The Chem-Tainer 800 Gallon Open Top Batch Storage Tank (SKU TC7246AA) is a cylindrical, open-top polyethylene vessel built for batch mixing, water staging, and bulk liquid holding where you need full top access to the contents. It stands 46 inches tall on a 72 x 72 inch footprint, holds 800 gallons in natural white polyethylene, and carries a 1.9 specific gravity rating - meaning this is a heavy-duty shell engineered to hold contents far denser than water, not a base-grade water tank.
Will it work for your batch?
This is a true open top tank, sized for processes where you fill, mix, draw down, and refill - not for sealed long-term storage. The 72-inch open mouth and 46-inch height set the practical ergonomics: an adult can reach in for manual additions and cleaning, and the full 72-inch diameter gives you the clearance to drop in an agitator or mixer. That open configuration is the same white open top storage tank format batch and dosing lines rely on for visual level checks and easy additions. To match this 800-gallon size to your throughput, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit.
Load, footprint, and foundation
For your pad contractor, the numbers that matter at a glance:
- Full of water: roughly 6,672 lb
- At full 1.9 SG rating: up to about 12,677 lb of contents
- Footprint: 72 x 72 in (36 ft²), about 352 lb/ft² at the full rated load
Because this is a flat-bottom open top tank carrying real weight, it belongs on a smooth, fully supporting, level pad. For a vessel in this weight class, an above-ground concrete pad is the right foundation - our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the slab handles the loaded weight without point-loading the tank floor.
Fittings and dense-batch service
Our data does not list factory fittings or gaskets for this open top tank, so do not assume any are included. Any bulkhead fitting, gasket, or outlet must be confirmed against the technical drawing on this page and ordered to match your plumbing - refer to that drawing for the exact bottom profile and any factory outlet detail before you set fittings. If you are staging solids-laden or higher-density batches and need full, clean drainage with minimal residual heel, a cone-bottom configuration drains better than this flat-bottom open top; our comparison of Chem-Tainer cone-bottom tanks at 30° vs 45° covers the trade-offs.
The mistake to avoid
The common error on a heavy-duty open top like this is treating the 1.9 SG rating as a license to skip pad engineering. The rating tells you the shell can hold dense contents; it does not mean the ground underneath can. Size the foundation to the loaded weight, not the empty tank, and keep the tank on a continuous flat surface. If you are using this for water staging or fire-water reserve, our writeup on fire-water reservoir tank design and our industrial water reuse tank topology guide cover the design discipline that keeps a storage tank reliable over its service life.
