The Chem-Tainer 2450 Gallon PE Cylindrical Open Top Tank is a heavy-duty open-top water reservoir molded in natural white polyethylene, rated to a 2.0 specific gravity and standing 84 inches tall on a 95-inch diameter footprint. The open top makes it straightforward to gravity-fill, inspect, and clean, which is why operators search for it as a cylindrical open top tank for bulk water staging, process holding, and reservoir service. This page covers what it holds, how it ships, and the one sizing decision that trips people up before they pour a pad.
Will it work for your application?
This is a 2,450-gallon cylindrical open top tank in natural white polyethylene, 95 inches in diameter and 84 inches in height. The 2.0 specific gravity rating means the wall is built for liquids up to twice the weight of water, so for clean-water duty the tank is heavily over-specified, with full margin for a long service life. The open-top design suits gravity fill, top-mounted level instruments, and easy interior access, and it reads as a white open top tank for water staging, reuse holding, and reservoir service. One thing to plan for up front: this open-top tank ships without pre-installed outlets or fittings, so any bulkhead, gasket, and drain penetration is a separate field installation, not an included port. The open rim is sized for full interior access; if your site needs debris, insect, or contamination exclusion, plan a cover separately, since none is included.
Weight, pad, and sizing
Plan the support before delivery. Filled with water, this tank carries roughly 20,433 pounds, and at its full 2.0 specific gravity rating the contents alone can reach 40,866 pounds. A load that size demands a level, continuously supported, engineered base across the entire footprint, not a partial ring or scattered piers. Lay out the pad for the full 95 in x 95 in footprint with at least 84 in of vertical clearance to the rim, plus overhead room above for the fill point and any top-mounted level instrument. Walk the numbers with our Tank Sizing Calculator and Tank Sizing Guide first, then size the slab using our guide on concrete pad sizing for above-ground polyethylene tanks. If this reservoir feeds a rural or remote fire-protection stack, our write-up on fire-water reservoir tank design for rural and remote sites walks through NFPA 22 sizing and cold-climate freeze protection.

The mistake to avoid
The trap on a tank this size is treating it like a smaller reservoir on the pad. An empty open-top tank is light and easy to set, but once it is full it is supporting tens of thousands of pounds, and an uneven or undersized base will flex the floor and shorten the tank's life. Confirm a full-footprint, level foundation before you fill, and never assume the open top adds structural rigidity. Verify the rim height and diameter against your fill point and clearance before you commit the slab.
This tank ships LTL freight from the Chem-Tainer plant in Hummelstown, Pennsylvania, with freight quoted live to your ZIP code. Because it ships from that single plant, freight scales with distance, and Northeast sites quote lowest.
