750 Gallon Vertical Liquid Storage Tank - Natural White (46" x 107"): Complete Buyer's Guide
A 750-gallon vertical liquid tank from Norwesco built tall and slim on a 46-inch base, in 1.5-specific-gravity polyethylene for bulk chemistry where floor space is scarce.
Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.5 — the tank is engineered for liquids up to 1.5× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Product Overview
The 750-gallon vertical liquid tank is a bulk chemical reservoir in a deliberately slim package — 107 inches tall on just a 46-inch diameter — so it delivers three-quarters of a thousand gallons of ag or industrial chemistry on barely 11.5 square feet of ground. That tall narrow build is the pick when floor space is scarce, and the deep column gives strong gravity feed to the outlet. Empty, the shell is 160 pounds.
A seamless single molding of virgin linear polyethylene rated to 1.5 specific gravity holds dense liquids to 12.5 pounds per gallon. The translucent white wall reveals the level through the side and reflects sun to cool the contents, with FDA-compliant food-grade resin.
Full at the rated gravity it weighs about 9,542 pounds — nearly five tons concentrated on that small base — so the pad must be both firm and dead level. The outlet is a 2-inch fitting for real transfer flow, factory-installed and leak-tested, and the 16-inch lid opens the top for inspection. Norwesco's 3-year warranty applies.

Installation and Setup Guide
The 750's tall, slim build is a space-saver that is unforgiving of a tilt: a 107-inch column concentrating five tons onto a 46-inch base will lean on an out-of-level pad. Level is the whole game.
Site Preparation
Build a four-inch compacted gravel pad or a concrete slab sized to the full 46-inch base and flat to within a quarter inch across the circle. The small footprint and tall shell magnify any unevenness into both a stress point and a lean, so level it carefully and clear out every stone. Add a sealed surface or berm if the chemical warrants containment, and pick a spot sheltered from strong wind.
Placement and Connections
Keep two feet of clearance all around for service and so the tall tank never rests against a structure. Plumb the 2-inch outlet by the shortest run with chemical-rated flexible couplings, and match every gasket and valve to the chemistry.
Venting
The deep column pulls a strong vacuum on a fast draw, so size the vent generously to your flow and fit a chemistry-rated relief vent if the contents off-gas.
Maintenance and Long-Term Care
Inspect the tall 750 from the base up: the lower wall takes the deepest column's pressure, and the seals and vent need a chemical tank's usual attention.
Quarterly Inspection Checklist
- Lower wall: the bottom band of a 107-inch column carries the highest hoop stress — inspect it hardest for bulging or stress whitening.
- Seals and outlet: check the 2-inch fitting and valves for chemical attack; hand-snug only.
- Plumb and pad: confirm the tall tank stands straight on a flat, fully supported base.
- Vent: check the relief vent is clear, since a blockage warps a deep tank fast.
Cleaning and Chemical Changeover
Before switching products, decontaminate to the manufacturer's protocol and capture the rinsate for disposal. Confirm the incoming chemical against the polyethylene and all seals before refilling, and never let an incompatible residue meet the next charge.
UV and Weather Protection
The reflective white wall runs cooler but transmits some light; in strong sun inspect the wall annually and consider shade for the deep column of contents.
Alternatives and Comparisons
This 46-by-107 build is the space-saver among 750-gallon tanks. Where ground is plentiful a wider 750 sits lower and more stably; where you are pinned against a wall, this slim column is the answer. A 750-gallon cone-bottom drains completely for batch processing on a stand, at the cost of even more height. Step up to the 1,000 or 1,500 verticals for greater bulk.

Frequently Asked Questions
How long will the 750 Gallon Vertical Liquid Storage Tank - Natural White (46" x 107") last?
With compatible chemistry, a flat pad, and use within its 1.5 SG and 120 F limits, expect 15 to 20 years. A tall tank is especially sensitive to its foundation — a true base keeping the column plumb is what carries the seamless shell to the long end.
What chemicals can I store in this tank?
Its 1.5 specific gravity rating handles ag chemicals, fertilizers, and industrial solutions within that band, with FDA-compliant food-grade resin. Not for fuels, solvents, or flammables. Verify the chemistry and the seal materials on a compatibility chart before filling.
What kind of foundation does a 750-gallon tank need?
Full at the rated gravity it weighs about 9,542 pounds — nearly five tons — concentrated on a 46-inch base, so a four-inch compacted gravel pad or a concrete slab is the minimum, and it must be dead level and stone-free. Because the tank stands 107 inches tall, an out-of-level pad shows up as a lean and accelerates wear, so level it with care.
Does this tank come with a warranty?
Norwesco warrants the shell for three years against molding, wall, and factory-fitting defects. Overload, a faulty foundation, incompatible-chemical attack, and impact fall outside coverage. Keep records and install photos for any claim.
Can I install this tank underground?
No. The walls of a tall vertical chemical tank cannot take soil loading — burial means collapse and a voided warranty. Below-grade storage requires purpose-built underground tankage.
Buying Considerations
Three checks before ordering: a dead-level, firm pad for the small base under five tons; a chemical at or under 1.5 SG compatible with the polyethylene and seals; and a freight plan, since at 107 inches tall this tank ships LTL by flatbed and needs a forklift to unload.
