210 Gallon Vertical Liquid Storage Tank: Complete Buyer's Guide
A 210-gallon vertical that earns its tall, slender 32-inch stance — enough chemical or fertilizer capacity for a working spray program, packed into a footprint that tucks against a wall. The wide 2-inch outlet and 16-inch lid make it as easy to fill and draw as it is to read through the translucent Norwesco wall.
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
Two hundred ten gallons is a working volume — enough to charge a sprayer through a season's pass, feed a metering system, or hold a fertilizer blend between applications — and the 210 Gallon Vertical Liquid Storage Tank delivers it in a deliberately slender form. At 32 inches in diameter and 67 inches tall, the tank goes up rather than out, claiming little floor while still holding a meaningful charge of agricultural chemical or industrial solution.
The tank is rated to 1.5 specific gravity, carrying liquids up to 12.5 pounds per gallon — the band that covers most fertilizers, herbicides, and water-based industrial chemistries. Empty it weighs 59 pounds; a full charge at the rated density reaches about 2,686 pounds, and the taller column puts more hydrostatic load on the lower wall than a squat tank would, so a level base is essential. Norwesco molds the body as one seamless piece of polyethylene, with no weld line for aggressive chemistry to exploit.
The fittings are sized for real throughput. A 2-inch NPT outlet is molded and leak-tested at the factory, generous enough to fill a sprayer quickly or feed a transfer pump without throttling, and the 16-inch lid opens wide for bulk filling, venting, and interior inspection. The translucent white wall lets the operator track the level up the tall column and watch the contents without opening the tank, while reflecting sunlight to moderate temperature in the field.
This is chemical and liquid storage equipment rated within its 1.5 specific-gravity envelope — not a drinking-water tank — backed by Norwesco's 3-year warranty against manufacturing defects.

Installation and Setup Guide
A tall, slender chemical tank is space-efficient but top-heavier than a squat one, so a dead-level base does double duty: it carries the load and keeps the column plumb.
Site Preparation
Pick a well-drained spot and build a firm, level surface — sealed concrete suits a chemical tank — flat within about 1/4 inch across the 32-inch diameter. The 2,686-pound full charge concentrates a tall column's weight on the base, so it must carry that load without settling. A high spot under one edge both stresses the wall and tips a tank that is already taller than it is wide.
Placement and Connections
Leave about 12 inches of clearance around the tank for the level read, the lid, and the plumbing. Plumb the 2-inch NPT outlet with a chemical-rated full-port valve at the tank; the wide outlet is meant to move liquid fast, so do not throttle it with reducers right at the boss. Select every valve, gasket, and hose for compatibility with your chemistry, and take the first connection in flexible chemical-rated hose so the tall poly column can move with temperature without cracking the fitting.
Venting
The tank must breathe both ways — the deeper column makes vacuum collapse a real risk if a fast draw outpaces the vent. A screened vent handles plain liquids; many agricultural and industrial chemistries call for a pressure/vacuum relief vent rated for the specific product. Keep eyewash and spill response accessible where open chemical is handled.
Maintenance and Long-Term Care
The routine for a tall chemical tank adds attention to the lower wall and the column's plumb, on top of the usual chemistry watch.
Quarterly Inspection Checklist
- Lower-wall focus: Through the translucent wall, inspect the lower third of the column most closely — that is where hydrostatic load peaks. Crazing, bulging, or swelling there is an early, urgent warning.
- 2-inch outlet and valve: Check the wide outlet and its valve for weeping or chemical staining; the larger boss is a larger potential leak path. Hand-snug threads, never with a pipe wrench.
- Plumb and base: Confirm the tall tank still stands plumb and bears evenly; a settled corner is more consequential on a tank taller than it is wide.
- Vent: Verify the vent is clear and adequate for the draw rate; a tall tank drawn fast through a clogged vent will pull its walls in.
