The Chem-Tainer 5000 gallon vertical liquid storage tank is a single-large-volume polyethylene reservoir built for bulk water and liquid storage where you need real capacity in one footprint. It stands 152 inches tall on a 102 x 102 inch base, holds 5,000 gallons, and carries a 1.5 specific gravity rating, which means it is engineered to handle liquids up to 1.5 times the weight of water, not just water itself. If you have been searching for a 5000 gallon vertical storage tank, this is the white, ground-level workhorse that anchors fire-water reservoirs, agricultural supply, rainwater capture, and process-water buffering.
The numbers that decide whether it fits:
- Overall height: 152 in
- Footprint: 102 x 102 in
- Full-water weight (tank + contents): about 41,700 lb
- Max rated contents weight at 1.5 specific gravity: about 62,550 lb
Will this tank work for your application?
Start with the weight math, because at this size it governs everything. Filled with water, the tank and its contents reach roughly 41,700 pounds; at the full 1.5 specific gravity rating, the rated contents weight climbs to about 62,550 pounds. That load sits on a 102 x 102 inch footprint, so your pad has to carry it. Plan a level, continuously supported reinforced concrete foundation rated for the full filled weight; a vertical tank this tall is unforgiving of an uneven or undersized base. The 152-inch overall height also means you should confirm your overhead clearance for delivery, placement, and fill access before the truck arrives. Run your draw-down and refill cycle through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 5,000 gallons is the right volume.
The 1.5 specific gravity rating: read this before you buy
The most common and most expensive mistake on a tank this size is treating the specific gravity rating as a detail. White polyethylene at a 1.5 specific gravity rating is sized for water and for liquids heavier than water up to that 1.5 limit. If your liquid is lighter than or equal to water, you have margin to spare. If you are storing something denser, verify your liquid's specific gravity against the 1.5 rating first, because exceeding the rating shortens tank life. Storing a liquid above 1.5 specific gravity? This tank is not rated for it; call us at 866-418-1777 before ordering. The second mistake is foundation: people pour a pad for "5,000 gallons of water" and forget that a heavier liquid pushes the real load toward that 62,550-pound figure. Size the pad to the contents you actually intend to store.
Fittings and the technical drawing
Fitting and outlet sizes and locations are not listed in this summary, so confirm them on the technical drawing on this page and check them against your plumbing layout before you order. On a 5,000 gallon tank, a wrong outlet position or a mismatched connection is an expensive thing to discover after delivery. Review the drawing against both your plumbing and your pad layout so the tank lands ready to connect.
Freight and ordering
This tank ships LTL freight, quoted live to your ZIP code. It moves from the nearest Chem-Tainer plant, either Chowchilla, CA or Hummelstown, PA, so where you are determines your origin and your rate: West-of-the-Rockies buyers typically ship from Chowchilla and Eastern buyers from Hummelstown, which keeps LTL miles and cost down on an oversized item. Get your number before you commit: run your ZIP through the Freight Cost Estimator for a live quote, or call us at 866-418-1777 and we will handle it with you. If you are weighing this against other brands or sizing a fire-water reservoir, our brand comparison guide and fire-water reservoir design guide walk through the engineering, and the two full buyer's guides cover the decision in detail: 5000 gallon vertical storage tank guide (119 x 86) and 5000 gallon vertical storage tank guide (141 x 86).
