The Chem-Tainer 1000 Gallon Black Vertical Water Storage Tank is a polyethylene vertical storage tank built for bulk water duty, standing 81 inches tall on a 64 x 64 inch footprint. Black resin blocks sunlight to suppress algae growth, which makes this size a common pick for above-ground water holding, irrigation reserves, rainwater capture, HVAC condensate aggregation, and rural fire-water storage where a fixed reservoir needs to sit outdoors year-round.
Will it hold your water
Filled to its 1000 gallon rating, this vertical storage tank carries roughly 8,340 pounds of contents, so plan the pad accordingly. Water at full volume puts real load on the ground, and a level, fully supported base across the entire 64 x 64 inch footprint is what keeps the tank stable and prevents stress at the bottom knuckle. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm this 1000 gallon vertical water tank fits your space and your daily draw before you commit. The tank is rated to 1.0 specific gravity, which matches water exactly; that rating is the reason it works for water storage and tells you precisely where the line sits for anything heavier.
Watch the specific gravity line
The most common mistake on a water-rated tank is assuming the 1.0 specific gravity rating extends to denser liquids. It does not. This tank is engineered for water at 1.0 SG, and storing a fluid heavier than water exceeds what the wall thickness was designed to carry. If your application is strictly water storage, you are well inside the design envelope. If you need to store something denser than water, call 866-418-1777 and we will route you to an industrial-grade tank built for a higher specific gravity. The pack does not list confirmed fitting sizes for this model, so call the same number to confirm outlet size and lid configuration before you order rather than assuming a particular plumbing layout.
Siting it outdoors and in cold climates
Because this is a black, above-ground tank meant to live outside, two siting questions matter. For reuse setups that aggregate grey-water, rainwater, or HVAC condensate into quality-banded storage, our industrial water reuse tank topology guide walks through how to stage and sequence storage. If you are siting this as a private fire-water reservoir in a freezing climate, the fire-water reservoir design guide covers NFPA-22 sizing discipline and freeze-protection engineering. Cross-check dimensions against the technical drawing on this page before you finalize the pad.
Freight and ordering
This is a large vertical tank that ships LTL on a pallet, with freight quoted live to your ZIP code. It ships from the nearest stocking Chem-Tainer facility to hold freight cost down, so let the Freight Cost Estimator return the real origin and a live LTL quote for your address, or call 866-418-1777 to lock in shipping and confirm lead time. If you are weighing brands before you buy, the Snyder vs Norwesco vs Chem-Tainer vertical tank comparison walks through the tradeoffs, and our general 1000 gallon black water tank buyer's guide covers this class of tank in depth (exact dimensions vary by brand and model, so verify against the specs and drawing shown here).
