Storing 6,000 gallons in just over fifteen feet of height, this Norwesco vertical trades a wider footprint for sheer vertical reach — 182 inches tall on a 102-inch base, with a 3-inch siphon outlet for high-volume transfer. Rated to 1.5 specific gravity, the wall handles 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 6000 Gallon Vertical Liquid Storage Tank is the tall sibling among large-volume tanks: where a 6,500 spreads out on a broad base, this one reaches up, packing 6,000 gallons into a 102-inch footprint by standing a towering 182 inches — over fifteen feet. It is the choice when bulk storage must fit a footprint the bigger-diameter tanks would overrun.

That height has consequences in both directions. It gives the outlet a powerful standing head for transfer and gravity feed, and it minimizes ground area. But it also concentrates an enormous load on a relatively narrow base and puts the lid more than fifteen feet up. The outlet is a 3-inch fitting with a 2-inch reducer and a 3-inch siphon tube to move the volume; translucent white walls allow level reading along the full height and reflect heat.

Empty, the tank weighs 1,275 pounds. Filled with a 1.5-SG liquid it reaches about 76,335 pounds — over thirty-eight tons on 56.7 square feet, a high pad pressure that absolutely requires an engineered foundation. The 16-inch lid serves top access. The factory ships no inlet; add a bulkhead to fit your plumbing.

It is molded seamlessly despite its height, with UV stabilizer in the resin and Norwesco's 3-year defect warranty. Its dimensions require dedicated freight and planned site access, which we coordinate with you.

Installation and Setup Guide

A fifteen-foot tank holding thirty-eight tons is the most demanding combination in this catalog: maximum height leverage on a high-pressure base. The foundation must be engineered, and the access and restraint planned, before this tank ever ships.

Site Preparation

This tank requires a reinforced concrete foundation, designed by a structural engineer for the full 76,335-pound load and the high pad pressure of the 102-inch base, with attention to your soil conditions. The slab must be flat across the diameter within a tight tolerance — at fifteen feet of height, the smallest tilt becomes a significant lean and an uneven load on the lower wall. Plan the pad, truck access, and heavy lifting equipment together; setting a tank this tall is a rigging operation.

Placement and Connections

Position the tank with the 3-inch siphon outlet facing your transfer system and the run short. Use schedule-80 PVC or stainless on the bulkhead, hand-tighten with a strap-wrench finish, and add a flexible section before rigid pipe to absorb the considerable thermal movement and any sway of the tall column. Build permanent, caged access to the lid fifteen feet up, and consider restraint appropriate to wind exposure.

Venting

High-volume transfer through a 3-inch line moves huge air volumes, and a tall slender wall is especially prone to vacuum creasing. Provide a large vent matched to your maximum flow rate, and for any off-gassing chemical use a pressure-vacuum relief vent rated for the product.

Maintenance and Long-Term Care

This tank's value and height both argue for disciplined, scheduled inspection using the permanent access you have built.

Quarterly Inspection Checklist

Plumb and lower wall: Sight up the fifteen-foot column for any lean, and inspect the high-stress base ring for bulging or distortion against the slab.
Outlet: Check the 3-inch fitting and siphon for weeping under the very strong head this height produces.
Foundation: Examine the engineered slab for cracking or settlement under the concentrated load.
Vent: Confirm the large vent is fully clear; a vacuum on this slender wall develops a crease quickly.

Cleaning

Drain fully through the 3-inch siphon outlet, then flush from your top access with a rinse that neutralizes the previous chemical. Follow the manufacturer's decontamination procedure and handle the large rinse volume per its safety data sheet as a planned operation.

UV and Weather Protection

A fifteen-foot south wall takes a heavy annual sun load, so check it for chalking each year. In severe-sun climates, protecting this tall, costly shell with shade on the sunny side is worthwhile.

Alternatives and Comparisons

The 6,000-gallon decision is height versus footprint. This tall tank is the ground-saver, ideal where floor area is tight and overhead is available, and it builds strong outlet head. A wider 6,500 spreads the load over more area, lowering pad pressure and easing access at the cost of footprint. Multiple smaller tanks give redundancy and serviceability. For batch work needing a full drain, a large cone-bottom on a stand is the right tool. And for bulk water, a water-grade tank costs less by carrying a lighter 1.1-SG wall than this 1.5-SG chemical build.

Frequently Asked Questions

How long will the 6000 Gallon Vertical Liquid Storage Tank last?

With an engineered foundation, operation within the 1.5 specific-gravity rating, and compatible chemistry, fifteen to twenty years is a sound expectation. The seamless shell and in-resin UV package make the vessel durable; the failure modes to guard against are an overloaded or vacuum-creased wall, a chemical attack, and a foundation or restraint inadequate for a fifteen-foot, thirty-eight-ton tank.

What chemicals can I store in this tank?

The 1.5-SG wall handles the bulk of liquid fertilizers, ag chemicals, and many industrial acids and bases at or under 12.5 pounds per gallon. Polyethylene is highly resistant to those, though strong oxidizers and many solvents will degrade it and flammables are prohibited. Confirm your product on a poly compatibility chart and verify its specific gravity before filling.

What kind of foundation does a 6000-gallon tank need?

A full load is roughly 76,335 pounds over the 102-inch base, producing high pad pressure that requires a reinforced concrete foundation engineered by a structural professional. At fifteen feet of height, the slab must be dead-level across the diameter, and wind restraint should be evaluated for your site.

Does this tank come with a warranty?

Yes, Norwesco warrants it three years against manufacturing defects including molding flaws and pinholes. It excludes overloading past 1.5 SG, chemical attack, an inadequate or non-engineered foundation, and impact or overturning damage. Retain your invoice and installation records for any claim.

Can I install this tank underground?

No. It is an above-ground vertical tank whose flat walls would collapse under burial pressure. For below-grade storage, use vessels engineered with ribbed, reinforced walls for soil and groundwater loads.

Buying Considerations

Plan three things before ordering this tall, large tank. First, the foundation — thirty-eight tons at high pad pressure requires a professionally engineered reinforced slab specified before delivery. Second, height and access — at over fifteen feet it is a rigging set, ships by dedicated freight, and needs permanent caged lid access. Third, weigh the liquid: it must be at or under 1.5 specific gravity, so verify its density. Call us early to coordinate the delivery, rigging, and site requirements.
