The Chem-Tainer 1000 Gallon Green Vertical Water Storage Tank is a polyethylene vertical storage tank built for bulk water storage where you need real volume in a compact footprint. It stands 81 inches tall on a 64 x 64 inch footprint, so a thousand gallons of water sits on a pad just over five feet square. The green tint cuts light penetration to slow algae growth in outdoor service, which is why it turns up under searches for a vertical water storage tank in the 1000 gallon class.
Key specs: 1000 gallon capacity · height 81" · footprint 64" x 64" · full water weight 8,340 lb · 1.0 specific gravity rating · polyethylene.
Will this tank work for your job?
This is a 1000 gallon vertical water tank with a 1.0 specific gravity rating, meaning it is engineered to hold contents no heavier than water. Filled to capacity, a thousand gallons of water weighs 8,340 pounds, and that is also the maximum rated contents weight, so plan your pad and your water budget around the full 8,340 pound load. The polyethylene wall and the 81 inch height give you a tall, narrow profile that fits tight equipment yards, well houses, and barn corners better than a squat tank of the same volume. Before you commit to a size, run your draw-down and refill numbers through the Tank Sizing Calculator and the Tank Sizing Guide so you are not buying short or buying more tank than the pad can carry. Fitting and outlet configuration is confirmed per unit, so call 866-418-1777 to verify the bulkhead and outlet sizes for your plumbing before you order.
What it is for, and where it fits
At 1000 gallons this water storage tank lands in the size range used for rural fire-water reserves, water reuse trains, and general bulk water storage. If you are sizing a private fire-protection reservoir, the field discipline in our fire-water reservoir design guide walks through reserve sizing and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse topology guide covers how to band tanks by water quality. If you are weighing brands, our Snyder vs Norwesco vs Chem-Tainer comparison in the larger 2000 gallon class lays out the build differences across the major makers.
The mistake to avoid
The most common error on a vertical water tank this tall is the pad. An 8,340 pound load on a 64 x 64 inch footprint demands a flat, fully supporting, level base, not gravel or uneven soil that lets the bottom flex. Pour or verify a pad rated for the load before the tank arrives, and check the technical drawing on this page for the base dimensions. Our concrete pad sizing guide walks through the engineering framework. The second mistake is fill: this tank carries a 1.0 specific gravity rating, so it is sized for water and water-like fluids only. If your liquid is heavier than water, do not put it in this tank, call 866-418-1777 or check the Tank Sizing Guide for a tank rated to the right specific gravity.
