The Chem-Tainer 3000 Gallon Plastic Vertical Liquid Storage Tank is a white polyethylene vertical tank built for high-volume liquid storage where a single large reservoir beats a bank of smaller tanks. It stands 107 inches tall on a 95 x 95 inch footprint and holds 3,000 gallons, which makes it a common choice for bulk water, rainwater capture, and rural fire-water reserves. If you searched for a vertical storage tank, a 3000 gallon vertical tank, or specifically a Chem-Tainer 3000, this is the unit you landed on, and the numbers below tell you exactly what it will and won't do on your site.
Will it work for your site?
Full of water this tank carries roughly 25,020 pounds, and at its 1.5 specific-gravity rating it is engineered to hold contents weighing up to 37,530 pounds. That spread matters: water has a specific gravity of 1.0, so a tank rated to 1.5 has real headroom for water service and can also handle denser liquids up to that 1.5 ceiling. Confirm your liquid's specific gravity before you fill - anything above 1.5 exceeds what this wall thickness is rated to carry. Need to store a liquid denser than 1.5 SG? Call 866-418-1777 - a heavier-walled, higher specific-gravity version of this footprint is available. The 95 x 95 inch footprint is the number to take to your pad: pour or level a base at least that wide, fully supporting the entire bottom, because a 3,000-gallon column of liquid concentrates enormous load. Use our Tank Sizing Calculator and Tank Sizing Guide to confirm 3,000 gallons matches your draw-down and refill cycle before you buy.
Fittings and configuration
See the technical drawing on this page for dimensional detail on this model. Outlet, fill, and vent configuration is confirmed at order, since thread sizes and gasket spec vary by build - call 866-418-1777 to lock in the fitting layout for your install. Storing a chemical rather than water? Confirm both specific gravity and polyethylene compatibility, including gasket and seal material, with our team before ordering. Note that the linked 3000-gallon buyer's guides below cover a sibling vertical tank with a slightly different 102 x 93 profile; use them for the general trade-offs, but rely on the dimensions and drawing on this page for this specific unit.
The mistake to avoid
The most expensive error on a tank this size is the foundation, not the tank. At nearly 25,000 pounds full of water and over 37,000 pounds at maximum rated contents, this unit demands a flat, continuous, load-bearing base across the full 95 x 95 inch footprint - never partial support, never a ring or a few blocks. The second mistake is assuming any heavy liquid is fine: the 1.5 rating is a hard limit, so verify specific gravity first. If you are sizing this as a fire-water reservoir for a rural or remote site, our fire-water reservoir design guide walks through NFPA 22 sizing and cold-climate freeze protection.

Freight and ordering
This tank ships LTL freight, quoted live to your ZIP code, from the nearest of our Chem-Tainer plants in Chowchilla, CA, Griffin, GA, or Lincoln, NE - so a buyer in the West, Southeast, or Midwest each ships from a different yard, which keeps the freight leg short. At 25,020 pounds full of water and up to 37,530 pounds at maximum rated contents, this is a single-tank LTL load, so run your ZIP through the Freight Cost Estimator before comparing total freight cost against a multi-tank alternative - one large tank ships as one freight leg from the closest yard. Call our team at 866-418-1777 to confirm fittings, footprint, and the nearest shipping point. Listed price is for the tank; LTL freight is quoted separately to your ZIP.
