Hydrovac Excavation
The $500K-a-truck business that digs up America's buried infrastructure
Bottom line
Worth studying, but do not buy without strong local proof.
Hydrovac excavation uses pressurized water and a vacuum system to safely expose underground utilities without risk of hitting gas lines, fiber, or electrical conduits. Every construction project near utilities is legally required to use safe digging methods — and hydrovac is the gold standard. A well-run truck generates $300K–$500K/year, and a 3-truck operation can generate $1M+ with one operator-manager. The global market is growing at 5%+ CAGR as infrastructure spending accelerates.
How It Works
Contractors, utilities, and municipalities hire hydrovac companies to expose underground lines before digging. Jobs are charged by the hour ($250–$500/hr) or by the project. Trucks can run 2,000+ billable hours per year in active markets. Government infrastructure contracts provide recurring, predictable revenue.

Hydrovac Excavation
Revenue drivers
- • Billable truck hours, hourly rate, daily minimums, mobilization, and disposal fees
- • Customer mix: utility daylighting, telecom, municipal, industrial, pipeline, and construction work
- • Truck utilization after weather, locate delays, dump runs, refill time, and maintenance
- • Crew skill around utilities, frozen ground, confined sites, and safety documentation
- • Route/yard proximity to water fill points and approved slurry disposal
Key risks
- • A single truck combines high debt service with one-point failure risk
- • Locate delays and dump runs can turn a quoted day into low utilization
- • Bad operators can damage the utility the method is supposed to protect
- • Disposal rules and slurry distance quietly eat margin
- • Customer concentration in one utility or contractor creates tender/renewal risk
What you need to believe
- The truck earns paid hours often enough to cover high fixed cost
- Customers buy damage-prevention reliability, not commodity excavation
- Mobilization, water, and disposal are priced instead of absorbed
- Drivers and helpers can operate safely without the seller on site
- Maintenance records make downtime underwritable
Unit economics
How one unit makes money
Modeled per one full-size hydrovac truck with a two-person crew. Every line shows its arithmetic — rebuild any number yourself.
Revenue build-up
| Line | Low | Base | High |
|---|---|---|---|
| Billable hydrovac hours960-2,400 billable hours/year × $250-$500/hour; base is 1,600 hours × $375/hour | $240K | $600K | $1.2M |
| Mobilization, water, disposal, daily minimums160-300 job-days/year × $375-$1,000 in non-dig charges when quoted separately | $60K | $100K | $300K |
Where it goes — cost structure
- Crew labor and overtime22–34%
Most jobs need 2-3 operators; the truck is idle without qualified people.
- Fuel, water, disposal, dump/refill time10–20%
The invoice may say excavation, but slurry logistics are often the margin leak.
- Maintenance, wear parts, tires, hoses, pumps, boilers8–16%
Frozen ground and clay make revenue, but they also punish pumps, boilers, and hoses.
- Truck financing/replacement reserve8–15%
A full-size hydrovac is a high-ticket asset; under-reserving makes SDE look heroic.
- Insurance, permits, yard, dispatch, admin6–11%
Utility and municipal customers expect safety paperwork, not a guy with a hose.
What actually swings the deal
- Billable hours
100 additional billable hours at $375/hour = +$37.5K revenue before crew and variable costs.
- Hourly rate
$25/hour across 1,600 billable hours = +$40K revenue if utilization holds.
- Disposal/refill leakage
One unbilled hour per job-day across 200 days at $375/hour is $75K of invisible revenue leakage.
- Truck downtime
Five missed 8-hour days at $375/hour = ~$15K revenue, before the customer-reliability damage.
Benchmarks to memorize
One truck at 1,800-2,000 billable hours is already busy after weather, maintenance, dump/refill time, and dispatch friction. Above ~$900K-$1M revenue, growth usually means a second truck or unusually premium industrial work.
Market analysis
Who owns these & where demand comes from
Hydrovac is a capital-heavy specialty inside excavation and utility maintenance. It is not a generic digging business: buyers are paying for non-destructive daylighting around infrastructure where one utility strike costs more than the invoice.
Tailwinds
- ↗ CGA damage data keeps pressure on owners and contractors to prevent strikes
- ↗ More underground utility work increases daylighting and potholing demand
- ↗ Customers increasingly outsource specialized equipment instead of owning idle trucks
Headwinds
- ↘ Truck financing and maintenance make low utilization dangerous
- ↘ Large providers can win multi-region contracts
- ↘ Weather, dump sites, water access, and locate delays cap usable hours
Demand drivers
- Aging underground utility infrastructure and telecom/fiber buildouts require safe exposure work
- 811/damage-prevention pressure pushes contractors toward non-mechanical excavation near buried assets
- Frozen ground, congested corridors, and urban sites favor vacuum excavation over backhoes
- Municipal, utility, industrial, and pipeline customers value documentation and safety records
Regulation
Moderate to high. Operators manage excavation safety, traffic control, confined/site rules, CDL/driver compliance, 811 locate processes, disposal rules for slurry, customer safety requirements, and OSHA trenching/excavation expectations where pits are opened.
Who you bid against
Badger-style fleets, site-prep contractors, utility contractors, municipal vendors, and searchers attracted to equipment-backed SBA loans. Existing contractors with customer flow can justify a truck faster than a stand-alone buyer.
Competitive advantage
What protects the good ones
- strongRoute/site density
Trucks earn only when near paid work, water, and disposal; dense utility corridors beat scattered construction calls.
- strongSafety/compliance reputation
The job exists to avoid utility strikes. One bad incident can remove the vendor from approved lists.
- moderateEquipment ownership and uptime
The asset is expensive and financeable, but maintenance records and uptime create real customer confidence.
- moderateContracts/recurring mandates
Utilities, municipalities, and industrial sites need repeat daylighting and expose work. Recurrence smooths a capital-heavy model.
Who wins — and who loses
The winner runs hydrovac like an airline: utilization, dispatch, maintenance, safety record, and non-billable time are managed daily. The loser buys a beautiful truck, wins low-bid construction work, donates mobilization and dump time, and learns that a $700K asset can still be a bad job if it only bills four clean hours a day.
How this niche degrades
- ↘ Large fleets like Badger can pressure enterprise accounts and absorb national safety requirements
- ↘ Locate delays and infrastructure-work cycles create utilization volatility
- ↘ Fuel, labor, disposal, and financing costs move faster than stale hourly rates
- ↘ A utility strike or serious safety claim can destroy approved-vendor status overnight
More consolidated than most local services because the equipment is expensive and national customers value safety systems. Small operators still win dense local work, emergency responsiveness, and relationships with municipalities, contractors, and utilities.