Decontamination Between Chemistries
Flush and decontaminate the tank, 2-inch outlet, and hose to the chemical manufacturer's procedure before changing products. The taller column holds a meaningful volume, and residue reacting with the next charge is a hazard, not a nuisance. This is chemical equipment and is never returned to potable use.
UV and Long-Term Care
The resin carries UV stabilizers, but check the sun-facing side annually for chalking if the tank lives outdoors, and shade it where UV is intense. The translucent wall will gradually opacify with long sun exposure — cosmetic until crazing appears. Keep a log of wall condition and hardware changes to track the tank's true service life.
Alternatives and Comparisons
The 210 Gallon Vertical Liquid Storage Tank is one of several 210-gallon options, and the choice is mostly about footprint versus stability.
Tall vertical vs. squat or horizontal: This tank's slender 32-inch base is its advantage where floor space is tight, but its 67-inch height raises the center of gravity and demands a dead-level base. A wider, shorter tank of similar volume is more stable and easier to fill but eats more floor; a horizontal leg tank rides lower and steadier on a trailer or sprayer. Choose the tall vertical for a fixed, space-constrained spot.
Vertical vs. cone-bottom: For storing and drawing chemical, this flat-bottom vertical is simpler and cheaper. If your job is batch mixing that needs a complete drain every cycle, a cone-bottom tank on a stand is the right tool. Buy the vertical for storage, the cone for processing.

Frequently Asked Questions
How long will the 210 Gallon Vertical Liquid Storage Tank last?
With compatible chemistries on a level base and reasonable UV protection, this seamless poly shell readily reaches 15-plus years. On a chemical tank the chemistry and sun exposure, not age, set the pace — an aggressive product can craze the wall and constant field sun chalks the surface. Keep contents within the 1.5 specific-gravity rating, decontaminate between products, watch the high-load lower wall, and shade the tank in intense UV to reach the long end of its life.
What chemicals can I store in this tank?
This is a chemical and liquid storage tank rated to 1.5 specific gravity, built to hold agricultural and industrial solutions up to 12.5 pounds per gallon — liquid fertilizers, herbicides, pesticides, and water-based cleaning chemistries. It is not intended for drinking water, and never for gasoline, diesel, solvents, or flammables. Polyethylene resists most acids and bases but is attacked by certain hydrocarbons and oxidizers, so confirm any new product against a compatibility chart first.
What kind of foundation does a 210-gallon tank need?
A firm, level surface sized for the load and the height. A full 210-gallon charge at 1.5 specific gravity is roughly 2,686 pounds, and the tall column concentrates that on a 32-inch base — a level concrete pad that carries the dead load without settling is the right foundation. Flatness matters extra here: an uneven base both over-stresses the wall and tips a tank that stands taller than it is wide.
Does this tank come with a warranty?
Yes — Norwesco provides a 3-year warranty against defects in materials and workmanship for tanks used within their rated limits, covering molding faults such as voids and pinholes. It does not cover chemical attack from an incompatible product, damage from exceeding the 1.5 specific-gravity rating, improper installation, or impact. Keep your invoice and a photo of the installed tank for any claim.
Can I install this tank underground?
No. This is an above-ground vertical tank; its wall is not engineered to resist the hydrostatic pressure of surrounding soil, and a tall tank buried would be especially prone to collapse. Burial voids the warranty. For below-grade storage, use a purpose-built underground tank designed with ribbed, reinforced walls to handle backfill and groundwater loads.
Buying Considerations
Before ordering the 210 Gallon Vertical Liquid Storage Tank, confirm three things. First, the space — the slender 32-inch footprint fits tight spots, but verify you have the overhead for a 67-inch tank and a dead-level base for its higher center of gravity. Second, compatibility and base — the roughly 2,686-pound full charge needs a level concrete pad, and your valves, gaskets, and hose must suit the chemistry within the 1.5 specific-gravity rating; this is a chemical tank, not a water vessel. Third, freight — at 59 pounds empty it ships LTL on a pallet, so request a liftgate if you lack a dock or forklift.
