Vac Truck Services That Drive Critical Operations
A Technical Look at the Vac Truck Workhorses of Oil & Gas Facility Support
Introduction: The Backbone of Field Operations
In the industrial services world, vac trucks aren’t just for waste—they’re the backbone of field support. From dewatering tanks and flushing sumps to supporting confined space entry and removing chemical residue, these rigs are central to keeping facilities safe, clean, and running.
At Solution Services, vac truck operations are a core division, not a bolt-on offering. Our fleet and operators are embedded in every major scope we execute—whether it’s a crude tank turnaround, an exchanger pull, or a vapor phase chemical cleaning. We deploy them strategically, operate them expertly, and integrate them seamlessly into broader workflows.

What Is a Vac Truck—and What Can It Actually Do?
A vac truck uses high-powered suction to remove liquids, sludge, solids, and waste streams from tanks, pits, sumps, vessels, and more. But their real value lies in how and where they’re applied.
Types of Units in Our Fleet
🟢 Combo Vac Units
These are the Swiss Army knives of the fleet. Our combo units provide powerful suction alongside integrated high-pressure water jetting. Each unit includes a Hotsy burner, enabling hot water washing for degreasing, wax breakdown, or chemical residue removal. This makes them ideal for sump cleaning, confined space prep, chemical rinse recovery, and even light-duty surface cleaning—all in one truck.
🟢 Semi Vacs
Built for high-volume hauling, our semi vacs are deployed when large volumes of waste need to be transferred offsite. They often run in rotation with combo units during major scopes, ensuring uninterrupted progress on site. These units are key to keeping projects moving—especially during shutdowns and tank cleaning where high output volumes are expected.
🟢 Hydrovacs
For subsurface work—daylighting, excavation near lines, and utility exposure—our hydrovac units use high-pressure water and vacuum to safely cut through soil without risking strikes. These units are used heavily in pre-job tie-in prep or mechanical maintenance scopes.

Technical Applications for a Vac Truck in Oil & Gas Facilities
Vac trucks are instrumental across various segments of plant and terminal operations. Here’s how they’re used effectively in real-world applications:
🛢️ Tank Cleaning Support
Before robotic or manual entry, vac crews remove sump waste, settleable solids, and residual fluids. Our combo units’ built-in pressure washing capability is a major advantage when cleaning around nozzles, sump walls, and access points. They also enable hot washing of waxy or heavy crude tanks without needing a separate wash rig.
🔧 Vessel & Exchanger Waste Handling
During chemical cleaning or mechanical work, waste fluids must be removed quickly and without disrupting other workflows. Vac crews recover liquid effluent and solids as exchangers or vessels are opened, keeping work areas clean and compliant. Our combo units are often used to pressure wash nozzle areas post-pull, readying the asset for inspection.
🚨 Emergency Spill Response
Our 24/7 on-call units respond to containment breaches, chemical spills, and fluid leaks. Whether it’s a pit overflow or a collapsed berm, our combo vacs and semi vacs can recover product and wash the site down with hot water to restore safe conditions.
🔄 Confined Space Entry (CSE) Enablement
We remove all visible bulk prior to confined space entry, ensuring tanks, vessels, or sumps meet safe entry conditions. The speed and precision of our crews directly impact schedule and permit timelines. When paired with robotics or entry teams, vac trucks are the critical first step.

Why Vac Truck Work Matters: Safety, Compliance & Throughput
Vac services do more than clean—they protect teams, schedules, and bottom lines.
✅ Confined Space Entry Safety
Entry can’t happen until the tank is pumped out, cleaned, and ventilated. Vac support is the first phase of every confined space entry. Downtime at this stage creates ripple effects across your entire project.
🧪 Environmental & Waste Compliance
Proper handling of oily sludge, emulsion waste, or chemical rinse water is governed by strict codes. Our operators are trained in manifesting, waste stream separation, and ensuring proper chain-of-custody to disposal.
📉 Downtime Risk Reduction
Every delay in waste handling compounds downstream tasks. We scope vac volume and rotation in advance, bringing the right combination of combo and semi vacs to ensure constant flow and zero lag.
Why Solution Services Stands Out
Here’s what makes our approach different:
Hotsy-Equipped Combo Units – No need for extra equipment. Our units handle suction and pressure washing with hot water in one rig.
Scope-Driven Deployment – We scale based on waste volume, tank geometry, and project schedule—not based on guesswork.
Integrated Crews – Our vac operators work alongside robotics, chemical, and mechanical teams with shared permits and aligned safety protocols.
High-Speed Turnaround Support – With dedicated semi vacs for transfer and disposal, waste never holds up your schedule.
Complementary Services That Rely on Vac Truck Support
Vessel & Tank Cleaning – Debulking, foam product removal, degassing rinse recovery
Chemical Circulation Projects – Post-phase fluid removal and nozzle washing
Shutdowns & Turnarounds – Continuous vac staging during high-volume periods
Exchanger Service – Waste recovery during pull, cleaning, and prep
Hydrocarbon Waste Handling – Segregated recovery, manifesting, and offsite disposal coordination

Real-World Vac Truck Scenarios
Industry Sector | Vac Truck Role |
Condensate Tank Prep with Robotics | Two combo units staged to remove sump sludge and wash nozzle areas before robotic sweepers were deployed. Turnaround readiness in under 36 hours. |
Crude Tank Wax Removal | Combo unit with Hotsy burner used to hot wash wax buildup around the sump and lower shell area prior to entry. Significantly reduced manual scrubbing time. |
Midstream Terminal Sump Flush | Semi vac used to remove over 20 m³ of waste water and oil residue. Combo unit followed with hot pressure wash to clean out concrete sump basin ahead of inspection. |
Gas Plant Exchanger Bay Cleaning | Combo vac deployed to recover chemical rinse water and solids during a multi-bay exchanger cleaning scope. Hotsy unit used to pressure wash inlet nozzles, allowing for clear visual inspection by client NDT team. |
Emergency Spill Containment at Terminal | Semi vac mobilized within 2 hours to recover hydrocarbon-contaminated rainwater from secondary containment. Combo vac used to hot wash berm lining and valve sumps. Full containment restored same day. |
Final Thoughts: Don’t Undervalue Vac Truck Support
When your scope depends on timing, cleanliness, and safe entry—vac support becomes a frontline service. At Solution Services, we plan it like that. Our units are maintained to high spec, our operators are project-trained, and our service execution is integrated with your shutdown or maintenance crew from day one.
You can’t afford to treat vac trucks as an afterthought.
We don’t—and neither should your project.

Frequently Asked Questions
What are vac trucks used for in oil and gas?
Vac trucks are used to remove liquids, sludges, and solids from tanks, sumps, vessels, and pits. They support confined space entry, spill response, shutdown cleaning, and maintenance scopes across oilfield sites.
What’s the difference between a combo vac and a semi vac?
A combo vac combines vacuum suction with high-pressure water washing (ours also include hot water burners). A semi vac is used for high-volume waste hauling and off-site transfer.
Do I need vac trucks for tank cleaning?
Yes—vac trucks are essential for pre-cleaning (dewatering, sump removal) and for recovering fluids during and after robotic or manual cleaning.
Are vac trucks compliant with waste handling regulations?
At Solution Services, all our vac units are operated by trained crews who follow proper manifesting, stream separation, and disposal protocols to meet Alberta OH&S and AER compliance.
Can vac trucks handle chemical cleaning waste?
Yes—our vac units are frequently used to recover chemical circulation fluids, degassing rinses, and other hazardous byproducts after cleaning operations.
