The Chem-Tainer 550 Gallon Vertical Storage Tank is a black polyethylene tank built for bulk water and general liquid storage where a compact 45-inch-square footprint has to hold real volume. Standing 94 inches tall on a 45 by 45 inch base, it stores 550 gallons in the upright, space-saving form that farms, fire-protection reserves, and industrial water-reuse systems reach for first. Here is what you need to know to buy it right: how much it weighs full, how it ships, and the one spec that trips people up.
Does it work for your job?
Filled with water, this vertical storage tank carries about 4,587 pounds of contents, so the pad or slab under it has to be sized and level for that load. Its 1.5 specific-gravity rating means it is engineered to hold denser liquids up to roughly 6,880 pounds of rated contents weight. Match this size to the demand you are planning around by running the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. The tank's overall dimensions are shown on the technical drawing on this page; fitting configuration - outlets, bulkhead fittings, and gasket material - is not listed for this SKU, so confirm those with us at 866-418-1777 before you order.
What about freight?
At this size and weight the tank ships LTL freight, not parcel. It ships from a Chem-Tainer plant - Hanford, CA or Marked Tree, AR - with the actual origin and cost confirmed live to your ZIP code, so where you take delivery drives the number. Get a real quote in seconds with our Freight Cost Estimator, or call 866-418-1777 and we will quote it by phone. For siting the tank, the concrete pad sizing guide walks through building a base rated for the full load.
The mistake to avoid
The trap on a tank rated to 1.5 specific gravity is treating that number as permission to store anything. The rating is about density - it confirms the tank can carry a liquid up to 1.5 times the weight of water - not about chemical resistance. This is a water-service listing, set up for irrigation, rainwater and grey-water reuse, and rural fire reserves. Any non-water use requires OEM chemical-compatibility sign-off on both the resin and the gasket material for your specific liquid before you fill it - do not assume it because the SG rating is high. For water duty, it is a straightforward fit. See our writeups on fire-water reservoir design and industrial water-reuse tank topology to plan the wider system.
