If you are budgeting a job that needs hydrovac excavation, also called hydro excavation or vacuum excavation, the first question is usually what it costs. The honest answer is that most hydrovac work is priced by the hour, and the total depends on how long the truck is on your site, how far it travels, and how much material it hauls away.
This guide breaks down published hydrovac pricing, the pricing models you will see on quotes, and the Florida specific factors that affect cost in Tampa, St. Petersburg, Clearwater, Brandon, and the rest of the Tampa Bay area.
Hydrovac cost at a glance
| Typical hourly rate, truck and operator | About $300 to $475 per hour in published U.S. pricing |
|---|---|
| Flat rate per pothole | Some contractors quote around $500 per pothole, subject to job minimums |
| Full day | Flat day rates of around $5,000 have been published for full days of trenching |
| Usually billed separately | Disposal, travel or mobilization, traffic control, and surface cutting |
| Biggest cost drivers | Hours on site, depth, soil, number of holes, and distance to disposal |
Ranges come from the published sources listed at the end of this guide. Every job is quoted individually; use these numbers for budgeting, not as a bid.
How hydrovac pricing works
A hydrovac truck is an expensive piece of equipment. New trucks run roughly $350,000 to $600,000, and every hour on a job includes the truck, fuel, water, maintenance, and a trained operator. That is why hydrovac work is almost always priced by time rather than by the cubic yard. You will typically see one of four pricing models on a quote:
Hourly rate
The most common model. You pay for the hours the truck and crew are working on your project, often from the time they leave the yard until they return or finish disposal. Published hourly rates for outsourced hydro excavation, which include the operator, overhead, and profit, range from about $375 to $475 per hour in a 2026 industry cost guide, while one hydrovac contractor publishes a range of $300 to $400 per hour.
Job minimum
Because mobilizing a truck costs the same whether the job takes one hour or six, many operators set a minimum charge. If you only need one or two quick test holes, ask what the minimum is before you book. Grouping several small tasks into one visit is usually cheaper than scheduling separate trips.
Per pothole pricing
For potholing and utility verification, some contractors quote a flat rate per hole. One published example is $500 per pothole, subject to job minimums. Per hole pricing is easy to budget, but it usually assumes standard depth and soil, so very deep holes or holes through concrete may be priced differently.
Day rate or standby
For long jobs such as slot trenching, line exposure for a repair crew, or support for a directional drilling crew, a day rate or standby rate can make more sense than counting hours. One contractor publishes around $5,000 for a full day of trenching. Standby pricing keeps the truck on site and ready while your crew works.
What makes a hydrovac job cost more or less
Two jobs with the same number of holes can be priced very differently. These are the factors that move the number:
- Depth. Deeper holes take more time and produce more spoil to haul away.
- Soil. Loose sand cuts quickly. Clay, compacted fill, and hardpan take longer to break up, and rock may need other tools.
- Number of holes or length of trench. More holes or more feet of slot trench means more time on site.
- Surface. Holes through asphalt, concrete, or pavers need cutting or coring first, which adds time and equipment.
- Access. If the truck cannot park close to the dig, the crew runs longer hose, which slows production.
- Water and disposal. The truck needs water to dig and a legal place to dump the slurry. Equipment maker Vermeer notes that disposal costs are rising as fewer facilities accept material, and that a round trip to a disposal site can take from 30 minutes to two hours depending on traffic.
- Traffic control. Work in a road or right of way may require lane closures or flaggers, which are often billed separately.
- Timing. Nights, weekends, and emergency callouts are often billed at a higher rate than scheduled weekday work.
- Documentation. Depth logs, photos, and GPS data for engineering or SUE work take extra time on each hole.
Florida factors that affect cost in Tampa Bay
Ground conditions in Tampa Bay work both for and against your budget:
- Sandy soil digs fast. Much of the region is fine sand, which a hydrovac breaks up and removes quickly compared with heavy clay.
- The water table is shallow. In many areas groundwater sits close to the surface. The vacuum removes water as it digs, but wet holes produce more liquid to haul, which can mean more disposal loads.
- Limestone and old fill show up. Pockets of limestone and decades of layered fill in older neighborhoods can slow a job that looked simple on paper.
- Summer storms. During the June to September rainy season, afternoon lightning can pause work, and a hole that fills with rain may need to be cleaned out again.
- Traffic and travel. Downtown Tampa, the Gandy and Howard Frankland corridors, and Pinellas beach areas can add travel time between the yard, your site, and the disposal facility.
Example: estimating a potholing job
A simple way to estimate is: billable hours × hourly rate + travel + disposal + extras. For example, if a potholing job takes 6 billable hours at $400 per hour, the truck time comes to $2,400. Disposal, travel, surface coring, or traffic control would be added on top of that.
To estimate spoil, Vermeer's example is useful: a 1 foot wide hole dug 5 feet deep removes about 0.15 cubic yards of soil, and with water mixed in, each hole produces roughly 0.3 cubic yards of slurry. Ten holes make about 3 cubic yards, and an 800 gallon tank holds the spoil from about 13 holes before it must be emptied. Larger trucks hold more.
Is hydrovac worth the cost compared with a backhoe?
By the hour, a hydrovac costs more than a backhoe. But the hourly rate is rarely the number that matters. The Common Ground Alliance estimated that damage to underground utilities from excavation cost the United States about $30 billion in 2019. A single strike on a gas service, a fiber trunk, or a water main can bring repair bills, crew downtime, fines, and safety risk that dwarf a day of hydrovac time.
Hydrovac also saves money in less obvious ways:
- Smaller holes mean less backfill and less pavement or landscape restoration.
- No spoil pile is left on site, so there is no separate cleanup or hauling.
- Florida law calls for careful methods such as hand digging, potholing, or vacuum excavation inside the 24 inch tolerance zone around marked lines. Read more in our guide to Florida 811 rules before you dig.
How to get an accurate hydrovac quote fast
The more detail you give up front, the tighter and faster the quote. Include:
- The jobsite address or nearest intersection
- The service you need, such as potholing and daylighting, slot trenching, or debris and spoil removal
- The number of holes or the length of trench, and the target depth
- The surface at each spot: grass, asphalt, concrete, pavers, or brick
- The utilities involved and your Sunshine 811 ticket number, if you have one
- Access notes: gates, distance from parking, overhead lines, and traffic
- When you need the work done, and whether you need photos or depth records

Frequently asked questions
How much does hydrovac excavation cost per hour?
Published rates for hydrovac service with a truck and operator generally run about $300 to $475 per hour in the U.S. Disposal, travel, traffic control, and surface cutting are often billed separately.
How much does potholing cost?
Some contractors price potholing per hole, with published examples around $500 per pothole subject to job minimums. Others bill potholing by the hour. Deep holes or holes through concrete usually cost more.
Is there a minimum charge for hydrovac service?
Many hydrovac operators set a job minimum because mobilizing the truck costs the same for a short job as a long one. Ask about the minimum when you request a quote, and group small tasks into one visit when you can.
Why is disposal charged separately?
The slurry a hydrovac removes has to be hauled to a facility that accepts it. Disposal fees and travel time vary by location and volume, so they are usually listed as their own line item.
Is hydrovac cheaper than a backhoe?
Per hour, no. Overall, it often is, because hydrovac avoids utility strikes and leaves smaller holes that need less restoration. Excavation damage to U.S. utilities was estimated at about $30 billion in 2019.
What affects hydrovac cost in Tampa Bay?
Depth, soil, the number of holes, surface type, access, traffic control, travel and disposal distance, and timing. Tampa Bay sand digs quickly, but a shallow water table and summer storms can add disposal loads and delays.
