Safer, cleaner excavation for utility-dense job sites
At Bunney’s Inc., vacuum (hydrovac) excavation uses high-pressure water to loosen soil while a powerful vacuum removes the spoil—delivering precise, non-destructive digging that protects buried utilities, shortens outages, and keeps sites cleaner—ideal for urban corridors, plant sites, and sensitive rights-of-way across Arizona.

Minimal surface disruption: Fewer pavement cuts, cleaner edges, and simpler restoration than mechanical digging.
-
Statewide reach: Based in Phoenix with mobilization across the state for single callouts or multi-month programs.
What a hydrovac company does
A hydrovac provider delivers non-destructive excavation services such as:
-
Daylighting/potholing: Verify line depth and location before crossing or boring.
-
Slot trenching: Narrow, accurate trenches for conduit and small-diameter pipe.
-
Utility conflict checks: Expose crossings at intervals along new alignments.
-
Valve boxes & structures: Cleanouts around appurtenances without damage.
-
Footing & pier holes: Form-ready holes with clean walls and accurate dims.
-
Spill & debris removal: Vacuum recovery of slurry, ballast, or material from vaults and sumps.
Where hydrovac shines in Arizona
-
Utility-dense corridors: Reduce strike risk around gas, fiber, reclaimed water, and electrical duct banks.
-
Plant & terminal work: Confined areas, live facilities, and strict housekeeping requirements.
-
Arid soils & caliche: Water loosens hard lenses that challenge mechanical buckets.
-
Monsoon season: Cleaner trench control and easier erosion management after storms.
Our process (fast, compliant, documented)
-
Pre-plan & 811 coordination: Review locates, drawings, permits, and traffic control.
-
JHA & site setup: Barricades, grounding where required, and safe spoil management.
-
Hydro cutting & vacuuming: Controlled water jetting, debris conveyed to sealed tank.
-
Exposure verification: Measure depth/offsets, capture photos, and mark as-built details.
-
Backfill or protection: Replace select fill or install temporary protection per spec.
-
Disposal & reporting: Manifest slurry to approved facilities; provide daily logs and closeout photos.

Hydrovac vs. mechanical digging
| Task | Hydrovac | Mechanical |
|---|---|---|
| Utility exposure | Non-destructive, precise | Higher strike risk |
| Restoration | Minimal | Often larger patches |
| Production in utility-dense areas | Consistent | Slower due to hand-digging |
| Documentation | Photos/measurements standard | Varies by crew |

FAQs
What is hydrovac excavation?
A non-destructive digging method that uses pressurized water to loosen soil and a vacuum to remove the slurry, exposing utilities or creating trenches with minimal damage.
When should I choose hydrovac over a backhoe?
Anytime you’re near known/unknown utilities, in tight corridors, working inside live facilities, or when clean, narrow excavations reduce restoration costs.
How deep can you safely expose lines?
Depth depends on soil, groundwater, and access, but typical daylighting ranges from 2–15 feet. We’ll review plans and choose the right setup for deeper targets.
What happens to the slurry?
Material is vacuumed into a sealed debris tank and hauled to an approved disposal site. We provide manifests and keep the work zone clean.
Do you handle permits and 811?
We coordinate with your team on required notifications, traffic control, and permits. Blue-stake/811 must be active before we dig.
Do you work statewide?
Yes. We mobilize from Phoenix to projects across Arizona for single-day tasks or multi-week programs.
Do you take residential jobs?
No. We focus exclusively on industrial, commercial, and municipal work.
How does pricing work?
Rates reflect production goals, access, disposal distance, and traffic control needs. You’ll receive a transparent, line-item quote.
