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 2500 Gallon Vertical Liquid Storage Tank in its broad 102-inch-diameter form is the low, planted way to store 2500 gallons of chemical or fertilizer. At only 79 inches tall over an eight-and-a-half-foot base, it keeps a heavy chemical load close to the ground, making it a strong choice for sites with height limits, exposed windy locations, or operations that want the easiest possible access to the top.
Cast in a single rotational mold from virgin linear polyethylene and rated to 1.5 specific gravity, it holds dense agricultural and industrial liquids up to 12.5 pounds per gallon. The translucent white wall lets operators gauge the level from the ground and reflects sunlight to keep the stored chemical cooler through the day.
The wide 102-inch base spreads the load over nearly 57 square feet. Empty weight is 370 pounds; filled with a 1.5-SG liquid the foundation carries roughly 31,645 pounds. A factory 2-inch NPT outlet handles discharge and a 16-inch lid opens the top for access; this version is equipped for both fill and discharge so your plumbing connects directly.

Installation and Setup Guide
This 2500-gallon tank is built around its footprint: 79 inches tall on a 102-inch base makes it decisively wider than it is high, so the full 31,645-pound load fans out over nearly 57 square feet at low ground pressure, and the squat profile ignores wind. The geometric trade is familiar — a 102-inch flat bottom is a large mirror for any flaw in the pad, so flatness over that eight-and-a-half-foot span is where the install is won.
Site Preparation
Engineer the foundation to match the diameter and the load. A reinforced concrete slab or deep compacted crushed-stone ring should extend a foot past the 102-inch base and sit flat to a quarter inch across the full width — a demanding tolerance at this scale. With 31,645 pounds bearing down, any high or low spot concentrates tons of load onto a smaller area and fatigues the wall there first; have a structural professional specify the slab.
Placement and Connections
Run the discharge off the factory 2-inch outlet and isolate it with a chemically compatible flexible coupling so the tank's thermal movement never loads the bulkhead; keep the line low and short. Connect your fill line to the inlet provided, using chemical-rated plumbing throughout, and hand-tighten the poly threads a quarter turn past snug rather than reaching for a wrench.
Venting
Even a low, broad tank must breathe with the chemical it cycles. Hold the 16-inch lid's relief path clear, and where the chemistry off-gasses, install a pressure/vacuum relief vent rated to it. A blocked vent on a full chemical tank pulls a vacuum that can dish the wide top inward during a hard draw-down, so verify the vent first and confirm its rating against the stored liquid.
Maintenance and Long-Term Care
A wide, low 2500-gallon chemical tank is one of the easier large verticals to service — the lid and fittings sit within reach and the translucent wall reads the level from the ground. Maintenance follows chemical duty and structural load, with the routine below protecting the vessel and its broad foundation.
Quarterly Inspection Checklist
- Wall sweep: Circle the 102-inch shell and use the translucent wall to catch any low bulge or stress whitening pointing to a settled pad or overweight chemical.
- Fittings check: Inspect both the 2-inch outlet and the inlet for chemical weeping, confirming they remain compatible with the stored liquid.
- Foundation audit: Walk the wide perimeter for settling or washout, since over a 57-square-foot footprint one soft spot quietly carries more than its share.
- Vent verification: Check the pressure/vacuum relief or vent is unobstructed and matched to the chemistry stored.
Cleaning
Clean by decontamination per the chemical manufacturer's procedures whenever you switch products; a rinse alone will not do when changing chemistries. The 2-inch outlet drains the bulk, and the low body keeps the 16-inch lid easy to reach for inspection, with any interior work following confined-space and chemical-handling protocols. This serves as chemical storage and not as a potable-water tank.
UV and Weather Protection
Because the translucent white wall reflects sun and carries resin UV stabilizer, your only yearly task is scanning the sun-facing side for chalking. The reflective pigment is a real asset on a wide outdoor tank, trimming the thermal load the broad surface gathers across a hot day.
Alternatives and Comparisons
This wide 102-by-79 tank is the low, accessible take on 2500 gallons of chemical, where the symmetrical 96-by-96 version balances height and width differently. The 2000-gallon verticals below ease the foundation, while the 3000-gallon-plus tanks above add capacity. This one needs the most ground of the 2500-gallon options but applies the least pressure.
Vertical vs. Horizontal: Vertical tanks use less floor space for the same capacity but require more overhead clearance. If you have height restrictions, consider a horizontal or low-profile tank. Vertical tanks also drain more completely due to gravity — the liquid column above the outlet creates positive pressure all the way to the last few gallons.

Frequently Asked Questions
How long will the 2500 Gallon Vertical Liquid Storage Tank - Natural White (102" x 79") last?
On an engineered pad, within its 1.5 SG and 120°F limits, and serviced for the chemicals it holds, this wide 2500-gallon tank comfortably reaches fifteen years and beyond. The seamless wall has no weld to fail, and the low, broad body makes wind and tipping non-issues; a settling foundation or incompatible chemical is what ends a tank early, never the polyethylene.
What chemicals can I store in this tank?
With a 1.5 specific gravity rating it holds agricultural chemicals, liquid fertilizers, and most industrial solutions to 12.5 pounds per gallon — always verify the chemical on a polyethylene compatibility chart first. No fuels, solvents, or flammables belong in it; keep it solely for chemical storage.
What kind of foundation does a 2500-gallon tank need?
With roughly 31,645 pounds over a 102-inch base, plan an engineered reinforced slab or a deep compacted crushed-stone ring extending past the base and held flat to a quarter inch, specified by a structural professional for your soil.
Does this tank come with a warranty?
Yes — under normal use Norwesco's 3-year warranty covers manufacturing defects: it handles factory faults, not overfilling beyond 1.5 SG, a poor pad, chemical attack, or impact. File away the receipt and your install photos for the record.
Can I install this tank underground?
No. Engineered for above-ground service, the flat wall cannot take soil pressure, so burying it risks collapse and voids the warranty. Below the surface, use a ribbed underground tank designed to handle backfill pressure.
Buying Considerations
Confirm nearly 57 square feet of pad area where you want it, have a structural professional size the slab for the 31,645-pound load over a 102-inch base, and arrange LTL freight with the equipment and access to offload a tank this wide.
