hydrovac trucks (water & air), heated options, long-reach booms.
-
Safety record – Operator training, JSAs, confined-space and traffic-control programs.
-
QA documentation – Photos, depths, utility IDs, spoil manifests, and daily reports.
-
Dispatch & coverage – Rapid mobilization and statewide service for critical schedules.

Where vacuum excavation fits your workflow
-
Before you dig: 811 locates mark the area; hydrovac daylighting pinpoints exact depth and alignment.
-
During construction: Slot trenching and tie-ins near live utilities reduce risk and downtime.
-
Afterward: Debris and mud removal keeps vaults, pits, and job sites clean and compliant.

FAQs
What’s the difference between water and air excavation?
Water (hydrovac) cuts tougher soils faster; air (air-vac) keeps spoils dry for reuse and is preferred where fluid isn’t allowed. Bunney’s Inc. advises based on soil, utility risk, and restoration needs.
Can vacuum excavation work in hard caliche or rocky soils?
Yes. Water excavation with proper nozzles and flow rates handles caliche and mixed backfill effectively; production rates are planned accordingly.
How close can you dig to marked utilities?
We follow tolerance-zone rules and daylight to visually confirm exact location before any mechanical excavation proceeds.
Is traffic control provided?
For work in active corridors, Bunney’s Inc. can provide MUTCD-compliant traffic control plans and setups as required by the jurisdiction.
What happens to the spoils?
Slurry is contained in the truck. We can dispose at approved facilities or manage on-site handling to meet environmental and owner requirements.
Do you operate statewide?
Yes—based in Phoenix and serving industrial, commercial, and municipal clients across Arizona.
How do you price hydrovac work?
Typical models include hourly (truck + crew), day rates, or unit pricing for potholes/linear feet. We scope access, production, disposal, and traffic control up front for a clear quote.
Can you work at plants and energized sites?
Yes. Our teams follow site-specific orientations, LOTO interfaces, and utility owner procedures, with documentation for audits.
