FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
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 22 Gallon Vertical Liquid Storage Tank is the smallest chemical tank in the lineup, a 20-inch cube of capacity for point-of-use dosing, day tanks, and small-batch chemical work. Twenty-two gallons is the right amount of working stock to keep a metering pump fed, hold a shift's worth of a treatment chemical, or serve as a small mixing reservoir on a process skid — without dedicating floor space to a drum.
Norwesco molds it in one seamless piece of virgin linear polyethylene rated to 1.5 specific gravity, so it handles concentrated agricultural and industrial chemistry up to 12.5 pounds per gallon despite its small size. The translucent natural-white wall lets you read the level instantly, which matters most on a small day tank that empties quickly, and UV stabilizers are compounded in for the rare outdoor use.
At 20 inches tall and 20 inches in diameter, it weighs just 12 pounds empty and about 287 pounds full at 1.5 SG. A 0.75-inch NPT outlet suits small-line dosing, and an 8-inch lid handles filling and venting. It carries Norwesco's 3-year warranty against manufacturing defects and, unlike the larger tanks, ships by UPS or FedEx ground rather than freight.

Installation and Setup Guide
This is the only chemical tank in the family small enough to set on a bench or a shelf, so its installation is less about foundations and more about integrating a compact day tank into a process line.
Where to Mount It
At about 287 pounds full, the tank sits comfortably on any sturdy bench, stand, or shelf rated for that weight. Choose a hard, level surface so the small base is fully supported, and position it for an easy gravity feed or a short suction run to your metering pump. The 20-inch cube footprint slips into the corner of a skid or a chemical cabinet that a drum would overwhelm.
Plumbing the Small Outlet
The 0.75-inch outlet is sized for small dosing and transfer lines. Plumb it in tubing or pipe rated for your chemistry, keep the connection flexible at the fitting, and add a small shutoff valve for isolating the tank when you refill it. For a day tank that is filled by hand or by a fill line, a simple level check through the translucent wall prevents overfilling.
Venting
Even a 22-gallon tank needs to breathe. Fit a small screened or relief vent in the 8-inch lid appropriate to your chemical so the tank takes in air as the pump draws it down and releases any vapor safely. Match the vent to the product's volatility rather than to the modest gallon count.
Maintenance and Long-Term Care
A small chemical day tank is easy to maintain precisely because it turns over fast and is light enough to lift, drain, and rinse by hand whenever you change products.
Quick Checks
- Wall and outlet: Backlight the white wall to confirm the level and look for any swelling or crazing from the chemistry, and check the 0.75-inch fitting for weeping.
- Lid and vent: Confirm the 8-inch lid seals and the vent is clear and rated for the current product.
- Mounting: Make sure the bench or stand is sound and the tank sits level.
Changing Chemistries
Because it is so small, this tank is the easiest in the lineup to fully decontaminate. Drain it, rinse per the incoming chemical's procedure, and verify the new product against a polyethylene compatibility chart before refilling — even a thin residual film of an incompatible chemical can react in a small concentrated volume. This is process chemical equipment, not a potable-water container.
Indoor Use
Most 22-gallon tanks live indoors on a skid or bench, where there is no UV exposure and the resin effectively never ages from sunlight. If you do place one outdoors, the compounded UV package protects it, and a periodic glance at the sun-facing side is all it needs.
Alternatives and Comparisons
At 22 gallons the comparison is really about whether a fixed tank beats the alternatives for small-volume chemical work.
Day tank vs. drum or larger tank: A 22-gallon molded tank gives you a clean, plumbable, level-readable reservoir that integrates into a process line far better than a portable drum, with a proper outlet and lid instead of a bung. If your dosing demand grows, stepping up to a larger vertical liquid tank adds capacity at the cost of footprint and freight handling. Against a steel or composite container, the seamless polyethylene resists a broad range of chemistry and will not corrode, making it the low-maintenance choice for a permanent small day tank.

Frequently Asked Questions
How long will the 22 Gallon Vertical Liquid Storage Tank last?
Used within its 1.5 SG and 120 F ratings and kept on a sound surface, a small tank like this easily lasts 15 to 20 years, often longer, because day tanks usually live indoors and lead an easy life. The seamless molded body has no joint to fail, and the compounded UV package covers any outdoor use. Compatible chemistry and clean handling are what carry it the distance.
What chemicals can I store in this tank?
It is rated to 1.5 specific gravity and accepts concentrated agricultural and industrial chemistry up to 12.5 pounds per gallon, which is why it makes a good day tank for treatment and dosing chemicals. Always confirm a specific product on a polyethylene compatibility chart, avoid fuels and flammables, and remember that in a small volume an incompatible residual reacts fast. It is chemical-process equipment, not a drinking-water tank.
Does this tank come with a warranty?
Norwesco backs it with a 3-year warranty against manufacturing defects in materials and workmanship under normal use. The coverage is for molded-in faults like pinholes and cracks, not damage from incompatible chemicals, overloading beyond the rated density, or impact. Keep your receipt for any claim.
Can I install this tank underground?
No. Even at 22 gallons this is an above-ground tank with walls that are not built to resist soil pressure, and burying it would void the warranty. For any below-grade need, our underground cistern and septic products are the reinforced choice.
Buying Considerations
Two things to confirm before this 22-gallon tank ships. First, your chemistry, checked against a polyethylene compatibility chart — even at 1.5 SG and small volume, the product must be compatible with the resin. Second, the mounting surface, a sturdy bench or stand rated for the roughly 287-pound full weight. A practical bonus at this size: the tank ships by UPS or FedEx ground rather than freight, so it arrives quickly and inexpensively. Listed at $140.00 before shipping, quoted to your ZIP.
