The Chem-Tainer 1150 gallon vertical liquid storage tank is a tall column of white HDPE built for serious water volume in a compact footprint, and it is the heavy-rated build in the line. Rated to a 1.9 specific gravity with an 18,223 pound contents rating, it carries dense water-treatment liquids like brine and dosing solutions without giving up capacity. At 156 inches tall on a 48 by 48 inch base, it holds 1,150 gallons in the floor space of a four-foot square, which is why operators reaching for a vertical tank, a vertical storage tank, or an HDPE storage tank in this capacity keep landing on this Chem-Tainer model. Below are the two answers that decide the purchase: whether the tank fits your site and your liquid, and how it gets to you.
Will it work for your liquid and your site?
This is a polyethylene vertical tank rated to a 1.9 specific gravity, a heavy-duty rating well above what water service demands. Filled with water, the contents weigh about 9,591 pounds, and the tank wall is rated to carry contents up to 18,223 pounds, so you have real headroom for denser liquids, not just water. Plan your pad for the loaded weight, not the empty shell: 9,591 pounds of water on a 48 by 48 inch base is roughly 600 pounds per square foot of bearing load, and a properly sized, dead-level pad matters far more on a tall column than on a short squat tank. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 1,150 gallons is the right volume before you commit to the height.
The mistake to avoid on a tank this tall
The most common error on a 156-inch vertical tank is treating it like a short tank when it comes to siting, anchoring, and fittings. At thirteen feet of height on a four-foot base, this is a top-heavy column when empty and a very heavy one when full. Confirm overhead clearance for both the tank and the fill connection, verify the pad is level, and check whether wind or seismic anchoring applies at your location before you stand it up. On fittings, do not assume an outlet size: see the technical drawing on this page for fitting locations and dimensions, and confirm the outlet size, bulkhead fitting, and gasket compatibility against that drawing before you order. For fire-water or reserve-supply duty the height-to-volume ratio is exactly what you want, and our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection. Our HDPE wall-thickness guide explains the ASTM D1998 logic behind how these tanks are sized, and if you are weighing brand-level build quality, the Snyder vs Norwesco vs Chem-Tainer comparison (covered at the 2,000 gallon size) is a useful read on how these makers differ.
Freight and ordering
This tank ships LTL freight, quoted live to your ZIP code. For this SKU it ships from Hanford, CA, with Marked Tree, AR as the alternate Chem-Tainer plant, so West Coast buyers see the shortest hauls. Because a 156-inch tank is oversized cargo, get your number before you order: run your ZIP through the Freight Cost Estimator for a live LTL quote, or call us at 866-418-1777 and we will help you confirm fit, pad requirements, and delivery for the 1150 gallon vertical. The listed price is the tank only; freight is quoted separately to your destination.
