2100 Gallon Vertical Liquid Storage Tank - Natural White (87" x 89"): Complete Buyer's Guide
At 2,100 gallons in an almost perfectly square 89-by-87-inch profile, this Norwesco vertical is the balanced large tank — neither tippy nor floor-hungry — for operations that need real reserve without a towering column. The 1.5-SG wall handles fertilizers and agricultural chemicals weighing up to 12.5 pounds per gallon.
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 2100 Gallon Vertical Liquid Storage Tank lands in the sweet spot between the common 2,000-class tanks and the bigger 2,500. Its near-cubic shape — 89 inches tall on an 87-inch base — keeps the loaded mass low and broad while still standing tall enough to feed a pump with decent head. It is the kind of tank that fits an established ag yard or chemical pad without forcing a redesign of the space.
The balanced proportion is its quiet strength. With the height and width nearly equal, the tank resists tipping and spreads its load over 41.3 square feet, so neither wind nor an uneven hand-off from a forklift threatens it. Translucent white walls reveal the chemical line through the shell and bounce off sun to keep the contents cooler under an open sky.
The empty shell weighs 304 pounds. Filled with a 1.5-SG liquid it reaches about 26,575 pounds — roughly thirteen tons that the base must carry across its broad footprint. A 2-inch NPT outlet is installed at the bottom for draw, and the 16-inch lid handles filling and access. No inlet ships from the factory; add a bulkhead where your plumbing wants one.
The tank is molded in a single piece with no seam or weld, UV stabilizer is part of the resin, and Norwesco's 3-year warranty covers manufacturing defects. We inspect each unit before it ships from our facility.

Installation and Setup Guide
The near-cubic 2100 is one of the more forgiving large tanks to install, but thirteen tons of full load still demands a base sized and leveled for the job. The reward for getting it right is a tank you can largely forget about.
Site Preparation
Provide a base that fully supports the 87-inch diameter — a well-compacted 4-inch gravel pad or a concrete slab both work at this weight. Level it within a quarter inch across the base; even on a balanced tank, a high spot under one edge concentrates load unevenly on the lower wall. Clear rocks and roots before placing so the flat bottom rests on clean, supportive ground.
Placement and Connections
Set the 2-inch outlet toward your pump and keep the plumbing short. Use schedule-80 PVC or stainless bulkhead fittings, hand-tighten with a strap-wrench finish, and add a flex coupling before rigid pipe to absorb the tank's thermal movement. Leave about two feet of clearance for sampling and inspection around the perimeter.
Venting
Filling or drawing 2,100 gallons moves significant air, so size the lid vent to your maximum flow rate to keep air pace with liquid in both directions. For any chemical that off-gasses, fit a pressure-vacuum relief vent rated for the product's vapor.
Maintenance and Long-Term Care
Upkeep is light — a quarterly walk-around catches the few issues that ever arise on a tank this size.
Quarterly Inspection Checklist
- Wall: Scan the sides for any bulge or a flattened patch at the base, both signs of an overloaded wall or settled pad.
- Outlet: Check the 2-inch fitting for weeping and hand-tighten as the poly relaxes under steady head.
- Foundation: Confirm the pad remains level and that runoff drains away from the base.
- Vent: Keep the lid vent clear of dust and crust so the tank breathes on every cycle.
Cleaning
Drain through the 2-inch outlet, then flush the interior with a rinse that neutralizes the previous chemical before switching products. Clean from above through the 16-inch lid with a wand rather than entering. Capture the rinse and route it to disposal as the chemical's SDS directs.
UV and Weather Protection
The resin UV package handles years of exposure; the south wall ages first, so check it annually for chalking or fading. In extreme sun a shade panel on the sunny side extends the shell's service life.
Alternatives and Comparisons
At 2,100 gallons the choice is mostly proportion and process. This near-cubic tank is the steady all-rounder. If you need to save floor, a taller 2,000-class tank narrows the base at the cost of height; if you want maximum stability on rough ground, a squatter wide tank sits lower. For batch work needing a clean drain, a cone-bottom tank beats this flat bottom's residual heel. And for water rather than chemistry, a water-grade tank costs less by skipping the heavier 1.5-SG wall this chemical tank carries.
Frequently Asked Questions
How long will the 2100 Gallon Vertical Liquid Storage Tank - Natural White (87" x 89") last?
Fifteen to twenty years is a fair expectation when the tank stays at or under 1.5 specific gravity, sits on a level base, and holds compatible chemistry. The seamless shell and in-resin UV package make the structure durable; an early failure usually traces to an overloaded wall, a clogged vent that pulled a vacuum, or a chemical the polyethylene cannot resist.
What chemicals can I store in this tank?
At 1.5 SG it suits most liquid fertilizers, ag chemicals, and a broad range of acids and bases up to 12.5 pounds per gallon. Polyethylene stands up to those, yet strong oxidizers, many solvents, and any flammable fuel are out of bounds. Cross-check your chemical on a polyethylene compatibility chart and confirm its weight before charging the tank.
What kind of foundation does a 2100-gallon tank need?
A full load is about 26,575 pounds across the 87-inch base. A well-compacted 4-inch gravel pad or a level concrete slab sized to the diameter handles it. Keep the surface flat within a quarter inch and free of rock under the bottom — levelness is the controlling factor.
Does this tank come with a warranty?
Yes, a three-year Norwesco warranty applies to defects in materials and workmanship, including pinholes and molding or fitting flaws. Overloading past 1.5 SG, chemical attack, a poor foundation, and impact damage are excluded. Save the invoice and a few install snapshots so any claim goes smoothly.
Can I install this tank underground?
No. This is an above-ground tank, and its flat walls would buckle under burial pressure — doing so voids the warranty. For below-grade storage use a ribbed, reinforced underground cistern built for soil loads.
Buying Considerations
Three checks before ordering. First, the near-cubic 89-by-87-inch envelope — confirm both floor space and overhead, since this tank wants a fair amount of each. Second, the contents — keep them at or below 1.5 specific gravity and confirm how much they weigh. Third, freight and foundation — thirteen tons full wants a level load-bearing pad, and the tank ships LTL needing a forklift to set. Call us to plan delivery and talk through your base.
