EnviroBox — Own It, Don't Rent It

Rental fees stack up month after month with nothing to show for it. A Municipal Tank Works tank is a capital asset — it holds resale value and its total cost of ownership beats extended rental within 18–24 months. Need temporary capacity first? We offer rental on our own tanks by request — same shop-welded quality, no surprises. Rental payments can count toward purchase.

📐

EnviroBox — Built to Your Exact Spec

Our tanks come in any dimension, any lining, any nozzle layout — configured to your exact process, your site, and your standards. Not an off-the-shelf guess. No adapters. No workarounds.

⏱️

EnviroBox — 25-Year Service Life

Our shop-welded tanks are built for permanent installation with a 25-year minimum service life and full corrosion protection from day one. Not temporary duty equipment — a capital asset engineered for the long haul.

Construction

How EnviroBox
Tanks Are Built.

Every EnviroBox tank — EnviroBox, DataFlow, and FireWater lines — is built on the same proven structural platform at our Canton, Ohio facility. Not assembled in the field. Not adapted from a trailer. Shop-welded, blast-cleaned, primed, and coated before it leaves our door.

01
Solid Shop-Welded Body

All six faces fully welded in our shop — closed, solid, no field seams. Carbon steel plate sized to your volume and pressure requirements.

02
Full-Height Structural Rib Grid

Deep structural channel ribs on all vertical faces carry the full hydrostatic load. No thin-wall construction — ribs run full height and connect at every horizontal band.

03
Solid Walkable Roof Plate

A genuine flat steel plate — not a shell, not a lid. Thick enough to walk on safely. Manway, vent, and accessories bolt directly to it.

04
Heavy I-Beam Skid Base

Three longitudinal I-beam runners with cross-member tie bars. Sets directly on a grade pad — no concrete foundation required.

05
Ladder with Elbow Transition

Fixed vertical ladder from grade to roof. Quarter-arc elbow at the top transitions rails from vertical to horizontal — continuous handhold as you step onto the roof deck.

06
OSHA Guardrail — Opening at Ladder

Orange OSHA-compliant rail with toe plate on all four sides. Deliberate gap at the ladder side lets personnel step off cleanly — not an afterthought, an engineered feature.

Vertical Stacking

2× or 3× Volume.
Same Footprint.

No other tank on the market stacks like EnviroBox. Upper unit skid welds directly to lower unit roof plate — zero gap, one continuous vessel. Available across all three product lines.

01
Flush Weld Connection

Upper skid welds directly to lower roof plate. No saddle frame, no gap. A dark seam band and weld highlights mark the joint — structurally and visually one vessel.

02
One Ladder, Full Height

A single ladder runs from grade to the top unit's roof — rails, rungs, elbow transition, and handrail extensions in one continuous run up the entire stack.

03
Common Riser & Single Connection

External riser equalizes all chambers. Fill, vent, and outlet piping run as one integrated circuit — one connection point to your process or pump station.

04
No Civil Work Required

Same grade pad as a single unit. No new concrete, no new footprint. Stack a second or third unit as your capacity needs grow.

Construction Sequence

Shop-Welded Modular Tank.
Built in Stages.

Interactive 3D animation — watch a 53′ × 8′-6″ × 24′ modular tank go from flatbed delivery to fully assembled, course by course.

Three courses of externally braced steel panels, crane-set one at a time onto a gravel pad. Each course bolts to the one below — deck, rails, and ladder installed last. Watch the full sequence on loop.

Modular Scale-Out

Add Capacity.
Just Add a Tank.

4 × 40-foot EnviroBox vessels on a shared base manifold.

Four identical 40-foot EnviroBox units, manifolded at the base. Inflow enters the bottom of the lead tank at one end of the row and exits the bottom of the trailing tank at the opposite end — every additional tank adds capacity without re-engineering the system.

drag to orbit · scroll to zoom
Phase 01

Bottom Inlet

Process water enters the bottom of the first tank through the base manifold — fed from a pump, well, or upstream header.

Phase 02

Manifold Equalize

The shared base manifold carries water tank-by-tank down the row. All four vessels rise to a common level — no pumps, no valves.

Phase 03

Bottom Outlet

At steady state, water discharges from the bottom of the far tank at the opposite end. Add a fifth, sixth, or nth unit on the same manifold to grow with demand.

From the Field

What Our Customers Say.

"

We were paying over $5,000 a month in rental costs for produced water storage. Two EnviroBox units covered the same volume, we own them outright, and we broke even in under 20 months. Should've done it sooner.

"

Our AHJ required NFPA 22 compliance for the fire water tank — MTW came back with a fully compliant FireWater unit, PE-stamped drawings, and delivery in eight weeks. Every other vendor we contacted couldn't meet the standard. Exactly what we needed.

The approval drawing process was fast and thorough. We specified our nozzle layout, lining, and color on Monday. We had drawings in our hands by Wednesday. Nothing went to the shop floor until we signed off. That's how it should work.
