75 Gallon Vertical Liquid Storage Tank - Natural White (23" x 50"): Complete Buyer's Guide
A 75-gallon vertical liquid storage tank from Norwesco, 23 inches across and 50 inches tall, seamlessly rotomolded in 1.5-specific-gravity polyethylene for dosing and day-supply of agricultural and industrial chemistry.
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.
Installation and Setup Guide
A 75-gallon chemical tank on a 23-inch base is a compact dosing vessel that goes almost anywhere a flat surface allows. Setup is quick; the care goes into the plumbing and the spill plan, not the foundation.
Site Preparation
Stand the tank on a firm, level surface that supports the full 23-inch base — a sealed floor, a sturdy bench, or a rated stand. Make sure the whole bottom sits flat, and where the contents are a concentrate, put the tank over a sealed surface or a drip tray so any leak is caught.
Placement and Connections
Leave about a foot of clearance to reach the fitting and lift the lid. Plumb the outlet to your metering or transfer pump by the shortest run using chemical-rated flexible tubing, and match the tubing, gaskets, and any valve to the specific chemistry rather than just the thread size.
Venting
Give the tank a lid vent so the slim 50-inch wall does not pull inward as you draw it down, and if the chemical off-gasses, site the tank for ventilation and fit a vent suited to the vapor.
Maintenance and Long-Term Care
On a small chemical tank, the seals and the chemistry need watching more than the rugged shell.
Quarterly Inspection Checklist
- Shell: a glance through the translucent wall catches any distortion or stress whitening.
- Seals and outlet: inspect the fitting, tubing, and valves for swelling or hardening that signals chemical attack; hand-snug only.
- Spill control: confirm the drip tray or sealed surface is clean and intact.
- Vent: verify the lid vent is clear.
Cleaning and Chemical Changeover
Before changing chemicals, flush the tank per the product manufacturer's instructions and capture the rinsate for disposal. Confirm the incoming chemical is compatible with the polyethylene and the tubing and seals before refilling, and keep a changeover note to avoid cross-contamination on a frequently switched dosing tank.
UV and Weather Protection
The white wall transmits some light, so keep light-sensitive contents shaded or indoors. For a bench install this rarely matters.
Alternatives and Comparisons
The 75-gallon vertical is a dosing-and-day-tank size in a slim 23-inch format. If your process needs complete drainage and self-rinsing between batches, a small cone-bottom empties through its apex on a stand. For more capacity in the same narrow footprint, the 100- and 105-gallon verticals are the next steps.

Frequently Asked Questions
How long will the 75 Gallon Vertical Liquid Storage Tank - Natural White (23" x 50") last?
Within its 1.5 SG and 120 F ratings and with compatible chemistry, this tank will serve well past 15 years — the seamless molded shell has no joint to fail, so seal compatibility and sun exposure are the real life-limiters.
What chemicals can I store in this tank?
Rated to 1.5 specific gravity, it handles agricultural chemicals, fertilizers, and industrial solutions within that density, and the resin is FDA-compliant for food-grade liquids. Not for fuels, solvents, or flammables. Verify your chemical and your tubing and seals against a compatibility chart before filling.
Does this tank come with a warranty?
Norwesco's warranty covers manufacturing defects under normal use: molding flaws, pinholes, and factory fitting faults. Excluded are incompatible chemistry, misuse, and impact damage. Keep your receipt for any claim.
Can I install this tank underground?
No — this is an above-ground tank whose walls cannot take soil pressure. For any buried installation, choose a tank built for underground service.
Buying Considerations
Confirm a flat, firm surface for the 23-inch base, a chemical at or under 1.5 SG compatible with the polyethylene and your seals, and a spill-control surface or tray if the contents are a concentrate. Freight is easy — this tank ships UPS or FedEx ground and typically arrives within 5 to 7 business days.
