This is the space-saver of the 1,500-gallon class: a tall, slim Norwesco column standing 116 inches high on a 64-inch base, packing serious volume into barely 22 square feet of floor. The 1.5-specific-gravity wall is rated for fertilizers and industrial chemicals up to 12.5 pounds per gallon.

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 1500 Gallon Vertical Liquid Storage Tank in this 116-inch-tall configuration is the answer when you need 1,500 gallons but the ground you have is precious. Nearly ten feet of height on a five-foot-plus base lets it tuck against a wall, fit between structures, or stand in a chemical bay where a wide tank would never go. The trade is overhead: you will fill and inspect through the 16-inch lid from a platform or ladder rather than at eye level.

The tall column also brings a hydraulic advantage. The standing liquid creates a strong head at the outlet, so the tank pushes its contents out under good pressure right down to the last few gallons — useful for gravity feed or priming a pump. Translucent white walls let you track the level through the full height, and the white pigment reflects sun to limit heat gain.

The shell weighs 295 pounds empty. Filled with a 1.5-SG liquid it reaches about 19,060 pounds — close to ten tons stacked over a narrow 22.3-square-foot base, which concentrates load and makes the foundation more demanding than a squat tank's. A 2-inch outlet with a siphon tube sits low for a thorough draw, and the 16-inch lid serves filling and access. No inlet ships installed; add a bulkhead where your plumbing wants one.

It is molded in a single piece with no seam or weld to fail, the UV inhibitor is part of the resin, and Norwesco's 3-year warranty covers manufacturing defects. We inspect every tank again before it ships from our facility.

Installation and Setup Guide

A tall, narrow tank is the configuration that punishes a careless foundation hardest. Ten tons over a small base means high pad pressure, and any tilt is amplified by the height into a real overturning concern. Installing the 1500 well is mostly about a dead-level, load-rated base and proper restraint.

Site Preparation

This tank deserves a level concrete slab sized for the 64-inch base and designed for the loaded weight; a gravel pad must be deeply compacted and confirmed level within a quarter inch across the diameter. On a column this tall, even a slight slope under the base translates to a lean at the top that grows as the tank fills. Strip the area of rock and root before setting it. In high-wind regions, plan tie-downs or a containment ring — an empty 295-pound tank standing nearly ten feet can be moved by a strong gust.

Placement and Connections

Set the tank with the 2-inch siphon outlet toward your pump and keep the run short. Use schedule-80 PVC or stainless, hand-tighten and finish with a strap wrench, and add a flex section before rigid pipe to absorb thermal movement and any slight sway. Because the lid is nearly ten feet up, plan permanent, safe access — a fixed platform or caged ladder — rather than balancing on field equipment.

Venting

Venting protects this slender tank in both directions: a vacuum from a fast draw can crease the tall wall, and over-pressure on a fast fill can stress it. Match the lid vent to your maximum flow rate, and for chemicals that off-gas use a pressure-vacuum relief vent rated for the vapor.

Maintenance and Long-Term Care

The tank itself is low-maintenance; the height just means you should fold the lid and upper-wall checks into whatever safe access you have already built. A quarterly look-over is the whole program.

Quarterly Inspection Checklist

Wall and plumb: Sight up the column to confirm it still stands true; a developing lean signals the base has settled on one side.
Outlet: Check the 2-inch fitting for weeping — the tall liquid head keeps strong, steady pressure on that seal — and snug it by hand.
Foundation: Inspect the slab for cracks or settlement and verify it remains level under the narrow base.
Vent: Clear the lid vent during your top-side access so the tall wall is never starved of air on a fast cycle.

Cleaning

Drain through the siphon outlet, then flush with a rinse that neutralizes the previous chemical from your platform access — the tall, narrow interior is well suited to a top-down spray wand. Follow the manufacturer's decontamination steps and capture the rinse for disposal per its safety data sheet.

UV and Weather Protection

The full ten-foot south face of this tank gathers a lot of sun, so the in-resin UV package works harder here than on a squat tank. Check the sun side annually for chalking, and in extreme-sun climates a shade screen along that wall extends service life.

Alternatives and Comparisons

Within the 1,500-gallon class the choice is footprint versus stability. This tall 64-inch-wide column is purpose-built to save ground and to develop strong outlet head, but it demands a load-rated base and safe high access. A squat 1,500 with a wider base is steadier and easier to reach but eats much more floor. For batch processes needing a complete drain, a cone-bottom tank beats this flat bottom's small residual heel. And for water storage, a water-grade tank costs less since it forgoes the 1.5-SG wall this chemical tank requires.

Frequently Asked Questions

How long will the 1500 Gallon Vertical Liquid Storage Tank - Natural White (64" x 116") #40144 last?

Fifteen to twenty years is a fair expectation when the tank stays at or under 1.5 specific gravity, stands on a level load-rated base, and holds compatible chemistry. The seamless mold and in-resin UV package make the structure durable; what cuts a tank short is an overloaded wall, a vacuum from a clogged vent, a chemical attack, or — particular to a tall tank — an overturning event from a poor base or missing restraint.

What chemicals can I store in this tank?

The 1.5-SG rating covers most liquid fertilizers, ag chemicals, and many acids and bases up to 12.5 pounds per gallon. Polyethylene resists those well, but not strong oxidizers or many solvents, and never flammable fuels. Confirm your exact product on a poly compatibility chart and check its specific gravity before filling.

What kind of foundation does a 1500-gallon tank need?

A full load is roughly 19,060 pounds concentrated over the narrow 64-inch base, so this tall tank really wants a level, load-rated concrete slab. The high pad pressure and the leverage of a ten-foot column make a dead-level surface essential — flat within a quarter inch — and in windy areas plan tie-downs as well.

Does this tank come with a warranty?

Yes, three years from Norwesco against defects in materials and workmanship — pinholes, molding flaws, and factory fitting defects. It excludes overloading past 1.5 SG, chemical incompatibility, a faulty foundation, and impact or overturning damage. Save the receipt and a few photos of the finished installation for any claim.

Can I install this tank underground?

No. This is an above-ground vertical tank; its flat walls cannot resist burial pressure and would collapse, voiding the warranty. For underground storage choose a ribbed, reinforced cistern engineered for soil and groundwater loads.

Buying Considerations

Three checks before ordering. First, the height: this tank needs nearly ten feet of clearance and safe access to a lid that sits at the top of a ten-foot column — confirm both. Second, the foundation — ten tons on a narrow base calls for a level, load-rated slab and, in wind country, tie-downs. Third, the liquid and freight — stay at or under 1.5 specific gravity, and expect LTL delivery requiring a forklift to set this tall unit. Call us to plan the install and delivery.
