The Chem-Tainer 2100 Gallon Green Vertical Water Storage Tank is a single large-volume vertical tank for above-ground bulk water service, with a 2,100 gallon nominal capacity. It stands 87 inches tall on an 87-inch round footprint and is molded in polyethylene with a green exterior that cuts light penetration to slow algae growth in stored water. That green-color advantage matters most on long-dwell water - a private fire reserve that sits full for months, or a captured-rainwater train where the water isn't constantly turning over. Whether you are building a fire reservoir, a rainwater catch system, or an agricultural or industrial water supply, this tank gives you 2,100 gallons in a compact 87 x 87 inch base.
Will it hold your water
This is a 1.0 specific-gravity tank, rated for water and other contents up to the weight of water (8.34 pounds per gallon) - not for heavier liquids. Filled to its 2,100 gallon nominal capacity, the tank carries roughly 17,514 pounds, which is also its maximum rated contents weight, so plan your pad and foundation around that load. For a vertical water storage tank of this volume, the weight goes straight down onto the footprint, so a level base that supports the entire 87-inch circle is essential. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this size matches your draw and refill cycle before you order, and confirm fitting and outlet locations on the technical drawing on this page before you plumb it.
What to get right before you set it
The single most common mistake with a tank this large is the foundation. At 17,514 pounds full, the tank needs a continuous, level support surface under the entire base - not a partial ring, not bare uneven soil. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that pad right. The second mistake is the SG mismatch: because this is a 1.0 SG tank, keep its use to water and water-weight contents. If you need to store something heavier than water, do not fill this tank with it - call 866-418-1777 and we will quote a higher-SG-rated tank built for that duty. If you are weighing brands at this volume, the Snyder vs Norwesco vs Chem-Tainer 2000 gallon vertical comparison lays out the trade-offs.
Application fit
As a vertical water storage tank in the 2,000-gallon class, this unit suits private fire-water reservoirs, captured rainwater and reuse trains, and general bulk water storage. For fire-protection planning, see our write-up on fire-water reservoir tank design for rural and remote sites, which covers NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or HVAC condensate, our industrial water reuse tank topology guide covers quality-banded storage trains.
This tank ships LTL freight from a single plant in Hanford, CA, so freight is the question to settle before you commit - especially on a long haul east. At 17,514 pounds full and shipping empty by the truckload, get your ZIP quote first with the Freight Cost Estimator, then call 866-418-1777 to talk through sizing, foundation, and delivery with our team.
