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 5,000-gallon vertical liquid tank is bulk agricultural and industrial chemical storage at fleet-and-co-op scale. Norwesco molds it as a broad, low cylinder — 141 inches across and just 86 inches tall — a deliberately squat shape that keeps a thirty-one-ton full load close to the ground and stable, and lets the tank live under a roofline a taller 5,000 could never clear. Empty it weighs 855 pounds.
The seamless shell is rotomolded from virgin linear polyethylene rated to 1.5 specific gravity, carrying dense liquids up to 12.5 pounds per gallon. Translucent natural-white walls let you gauge a five-thousand-gallon level at a glance and reflect sunlight to moderate the temperature of the contents, and the resin is FDA-compliant for food-grade service.
Full at the rated gravity the tank loads its foundation with about 63,405 pounds, which puts an engineered, reinforced slab squarely on the critical path. The outlet is generous and flexible — a 3-inch fitting with a 2-inch reducer and a 3-inch siphon tube — factory-installed and leak-tested for high-flow transfer or metered draw. The 16-inch lid opens the top for inspection. Norwesco's 3-year warranty applies.

Installation and Setup Guide
At 5,000 gallons of chemistry, installation is an engineering project with a containment dimension. Thirty-one tons across a 141-inch circle is designed for, never improvised, and the consequences of a release at this volume make secondary containment a serious consideration.
Site Preparation
This tank requires a reinforced concrete pad at least six inches thick, engineered by a qualified professional for the full 63,405-pound load and finished flat to within a quarter inch across the entire 141-inch base — on a footprint this broad even a slight slope drives tons onto one arc of the wall. Where the chemical warrants it, integrate containment sized to the tank's volume into the slab design. Site it for tanker and fill-line access.
Placement and Connections
Allow at least three feet of clearance to walk the whole shell and work the fittings. Run the 3-inch outlet to your pump by the shortest route, using the reducer where your line is smaller, and connect through chemical-rated flexible couplings — a thirty-one-ton tank moves enough through its thermal and fill cycles to destroy a rigid joint. Spec every gasket and valve to the chemistry.
Venting
On this volume the vent is a safety system. A high-flow transfer can pull a severe vacuum and a fast fill can build real pressure, so size the vent generously to your peak flow, and where the chemical off-gasses, use a pressure/vacuum relief vent rated for that chemistry so the broad top deck neither sucks down nor domes.
Maintenance and Long-Term Care
A 5,000-gallon chemical tank earns a thorough routine; the volume magnifies any neglected problem, and the chemistry adds compatibility and containment to the watch list.
Quarterly Inspection Checklist
- Full-shell walk: circle the entire 141-inch tank for bulging, stress whitening, or weeping. The lower band carries enormous hoop stress — distortion there stops the inspection until you understand it.
- Fittings and seals: inspect the 3-inch outlet, reducer, and every gasket for chemical attack; hand-snug only, no wrench on poly threads.
- Slab and containment: check the engineered pad for cracking or settling and confirm any containment is intact and drained of rainwater.
- Vent: confirm the relief vent is open and functioning — on this volume a blocked vent deforms the deck in a single transfer.
Cleaning and Chemical Changeover
Decontaminate strictly per the chemical manufacturer's protocol before any changeover — at 5,000 gallons the volume of residue and rinsate is significant and must be captured and disposed of per label and regulation. Triple-rinse with a compatible solution, and verify the incoming chemical against both the polyethylene and every seal before refilling. Treat interior entry as confined-space work: never enter alone, and ventilate and test the atmosphere first.
UV and Weather Protection
The reflective white wall runs cooler than a dark tank but transmits some light, which can feed algae in a water-based solution or age light-sensitive chemistry. The large wall area makes a permanent shade structure worth considering in intense sun, both for service life and to keep a big volume of contents stable.
Alternatives and Comparisons
At 5,000 gallons the choice is footprint and bottom shape. This broad flat-bottom vertical is the efficient bulk-storage and transfer option; where your process needs complete drainage and self-cleaning, a large cone-bottom drains through its apex but stands much taller and needs a heavy stand. For a tighter site, the 4,200 in a narrower 102-inch profile holds nearly as much; for greater bulk, larger verticals follow.

Frequently Asked Questions
How long will the 5000 Gallon Vertical Liquid Storage Tank - Natural White (141" x 86") last?
With compatible chemistry, a proper engineered slab, and use within its 1.5 SG and 120 F limits, 15 to 20 years and beyond is realistic. At this scale the foundation and the chemical compatibility dominate longevity — get both right and the seamless shell reaches the far end of that range.
What chemicals can I store in this tank?
Rated to 1.5 specific gravity, it holds agricultural chemicals, fertilizers, and industrial solutions within that density, and the resin is FDA-compliant for food-grade liquids. No fuels, solvents, or flammables, and beware oxidizers and certain hydrocarbons that attack polyethylene. Verify the specific chemical, its concentration, and your seal materials before filling.
What kind of foundation does a 5000-gallon tank need?
Full it weighs about 63,405 pounds — over thirty-one tons — so it needs an engineered, reinforced concrete slab at least six inches thick, level across the 141-inch base. A gravel pad is not adequate. Build in secondary containment where the chemistry requires it.
Does this tank come with a warranty?
Three years of Norwesco coverage applies to manufacturing and fitting defects present from the factory. Overloading, an inadequate foundation, chemical attack, and impact are excluded. Keep full records and slab engineering given the investment.
Can I install this tank underground?
No. Burying a 5,000-gallon vertical shell guarantees collapse under soil pressure and voids the warranty. Below-grade chemical storage at this volume requires purpose-engineered underground tankage with containment.
Buying Considerations
Three prerequisites for a clean 5,000-gallon install. First, the foundation: an engineered, reinforced slab poured before the tank ships, with containment if the chemistry demands it. Second, compatibility: confirm your chemical and concentration against the polyethylene and every seal and valve. Third, the freight — this tank moves by dedicated oversize carrier and needs crane or heavy-forklift access to set. Call us early to coordinate carrier, unload, slab, and containment together.
