1000 Gallon Vertical Liquid Storage Tank - Natural White (64" x 80"): Complete Buyer's Guide
The 1,000-gallon mark is where a chemical program goes from incidental to operational, and this Norwesco upright hits it in a balanced 80-by-64-inch package — tall enough to save floor, stout enough to stand steady. Its 1.5-specific-gravity wall is rated for fertilizers and ag chemicals 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 1000 Gallon Vertical Liquid Storage Tank is one of the most popular sizes Norwesco builds, and this configuration shows why: at 80 inches tall on a 64-inch base it splits the difference between footprint and stability, fitting most chemical bays and ag yards without either eating the floor or towering overhead. The 16-inch lid sits a short reach above head height for filling and sampling.
The proportions are practical rather than extreme. A 64-inch base over 22.3 square feet keeps the loaded mass reasonably planted, while the 80-inch height gives the outlet a solid head for feeding a pump. Translucent white walls let you read the chemical line through the shell, and the white pigment reflects sun to hold the contents cooler in the open.
The empty shell is 175 pounds. Filled with a 1.5-SG liquid the tank reaches about 12,685 pounds — a bit over six tons that the base must carry on its moderate footprint. A 2-inch NPT outlet is installed at the bottom, and the 16-inch lid covers filling and interior access. No inlet ships from the factory; fill through the lid or add a bulkhead where your plumbing wants it.
The tank is molded in one piece — no seam, no weld, no leak path — with UV stabilizer compounded into the resin and Norwesco's 3-year defect warranty behind it. We inspect each tank again before it ships.

Installation and Setup Guide
The balanced shape of the 1000 makes it straightforward to install, but six tons of full load still demands a proper base and tidy plumbing. Treat the foundation seriously and this tank disappears into the background of your operation for years.
Site Preparation
Give it a firm, level base that fully supports the 64-inch diameter — a 4-inch compacted gravel pad or a concrete slab both work at this weight. Level it within a quarter inch across the base; a tilt under a tank of this height grows into a lean as it fills. Clear rocks and roots before placing, since the flat bottom presses straight down on the surface.
Placement and Connections
Set the 2-inch outlet toward your pump and keep the run short. Use schedule-80 PVC or stainless bulkhead fittings, tighten by hand and finish with a strap wrench, and add a flex coupling before rigid pipe so the tank can move with temperature without straining the connection. Leave about two feet of clearance for sampling and inspection.
Venting
A 1,000-gallon tank can be pulled into vacuum by a brisk pump if the vent is undersized. Size the lid vent to your fastest draw so air keeps pace with the liquid, and on chemical duty use a pressure-vacuum relief vent rated for the product's vapor.
Maintenance and Long-Term Care
Upkeep is minimal — a quarterly walk-around is the whole of it, and it pays for itself by catching small problems early.
Quarterly Inspection Checklist
- Wall: Look for any bulge or a flat spot at the base; either suggests an overloaded wall or a settled pad.
- Outlet: Check the 2-inch fitting for weeping and snug it by hand as the poly relaxes around it under head pressure.
- Foundation: Verify the pad is still level and that water drains away from the base.
- Vent: Keep the lid vent clear of debris and crust so the tank breathes freely on every cycle.
Cleaning
Drain through the 2-inch outlet, then flush the interior with a rinse that neutralizes the previous chemical before changing products. Clean from above through the 16-inch lid with a spray wand rather than entering. Catch the rinse water and handle its disposal per the product's SDS.
UV and Weather Protection
The resin UV package handles years of exposure, but the south wall ages first. Inspect that face once a year for chalk or fading, and in extreme sun a shade panel on that side extends the shell's life.
Alternatives and Comparisons
The 1,000-gallon class is the catalog's bread and butter, so the alternatives are mostly about shape and service. This balanced upright is the all-rounder. Need to save floor? A taller 1,000 narrows the base further at the cost of height. Want maximum stability on rough or windy ground? A squat 1,100 with a wider base sits lower. For batch work that must drain completely, a cone-bottom tank beats this flat bottom's small heel. And for water rather than chemistry, a water-grade 1,000 costs less by skipping the heavier 1.5-SG wall this tank carries.
Frequently Asked Questions
How long will the 1000 Gallon Vertical Liquid Storage Tank - Natural White (64" x 80") last?
Plan on fifteen to twenty years when the tank stays at or under 1.5 specific gravity, sits on a level base, and holds compatible chemistry. The one-piece shell has no joints to fatigue and the UV protection is in the resin. The usual culprits behind an early failure are a too-heavy liquid, a clogged vent that pulled a vacuum, or a chemical that attacked the polyethylene.
What chemicals can I store in this tank?
At 1.5 SG it handles most liquid fertilizers, ag chemicals, and many acids and bases up to 12.5 pounds per gallon. Polyethylene handles those well but is no match for strong oxidizers or many solvents, and flammable fuels are off the table. Run your specific product past a polyethylene compatibility chart and confirm its specific gravity before the first fill.
What kind of foundation does a 1000-gallon tank need?
A full load is about 12,685 pounds on the 64-inch base. A 4-inch compacted gravel pad or a level concrete slab sized to the diameter handles it. Keep the surface flat within a quarter inch and clear of rock under the bottom — the controlling factor is levelness, not exotic foundation work.
Does this tank come with a warranty?
Yes — Norwesco covers it for three years against material and workmanship defects: molding flaws, pinholes, and faulty factory fittings. Overloading past 1.5 SG, chemical attack, a poor foundation, and impact damage are not covered. Hold on to your receipt and a couple of photos of the finished setup for any future claim.
Can I install this tank underground?
No. This is an above-ground tank; its flat walls cannot take burial pressure and would collapse, voiding the warranty. For below-grade storage use a ribbed, reinforced underground cistern built for soil and groundwater loads.
Buying Considerations
Three checks before ordering this 1,000-gallon tank. First, the footprint — at 80 by 64 inches it fits most bays and pads, but confirm both the height clearance and step access to the lid. Second, the liquid: stay at or under 1.5 specific gravity and verify the weight. Third, freight — it ships LTL on a pallet and wants a forklift or lift gate to unload. Call us and we will arrange delivery to your site.
