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 1,550 Gallon Vertical Liquid Storage Tank in natural white is a mainstay of the agricultural chemical and fertilizer yard — the size at which a sprayer-fill operation stops running back to the supplier and starts working from its own bulk supply. At 87 inches across and only 67 inches tall, it is a notably squat, wide tank, which keeps it stable and easy to fill without a tall fill platform.
Norwesco rotationally molds the body in one seamless piece of virgin linear polyethylene rated to 1.5 specific gravity, covering liquid fertilizers, crop-protection chemistry, and most industrial solutions up to 12.5 pounds per gallon. The translucent natural-white wall lets an operator read the level from across the yard and reflects sunlight to keep the contents cooler, with UV inhibitors compounded into the resin and a 120 F / 48 C service ceiling.
Empty, the tank weighs 220 pounds; full at 1.5 SG it bears down at roughly 19,610 pounds, so it needs a substantial, level foundation. A factory 2-inch NPT fitting with an integral 2-inch siphon tube draws the tank down to the bottom, and the 16-inch lid opens for filling, venting, and dropping in instrumentation. Every tank is inspected on the production floor and again before it ships from us.

Installation and Setup Guide
A wide, low tank like this 1,550-gallon vessel is forgiving to fill and stable in wind, but its broad 87-inch base means you have a large circle of ground that must be brought truly flat. Roughly 19,610 pounds of chemical sit on that base when the tank is full, and the load wants to press straight down across the whole footprint.
The Foundation
For agricultural chemical service, set this tank on a reinforced concrete slab or a deep, well-compacted aggregate pad sized for nearly ten tons and leveled across the full diameter. A slab also doubles as the floor of a containment area, which matters for chemical storage — many fertilizer and crop-protection liquids must be kept over secondary containment. Grade the surroundings so any spill or rainwater is directed, not pooled.
Plumbing for Chemical Duty
The 2-inch fitting with its built-in siphon pulls product from the bottom, ideal for transferring to a sprayer or a metering pump. Plumb it in schedule 80 PVC or stainless rated for your chemistry, keep the first foot flexible to absorb the wall's thermal movement, and fit a full-port chemical-rated valve. Avoid mixing metals that your product can attack, and support every line independently of the tank fitting.
Venting for Vapors
Many stored chemicals off-gas, so do not rely on a plain breather. Fit a pressure/vacuum relief vent in the 16-inch lid rated for the specific product, sized so the tank neither pulls a vacuum on a fast draw nor pressurizes on a fast fill. Proper chemical venting protects both the tank and the operator.
Maintenance and Long-Term Care
This is chemical-storage equipment, and its maintenance is about containment integrity and chemical compatibility — not the potable-water routine. Every inspection asks two questions: is the tank sound under load, and is the chemistry doing anything to it.
Quarterly Chemical-Service Checks
- Wall and seams: Backlight the translucent white wall and look for bulging, stress whitening, or any change in the resin where it contacts the product. Polyethylene can swell or craze if a borderline-compatible chemical attacks it; catch that early.
- Fittings and siphon: Inspect the 2-inch fitting, siphon, and valve for weeping or chemical etching, and hand-snug threads that have crept. Replace any gasket the product has degraded.
- Vent: Confirm the pressure/vacuum vent is clear and functioning — a fouled chemical vent is both a deformation risk and a vapor hazard.
Changing Chemistries
Before switching products, drain completely, then decontaminate following the incoming chemical manufacturer's procedure and confirm the new product against a polyethylene compatibility chart. Never assume two agricultural chemicals are mutually safe in the same residual film. This tank carries no food or drinking-water role, so cleaning is strictly about compatibility and cross-contamination control.
UV and Weather
The compounded UV package protects the white wall outdoors; in high-sun regions inspect the sun-facing side yearly for chalking. The reflective white also helps keep volatile products cooler and reduces vapor pressure inside the tank during summer heat.
Alternatives and Comparisons
At 1,550 gallons the choice is largely about proportions, and this tank is built deliberately low and wide.
Low-and-wide vs. tall-and-narrow: This 67-inch-tall, 87-inch-wide tank stays stable, fills easily without a high platform, and presents a low profile in the yard — useful where wind or sightlines matter. A taller 1,550-gallon vertical claims less ground and gives a stronger gravity head for feeding a sprayer by elevation, at the cost of needing a fill ladder and being more exposed. For chemical service over containment, the wide tank's stability and easy access often win; where pad space is tight, the tall tank fits better.

Frequently Asked Questions
How long will the 1550 Gallon Vertical Liquid Storage Tank - Natural White (87" x 67") #42595 last?
On a sound, level foundation and within its 1.5 SG and 120 F ratings, this tank typically delivers 15 to 20 years in chemical service. The compounded UV package shields the resin from sun and the seamless body has no weld to fail. What shortens that span is storing a chemical outside the polyethylene compatibility window, exceeding the rated density, or an uneven pad — not the tank itself when used as intended.
What chemicals can I store in this tank?
It is rated to 1.5 specific gravity and handles most liquid fertilizers, crop-protection chemicals, and industrial solutions up to 12.5 pounds per gallon. Always confirm a specific product on a polyethylene compatibility chart first, since polyethylene resists many acids and bases but can be attacked by certain solvents and strong oxidizers. It is not for fuels or flammables. This is a chemical-storage tank, not a potable-water vessel.
What kind of foundation does a 1550-gallon tank need?
A full 1,550-gallon tank at 1.5 SG weighs about 19,610 pounds — close to ten tons. That calls for a reinforced concrete slab or a deep, well-compacted pad, level across the full diameter. For chemical service the slab ideally serves as secondary containment as well. An uneven foundation is the leading cause of premature poly-tank failure.
Does this tank come with a warranty?
Norwesco backs this tank against defects in materials and workmanship under normal use — molded-in faults such as pinholes, cracks, and fitting defects. It does not cover damage from incompatible chemicals, exceeding the rated specific gravity, a poor foundation, or impact. Contact us for the specific warranty terms on this model, and keep your receipt and installation photos.
Can I install this tank underground?
No. This vertical tank is engineered for above-ground service and its walls cannot resist soil pressure; burying it would risk collapse and void coverage. For below-grade storage, our underground cisterns and septic products are reinforced specifically for burial loads.
Buying Considerations
Three things to verify before this 1,550-gallon liquid tank ships. First, the pad: a level slab or deep compacted base over seven feet across, ideally serving as containment for chemical duty and sized for nearly ten tons full. Second, your chemistry, confirmed against a polyethylene compatibility chart, since the 1.5 SG rating covers most but not all agricultural and industrial liquids. Third, freight — a tank this size ships oversized and needs a forklift to set, not a curbside drop. Listed at $1,638.00 before freight, with delivery quoted to your ZIP.
