A 150-gallon vertical liquid tank from Norwesco for sprayer fills and mixing, a stocky 30-inch shell in 1.5-specific-gravity polyethylene with translucent level-reading walls.
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 150-gallon vertical liquid tank is a versatile mid-small chemical reservoir — enough volume to feed a sprayer fill, run a mixing station, or hold a working supply of concentrate, in a tank that two people can still position by hand. It stands 56 inches tall on a 30-inch diameter, a stable, stockier proportion than the slimmest columns, and weighs 50 pounds empty.
It is molded as one seamless piece of virgin linear polyethylene rated to 1.5 specific gravity, carrying dense liquids up to 12.5 pounds per gallon. The translucent white wall lets you read the level at a glance and reflects sun to keep contents cooler, in FDA-compliant food-grade resin.
Full at the rated gravity it weighs about 1,926 pounds, so a firm level pad carries it without engineered foundation work. The outlet is a 1.25-inch fitting sized for measured transfer, factory-installed and leak-tested, and the 8-inch lid opens the top for fill and inspection. Norwesco's 3-year warranty applies.

Installation and Setup Guide
At 56 inches on a 30-inch base, the 150 is a stable, low-fuss chemical tank. It does not need an engineered slab, but it does need a flat surface and a dosing line matched to the chemistry.
Site Preparation
Stand the tank on a level surface of compacted gravel or a flat concrete pad that supports the full 30-inch base. Just under a ton full, it carries easily on sound ground; the point is even, flat support and, where the contents warrant it, a sealed surface or berm to catch a spill.
Placement and Connections
Roughly a foot of clearance handles routine service. Plumb the 1.25-inch outlet to your pump by the shortest run with chemical-rated flexible tubing, and spec the tubing, gaskets, and valves to the specific chemistry.
Venting
Fit a lid vent so the wall equalizes pressure as you fill and draw, and a chemistry-rated vent if the contents give off vapor.
Maintenance and Long-Term Care
Inspect the 150 the way you would any chemical tank, scaled to its size: shell, seals, base, vent.
Quarterly Inspection Checklist
- Shell: check the translucent wall for distortion or stress whitening.
- Seals and outlet: inspect the 1.25-inch fitting and any inline valve for chemical attack; hand-snug only.
- Base: confirm the tank sits flat and the pad has not settled.
- Vent: verify the lid vent is clear.
Cleaning and Chemical Changeover
Decontaminate per the chemical manufacturer's protocol before switching products, capturing rinsate for disposal. Confirm the incoming chemical against the polyethylene and seals before refilling — never let an incompatible residue meet the next charge.
UV and Weather Protection
The white wall transmits some light, so shade algae-prone or light-sensitive chemistry in strong sun and inspect the wall annually.
Alternatives and Comparisons
The 150-gallon vertical is a practical workhorse between the slim dosing columns and the larger reservoirs. A 150-gallon cone-bottom drains completely through its apex for batch work on a stand; the 175- and 250-gallon verticals step up the storage volume in a similar stocky format.

Frequently Asked Questions
How long will the 150 Gallon Vertical Liquid Storage Tank - Natural White (30" x 56") #41469 last?
Within its 1.5 SG and 120 F ratings and with compatible chemistry, expect 15 to 20 years. Seal compatibility and a flat base are the levers — the seamless shell itself has no joint to fail.
What chemicals can I store in this tank?
At a 1.5 specific gravity rating it carries ag chemicals, fertilizers, and industrial solutions within that range, with food-grade FDA-compliant resin. Not for fuels, solvents, or flammables. Match your chemical and your seals to a compatibility chart before filling.
What kind of foundation does a 150-gallon tank need?
Full at the rated gravity it weighs about 1,926 pounds — just under a ton — so a level surface of compacted gravel or a flat concrete pad carries it without engineered work. Even, flat support across the full 30-inch base is the requirement, plus a sealed surface or berm to catch a spill where the chemical warrants it.
Does this tank come with a warranty?
A three-year manufacturer's warranty covers defects in the molding, the wall, and the factory fittings. Incompatible chemistry, abuse, and physical impact fall outside coverage. Keep your receipt for any claim.
Can I install this tank underground?
No. It is an above-ground tank, and the walls will not resist soil pressure. Buried storage calls for a tank engineered for underground use.
Buying Considerations
Confirm a flat, firm pad for the 30-inch base, a chemical at or under 1.5 SG compatible with the polyethylene and seals, and spill control where the contents warrant it. Freight moves this tank LTL on a pallet, and residential lift-gate delivery is available.
