Fliteway designs and builds complete environmental treatment systems packaged inside custom enclosures of every scale — from small portable trailers to full-size prefabricated buildings. The entire treatment train is fabricated, wired, programmed, and tested in our Cudahy, Wisconsin facility, then shipped ready for hookup and start-up.
A containerized system is more than a treatment train bolted to a skid. It is a purpose-built enclosure — insulated, lit, climate-controlled, contained, and electrified — with the complete process, controls, and safety package installed and proven before it leaves the shop. For the site team, a containerized delivery means setting the unit in place, connecting utilities, and walking through start-up, not coordinating mechanical, electrical, controls, and HVAC trades across weeks of field work.
Fliteway has been containerizing remediation equipment for decades. We build the structure, the process piping, the electrical distribution, the control panels, and the instrumentation under one roof, which lets us test the system as a whole before it ships. When the project calls for something bigger than a standard shipping container, we scale up to prefabricated buildings. When the project calls for something smaller or mobile, we scale down to trailers. The treatment train drives the enclosure, never the other way around.
This is the work we are happiest doing: complete, coordinated, tested systems that arrive ready to run.
Enclosure Types
Fliteway sizes the enclosure to the project. Every platform below includes factory-installed mechanical, electrical, controls, and safety systems — the only decision is how mobile, how large, and how permanent the deployment needs to be.
Portable Trailers
Small DOT-compliant trailers for pilot testing, emergency response, and short-duration or relocating projects. Quick-disconnect utility connections, cam-lock piping, and plug-and-play electrical let a crew mobilize, operate, and demobilize without permanent infrastructure. Ideal for investigations, stop-gap treatment, and proof-of-concept deployments.
Semi-Truck & 53-ft Mobile Trailers
Road-legal 48-ft and 53-ft dry-van and flatbed platforms for mobile treatment programs that move between sites. Full climate control, LED lighting, vent fans, insulation, secondary containment, and a single lockable access point. Fliteway has delivered 25-GPM PFAS treatment trailers on this platform for multi-site remediation programs.
Standard CONEX Shipping Containers
Modified 8-ft, 10-ft, 20-ft, and 40-ft ISO shipping containers for permanent and semi-permanent installations. Weather-tight, secure, stackable, and shippable by truck, rail, or sea. The most common platform for long-term SVE, groundwater, and PFAS treatment systems. Interior outfitted with insulation, lighting, HVAC, and the full treatment train.
Double-Size & Combined Enclosures
Double-wide, side-by-side, or end-to-end container configurations when a single CONEX cannot fit the treatment train. Used for higher-flow SVE, combined vapor and water treatment, and systems with large ancillary equipment (compressors, oxidizers, heat exchangers). All piping and electrical are coordinated across enclosures for a single unified tie-in.
Full-Size Prefabricated Buildings
Purpose-built modular buildings for the largest and most permanent deployments — multi-process treatment plants, long-term O&M facilities, and installations that need integrated office, instrumentation, and storage space alongside the treatment system. Engineered to local structural, electrical, and fire codes and delivered turnkey.
Custom Hybrid Configurations
Some projects call for a hybrid — a CONEX tied into a skid pad, a trailer paired with a containerized blower package, or a building with an attached tank farm. Fliteway engineers the entire delivery as one coordinated package so the site team receives a single turnkey system no matter how many enclosures it spans.
What’s Inside Every Enclosure
Regardless of the outer shell, a Fliteway containerized delivery includes the same coordinated package of mechanical, electrical, controls, and safety systems — all installed, wired, and tested in our shop before the unit ships.
Process Train
Blowers, pumps, treatment vessels, moisture separators, phase separators, air strippers, GAC vessels, chemical feed systems, piping, valves, and instrumentation — all selected, sized, and integrated for the project’s specific flow, pressure, and contaminant profile.
Electrical & Controls
Main disconnect, distribution panel, motor control center, VFDs, and a UL 508A-listed control panel. PLC- or relay-based logic with an HMI, safety interlocks, alarm annunciation, and remote telemetry for off-site monitoring. Single utility tie-in point for the site electrician.
Climate & Lighting
Spray-foam sound and thermal insulation on walls and ceiling, unit heaters for freeze protection, thermostat-controlled ventilation, interior LED lighting, and GFCI receptacles. Year-round operation in any climate, with bed-liner non-slip floor coating for safe personnel access.
Containment & Safety
Secondary containment with leak detection switch, E-Stop, fire extinguisher, lockable personnel access doors, equipment guards, and all labeling and signage required for operator safety and regulatory compliance.
Design, Build, Test, Ship
Every containerized project follows the same disciplined workflow — from concept through factory acceptance testing to field start-up.

Shipment, Start-up, and Support
Delivery and placement coordinated with the site team, followed by field start-up, operator training, and as-built drawings. Long-term O&M, remote telemetry, and spare-parts support are available for every platform.
What Containerized Treatment Systems Are Used For
Fliteway packages complete treatment trains for the contaminants and site conditions environmental consultants deal with most. Each application below has shipped from our Cudahy, Wisconsin shop inside trailers, CONEX containers, or prefabricated buildings.
Groundwater Pump & Treat
Extraction well manifolds, transfer and metering pumps, oil/water separators, air strippers, bag filtration, and liquid-phase GAC polishing — assembled, plumbed, and wired as one enclosure. Typical flows from a few GPM pilot systems to 200+ GPM full-scale plants, with discharge instrumentation sized to permit limits.
