Horizontal polyethylene tanks deliver low center-of-gravity stability, overhead-clearance compatibility, and dual-use storage-or-transport flexibility. The horizontal cylinder reduces wall hoop stress at fill height vs. an equivalent vertical, and lets you mount the vessel under low ceilings, on skids, or on truck/trailer beds. Catalog covers Norwesco, Snyder Industries, Chem-Tainer, Enduraplas, and Bushman horizontal SKUs from 35-gallon utility to 5,025-gallon commercial.
Applications
Low-clearance bulk water and chemical storage (basement, crawlspace, equipment room)
Truck-bed, trailer-mounted, and skid-mounted transport service
Stationary fuel, lubricant, and AdBlue/DEF dispensing
Agricultural water hauling and nurse-tank service
Underground water storage (cistern-style horizontal models — verify burial rating)
Compliance & Standards
Typically rotomolded to ASTM D1998; FDA 21 CFR 177.1520 resin compliance varies by model (see each product's Specifications). Horizontal tanks for highway transport must include internal baffles to limit slosh and surge loading — confirm baffle configuration on each SKU. For hazmat cargo transport, DOT 49 CFR Part 178 governs design and marking; this catalog is sold for water, non-hazmat ag liquids, and stationary chemical service unless otherwise specified.
Engineering & Selection
Horizontal tanks need a properly sized cradle or stand unless they're sold with integral skids or saddle supports. Cradles distribute weight across the lower 120°–180° of the shell to prevent stress concentration. Never set a horizontal tank directly on flat ground — point-load contact will deform the shell over time. Confirm outlet location (end, underside-center, or both) against your plumbing. Internal baffles reduce hauled-fluid surge by 60–80% — required for any transport above ~25% partial-fill condition.
Freight & Delivery
Tanks ship LTL motor freight from the closest stocking warehouse to your delivery ZIP. Typical transit 5–10 business days. Liftgate available at delivery (per-shipment fee). Always inspect at delivery and note damage on the bill of lading before signing — that is the carrier claim trigger. Bulk-order consolidation reduces per-tank freight 25–40%.

Sizing & Selection
Capacity, length, and outlet position drive selection. Most horizontal tanks list overall length, diameter, and shipping weight. Confirm against your truck bed, skid, or alcove dimensions before ordering. 866-418-1777 for application-engineering review.