Valuation framework
How these actually get priced
Valued on SDE, but the buyer should cross-check against truck value, debt service, utilization, maintenance reserve, and customer recurrence. The in-repo SBA proxy shows site-prep transactions can be million-dollar deals; that only helps a small hydrovac buyer if revenue per truck-day and maintenance history are clean.
What moves the multiple
- ▲ PremiumRecurring utility/municipal/industrial accounts
They reduce utilization risk and support the capital base.
- ▲ PremiumDocumented uptime and safety record
The customer is buying risk reduction; maintenance logs and incident history are deal value.
- ▼ DiscountOne-truck concentration
A single breakdown stops revenue while debt service keeps running.
- ▼ DiscountUnbilled disposal/mobilization time
Quoted revenue can overstate SDE if dump/refill and travel are absorbed.
Worked example
$700K revenue × 28% margin = ~$196K SDE. At 2.5x-4.0x, indicated value is roughly $490K-$784K. The high end requires repeat accounts, clean truck records, priced disposal/mobilization, and low downtime; a one-truck seller with vague utilization should trade closer to equipment value plus customer list.
Common buyer mistakes
- ✕ Paying for the truck and forgetting that utilization is the business
- ✕ Ignoring dump/refill, water, and mobilization leakage
- ✕ Normalizing seller labor without replacing CDL/operator capability
- ✕ Treating construction backlog as recurring utility demand

Due diligence checklist
Before you sign anything
- 01
Export 24 months by job-day: billable hours, rate, mobilization, water/dump time, disposal fees, crew hours, truck, customer, and gross margin.
This verifies billable-hour, rate, and disposal/refill sensitivities.
Red flagThe seller tracks invoices but not billable versus non-billable truck time. - 02
Calculate revenue per truck-day and utilization by month, then tie downtime to maintenance records.
A high-capex truck needs predictable earning days.
Red flagRevenue depends on a few heroic months or downtime is explained verbally. - 03
Inspect truck age, hours, pump/boiler condition, hose inventory, maintenance logs, debt terms, warranty, and replacement quote.
Equipment reserve and downtime attack the SDE bridge.
Red flagMajor components are near replacement and no reserve was charged to earnings. - 04
Verify approved-vendor status, safety record, utility strikes, claims, insurance certificates, and customer audit results.
Safety/compliance reputation is the moat.
Red flagAny recent strike, claim, or suspended vendor status not disclosed upfront. - 05
Map water fill points, disposal sites, fees, and average round-trip distance for top customers.
Disposal/refill leakage can erase rate increases.
Red flagMost jobs require long dump runs that are not separately billed.
Pros
- +Mandatory compliance work — contractors cannot legally skip it
- +Infrastructure spending tailwind drives long-term demand
- +High hourly rates with government and utility contracts
- +Competitive barrier: equipment cost keeps casual entrants out
Cons
- -Truck cost of $400K–$700K new creates capital requirement
- -Maintenance-intensive equipment with high downtime risk
- -Requires CDL drivers and specialized operator training
Best For
Operators with civil construction experience or existing relationships with utilities and contractors
Operating Costs
Operating costs run $100K–$200K per truck per year: fuel, maintenance, insurance, CDL driver wages, and disposal fees for excavated material.