PFAS Treatment
Granular activated carbon, ion-exchange resin, and foam-fractionation platforms for PFOA/PFOS and short-chain PFAS, packaged with pre-filtration, breakthrough sampling ports, and change-out access designed into the enclosure. Containerization suits PFAS work especially well because treatment trains and media strategies often evolve as regulations and monitoring data change — the platform moves and adapts.
Petroleum Hydrocarbons & Chlorinated Solvents
SVE and dual-phase extraction systems for UST releases, dry-cleaner sites, and industrial solvent plumes: rotary-lobe and liquid-ring blowers, knockout tanks, vapor-phase GAC or catalytic/thermal oxidation, and LEL monitoring with automatic shutdown — the classic remediation package, delivered as a single tested unit.
Construction & Industrial Dewatering
Temporary treatment for excavation and foundation dewatering on brownfield and urban construction sites: solids settling, bag filters, GAC, and flow totalization to meet sewer-discharge or surface-water permits. Rental-fleet units deploy in days and demobilize just as fast when the pour is done.
Containerized vs. Stick-Built Treatment: How to Choose
Choose containerized when:
The remedy has a defined life (5–15 years) and the asset should retain value or redeploy afterward
Schedule matters — factory build and FAT compress field commissioning from weeks to days
Site space, security, or weather make open-air or field-built equipment impractical
The treatment train may change (PFAS media strategies, step-down remedies)
The project is a rental, pilot test, or interim remedial measure
A fixed treatment building fits better when:
The system is very large or permanent (decades of operation at one location)
Equipment dimensions exceed practical enclosure and highway-transport limits
The facility integrates into a larger plant with shared utilities and structures
Fliteway builds both — and hybrid approaches, like containerized process trains installed inside client buildings — so the recommendation follows the project, not our product line.

Frequently Asked Questions
What is a containerized treatment system?
A containerized treatment system is a complete environmental treatment platform — blowers, pumps, piping, treatment vessels, electrical, controls, instrumentation, lighting, HVAC, and safety systems — all pre-installed and tested inside a transportable enclosure before it ever reaches the project site. Fliteway builds these enclosures at every scale: small portable trailers, DOT-compliant semi-truck trailers, 20-ft and 40-ft CONEX shipping containers, double-wide enclosures, and full-size prefabricated buildings. Containerization moves the vast majority of mechanical, electrical, and controls work from the field into a controlled shop environment, which shortens commissioning, reduces rework, and gives the site team a single coordinated package to install.
What sizes do your containerized systems come in?
Fliteway engineers each enclosure to the project rather than forcing a one-size-fits-all footprint. Typical options include small portable trailers for pilot tests and rapid-response deployments; 40-ft and 53-ft semi-truck trailers for mobile treatment platforms that move between sites; 8-ft, 10-ft, 20-ft, and 40-ft CONEX-style shipping containers for permanent and semi-permanent installations; double-stacked or side-by-side containers for higher-capacity systems; and full-size prefabricated buildings when the site calls for a purpose-built treatment facility. Every enclosure is sized around the treatment train inside, not the other way around.
What is included inside a Fliteway containerized system?
A typical Fliteway containerized system includes the complete process train (blowers, pumps, treatment vessels, separators, piping, and instrumentation), a pre-wired electrical distribution panel, PLC- or relay-based controls with an HMI, motor starters and VFDs, safety interlocks and alarms, interior lighting, GFCI receptacles, spray-foam insulation, HVAC and unit heaters for year-round operation, bed-liner non-slip floor coating, secondary containment with leak detection, personnel access doors, and lockable exterior doors. Every connection the field electrician and mechanical contractor need is terminated and labeled at a single point of entry.
What contaminants can a containerized treatment system address?
Fliteway containerized systems treat the full range of soil-vapor and groundwater contaminants encountered in environmental remediation: petroleum hydrocarbons from UST releases (benzene, toluene, ethylbenzene, xylenes), chlorinated solvents (PCE, TCE and daughter products), PFAS compounds including PFOA and PFOS via granular activated carbon, ion exchange, and foam fractionation, dissolved metals, and suspended solids from construction and industrial dewatering. The enclosure is the delivery method — the treatment train inside is engineered to the site’s contaminants, flow rates, and discharge permit.
When should I choose a containerized system instead of a fixed treatment building?
Containerized systems are usually the right choice when the remedy has a defined lifespan of roughly five to fifteen years, when schedule pressure favors factory fabrication and testing over months of coordinated field trades, when the treatment approach may change over the project life (common on PFAS sites), or when the system should retain value and redeploy to another site afterward — including rentals, pilot tests, and interim remedial measures. A stick-built treatment facility makes more sense for very large permanent plants, equipment that exceeds highway-transportable dimensions, or systems integrated into a larger facility with shared utilities. Fliteway builds both and will recommend the configuration that fits the project.
How does containerization speed up project delivery?
Because Fliteway fabricates, wires, programs, and tests the entire system inside the enclosure at our Cudahy, Wisconsin facility, field commissioning typically compresses from weeks of coordinated trades work into a few days of hookup and start-up. Factory acceptance testing (FAT) verifies pressure integrity, instrumentation loops, controls logic, motor operation, and alarms before the enclosure ships, so on-site work is limited to placement, utility tie-ins, and start-up walkdowns. For rental and emergency-response projects, a pre-built containerized system can be on the road within days.
