The Chem-Tainer 850 Gallon Vertical Storage Tank is a 124-inch-tall polyethylene tank on a compact 48 x 48-inch footprint, molded in Natural White so you can eyeball the water level through the wall. It is built for straightforward bulk water storage - rainwater and reuse collection, irrigation buffering, and rural fire-water reserves - where you need real volume without a sprawling ground print.
Will this vertical storage tank hold up for the job?
The vertical body carries an 850-gallon working capacity in a stable, self-supporting shape. Filled with plain water it weighs about 7,089 pounds, but the shell is rated to a 1.5 specific gravity - meaning the wall is spec'd to carry contents up to roughly 10,634 pounds. That is the strongest reason to buy this white vertical storage tank: the wall thickness sits well above what plain water demands, so you get a wide safety margin at full fill and room to store denser fluids up to 1.5 SG. It is a genuinely heavy-duty water tank, not a light rain barrel scaled up.
How it ships
This is an LTL freight item, quoted live to your ZIP. It ships from the nearest Chem-Tainer plant - Marked Tree, Arkansas or Merced, California - and which origin serves you is the single biggest driver of your freight cost. As a rule, East and Central ZIPs quote against Arkansas and West Coast and Mountain ZIPs quote against California. Get a real number in seconds with the Freight Cost Estimator, or call 866-418-1777 to talk through delivery. Because a 124-inch tank is a tall, oversized load, LTL delivery is curbside rather than placement - have equipment or hands ready to offload.
The mistake to avoid
The most common error on a tank this size is setting it on soft or partial support. A vertical storage tank fights to stay round, and an uneven base puts that seven-thousand-plus-pound load onto a fraction of the footprint and stresses the sidewall. Build a full-contact, level 48 x 48-inch pad rated for the full water weight before fill day. Our concrete pad sizing guide walks through the ACI framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm this is the right volume before you commit. If you are sizing a fire-water reserve, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and for aggregated rainwater or process water the water reuse topology guide maps how quality-banded storage trains fit together. Check the technical drawing on this page for exact dimensions and fitting locations.
