1295 Gallon Vertical Liquid Storage Tank: Complete Buyer's Guide
The 1,295-gallon vertical is a short, wide tank — 64 inches tall on an 84-inch base — built for stability and easy access over height. With a 1.5 specific-gravity wall and a 2-inch outlet, it's a low-profile chemical and fertilizer tank for sites with limited overhead clearance.
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 defining feature of the 1,295-gallon is how low it sits. At just 64 inches tall on a seven-foot-wide base, it stores nearly thirteen hundred gallons under five and a half feet of height — low enough to fit under a barn loft, a low eave, a carport, or any structure where a taller tank simply wouldn't clear. That low-profile geometry is the whole reason to choose it over a taller tank of similar volume.
It's rotomolded by Norwesco as a single seamless piece of virgin linear polyethylene, rated to a 1.5 specific gravity, so the wall handles liquids up to 12.5 pounds per gallon — the dense ag chemicals, liquid fertilizers, and treatment solutions a tank this size holds. The short liquid column is an engineering advantage: with only about five feet of head, the hydrostatic pressure at the base is modest compared to a tall tank of the same capacity, and the wide footprint distributes the weight broadly. The result is a stable, foundation-friendly tank that's hard to tip and easy on its pad.
Empty weight is 250 pounds. Filled with a 1.5-SG product it loads the pad with roughly 16,450 pounds, eight-plus tons spread across the 84-inch base, which keeps the pressure per square inch reasonable. The translucent natural-white wall lets you read the level at a glance — and because the lid sits low, both filling and inspection are far more accessible than on a tall tank. Maximum service temperature is 120°F, with UV stabilizers compounded into the resin for outdoor duty.
The outlet is a 2-inch NPT fitting, factory-installed and leak-tested. The 16-inch lid handles fill, vent, and inspection — and at this low height you can reach it from a short step rather than a platform. Norwesco's 3-year warranty applies, and the tank ships LTL freight on a pallet with liftgate available for sites without a dock.

Installation and Setup Guide
The low-profile geometry makes the 1,295-gallon one of the easier large tanks to install: low center of gravity, broad load distribution, and a lid you can actually reach. The foundation still matters, but the tank's proportions are working in your favor.
Site Preparation
Build a flat, level pad under the full 84-inch footprint — a substantial compacted-gravel bed or, better for eight-plus tons, a concrete slab. Level within an inch across the diameter. The wide base spreads the load and the short column keeps pressure modest, so the foundation is less demanding than a tall tank's — but it must still be continuous and non-settling under the entire base. Clear rock and debris, and grade for drainage away from the pad.
Placement and Connections
Position the 2-inch outlet for the shortest run to your pump. With a low tank the available gravity head is small, so if you're relying on gravity feed rather than a pump, account for the limited pressure the short column provides — this is the tradeoff for the low profile. Fit a flexible coupling at the bulkhead to absorb the tank's thermal flex; even a stable wide tank breathes, and a rigid line will work the fitting loose. Match valve and fitting materials to the stored chemical.
Venting
Provide a vent in the 16-inch lid matched to your draw rate through the 2-inch outlet. A wide low tank is more resistant to dramatic collapse than a slender one, but it can still dimple or distort under vacuum if it can't breathe during a fast draw. For off-gassing chemistry, use a pressure/vacuum relief vent rated to the vapor.
Maintenance and Long-Term Care
A low-profile tank is genuinely easy to maintain — the accessible lid and broad stable base remove most of the hazards that complicate tall-tank inspections. The focus is settlement under the wide base and the usual chemical-service hygiene.
Quarterly Inspection Checklist
- Base and settlement: Walk the 84-inch perimeter and check that the wide base sits evenly with no low edge or gap. Differential settlement is the main structural concern for a broad heavy tank.
- Wall: Scan for any bulge or change in translucency. The modest liquid head means lower-wall stress is relatively low, but a denser-than-rated product or an uneven base can still show up here.
- Outlet: Check the 2-inch fitting for weeping or dried residue; hand-tighten only.
- Vent and lid: The low lid makes this easy — confirm the vent is clear and the lid seals. Take advantage of the easy access to actually look inside.
Cleaning and Changeover
The accessible 16-inch lid is a real benefit at cleaning time — you can reach the floor and lower wall easily to clear settled solids. Drain, then flush per the outgoing chemical's procedure before switching products; even at thirteen hundred gallons, residue can react with or contaminate the next load. Confirm polyethylene compatibility with the incoming chemistry before refilling, and handle rinsate per the label.
UV and Heat
The wide low body presents a large top surface and a shorter side wall to the sun. Inspect exposed surfaces yearly for chalking. The low profile often makes shading practical — a simple lean-to or the structure it's already tucked under does the job — which extends service life in a hard-UV climate.
Alternatives and Comparisons
Thirteen hundred gallons can be stored tall or short, and this tank is firmly the short option:
Low-profile versus a taller 1,000-to-1,300-gallon tank: this wide body wins decisively where overhead clearance is the constraint — it fits under structures a taller tank can't — and it's more stable and easier to access. The tradeoff is floor space and gravity head: a tall tank of similar volume uses less floor and provides more outlet pressure from its taller column. Choose by which constraint dominates your site.
Pumped versus gravity feed: because the short column offers limited gravity head, this tank pairs best with a transfer pump. If you specifically need gravity pressure, a taller tank serves better.
Frequently Asked Questions
How long will the 1295 Gallon Vertical Liquid Storage Tank last?
Fifteen to twenty years is realistic with a level base and use within the 1.5-SG and 120°F ratings. The low-profile geometry actually helps longevity — low stress, stable stance, easy inspection — so foundation quality and chemical compatibility are what determine reaching the upper end of the range.
What chemicals can I store in this tank?
The 1.5-SG rating covers ag chemicals, liquid fertilizers, herbicides, pesticides, and industrial and treatment solutions up to 12.5 pounds per gallon. Not for fuels, solvents, or flammables. Verify the specific product on a compatibility chart — polyethylene resists most acids and bases but is attacked by certain hydrocarbons and strong oxidizers.
What kind of foundation does a 1295-gallon tank need?
Plan for roughly 16,450 pounds full, distributed across the 84-inch base. A heavy compacted-gravel pad works, but a concrete slab is better for eight-plus tons; either way it must be level within an inch and continuous under the whole base. The wide footprint and short column make the foundation less demanding than a tall tank's, but it still must not settle unevenly.
Does this tank come with a warranty?
Yes — Norwesco's 3-year warranty covers factory material and workmanship defects. It excludes over-spec products, uneven or improper installation, incompatible-chemical attack, and impact damage. Keep your receipt and a record of the level install.
Can I install this tank underground?
No — this is an above-ground vertical not engineered for burial; surrounding soil would deform the wall. For below-grade storage, use a purpose-built underground cistern designed for soil load.
Buying Considerations
The 1,295-gallon's pitch is simple: maximum capacity under minimum height. Before ordering, confirm the low profile is actually what you need — if overhead clearance is tight, this tank's 64-inch height is its killer feature; if you have height and need floor space or gravity pressure, a taller tank serves better. Verify your product is at or under 1.5 SG, and provide a level pad for eight-plus tons across the wide base. Ships LTL on a pallet; request a liftgate if you're unloading without a dock or forklift.
