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 75 Gallon Vertical Liquid Storage Tank in translucent white is a small chemical and fertilizer tank, holding 75 gallons in a slim 49-inch body on a 23-inch base. It is a convenient size for point-of-use chemical supply, small-batch metering, or a compact reserve in a tight chemical layout.
Its seamless virgin-linear-polyethylene wall, rated to 1.5 specific gravity, is engineered for dense agricultural and industrial liquids up to 12.5 pounds per gallon. Operators read the level instantly through the translucent white wall, which reflects sun to hold the stored chemical's temperature down.
Empty, the tank weighs just 29 pounds; filled with a 1.5-SG liquid it puts roughly 967 pounds onto its small 2.9-square-foot footprint. The tank discharges via a factory 2-inch NPT outlet and is accessed through an 8-inch lid. Since the inlet is omitted, drill and mount a bulkhead where your system needs it.

Installation and Setup Guide
At 49 inches tall on a 23-inch base, this 75-gallon tank is a slim, light chemical vessel — a full 1.5-SG load is under a thousand pounds — so the install hinges on a flat base, a secure mount, and clean chemical plumbing rather than on managing weight. Its narrow base for its height means a tip restraint is worth fitting from the start.
Site Preparation
Set it on a small level surface sized past the 23-inch base — a pad, a load-rated platform, or flat concrete — shimmed flat so the 49-inch body stands true. Being light and fairly slim, the tank is easy to knock over, and a chemical spill is a worse outcome than a water spill, so strap or fasten the upper body wherever it could be bumped.
Placement and Connections
Take the discharge off the factory 2-inch outlet and break it with a chemically compatible flexible coupling so the tank can shift slightly without straining the bulkhead. There is no inlet from the factory, so set a compatible bulkhead where your fill plumbing requires. Use chemical-rated plumbing and hand-tighten the poly threads only a quarter turn past snug, since the smaller fittings strip easily.
Venting
Even 75 gallons of chemical must breathe as it cycles. Hold the 8-inch lid's vent open to let air track the liquid, fitting a chemical-rated pressure/vacuum relief vent where the chemistry is volatile. A sealed small tank can dimple under a brisk pump-out, so keep the relief path clear and matched to the stored liquid.
Maintenance and Long-Term Care
A small 75-gallon chemical tank is quick to inspect and easy to service, with the translucent wall reading the level instantly. Maintenance is chemical-tank work, not potable, focused on compatible fittings, a clear vent, and decontamination between products.
Quarterly Inspection Checklist
- Quick visual: Scan the slim 49-inch body through the translucent wall for bulging, stress whitening, or weeping at the fitting.
- Outlet and bulkhead check: Look over the 2-inch outlet and your fitted inlet for chemical seepage, being careful not to over-torque the small fittings.
- Mount check: Confirm the support is sound and the light, slim tank has not shifted or begun to lean.
- Vent verification: Verify the 8-inch lid's vent or pressure/vacuum relief remains clear and appropriate for the stored chemical.
Cleaning
Decontaminate to the chemical manufacturer's guidance whenever you change products; a rinse alone does not clear residue from the wall. The 2-inch outlet empties the tank while the 8-inch lid opens it for inspection under proper chemical-handling precautions. It serves chemical storage exclusively and must stay out of potable-water duty.
UV and Weather Protection
The translucent white wall reflects sunlight and carries UV stabilizer in the resin, and a 75-gallon tank is small enough to keep under cover or indoors, sparing it most UV exposure. If it lives outdoors, check the sun-facing side yearly for chalking and relocate it to shade if convenient.
Alternatives and Comparisons
This 75-gallon vertical suits point-of-use and small-batch chemical supply, where the 50- and 40-gallon tanks handle smaller needs and the 100- and 150-gallon tanks step up. Pick the size based on how much chemical you cycle and how often you top it up.
Vertical vs. Horizontal: Vertical tanks use less floor space for the same capacity but require more overhead clearance. If you have height restrictions, consider a horizontal or low-profile tank. Vertical tanks also drain more completely due to gravity — the liquid column above the outlet creates positive pressure all the way to the last few gallons.

Frequently Asked Questions
How long will the 75 Gallon Vertical Liquid Storage Tank - Natural White (23" x 49") last?
On a flat support, within its 1.5 SG rating, and properly decontaminated between products, this 75-gallon tank lasts well over a decade and often longer, since a small tank is easy to keep out of harsh sun. The typical life-limiter is chemical incompatibility rather than age.
What chemicals can I store in this tank?
Good to 1.5 specific gravity, it stores agricultural chemicals, liquid fertilizers, and most industrial solutions up to 12.5 pounds per gallon — just confirm compatibility for each chemical on a polyethylene chart first. Steer clear of fuels, solvents, and flammables; the tank is meant for chemicals, not drinking water.
Does this tank come with a warranty?
Yes — Norwesco's 3-year warranty handles manufacturing defects in normal use: factory faults, not overloading beyond 1.5 SG, chemical attack, a drop, or misuse. Keep proof of purchase on hand for any warranty claim down the road.
Can I install this tank underground?
No. Even at 75 gallons this is an above-ground tank whose flat wall cannot resist soil pressure; burying it would collapse it and void the warranty. Below grade, choose a small ribbed underground tank rated for soil loads.
Buying Considerations
Confirm a small flat support and a secure mount for a slim, light tank, place it near the process it feeds to shorten the chemical plumbing, and verify the chemistry against polyethylene before dedicating the tank to it.
