Rectangular Tank Solutions
From a standalone 5,000-gallon shop unit to a 10-tank gravity-linked system storing millions of gallons — EnviroBox delivers rugged, scalable rectangular storage for every industry.
The deep structural rib grid carries hydrostatic load while maximising footprint efficiency. Flat walls butt cleanly against buildings, berms, and each other — no wasted space.
Link multiple tanks end-to-end or in parallel via gravity manifolds. No pumps required between units — natural head pressure moves product through your system.
Specify manways, nozzle positions, ladders, guardrails, baffles, coatings, and integrated pump houses. Every tank is built to your exact requirements.
Product Range
Whether you need a single shop unit or a multi-million-gallon gravity system, EnviroBox has a configuration to match your site and process.
The workhorse of small-scale operations. A single shop-welded rectangular tank for washdown water, chemical storage, process liquids, and more. Delivered ready to set.
Ten massive shop-welded units manifolded together by gravity — no inter-tank pumping required. Ideal for produced water, stormwater retention, bulk chemical storage, or emergency containment. System scales as your needs grow.
System Design
Tanks are positioned in a slight grade or manifolded at a common low point. Product flows from tank to tank and to process by gravity head alone — eliminating inter-tank transfer pumps and reducing maintenance dramatically.
Tanks are sited at a common elevation or a deliberate slope for natural head.
Outlet nozzles connect to a shared header pipe. Isolation valves let any unit be taken off-line independently.
Add tanks to the manifold at any time. Each unit adds roughly 1 million gallons to system capacity.
