The Chem-Tainer 70 Gallon PE Rectangular Open Top Tank is a polyethylene rectangular open-top vessel built for above-ground water storage, batching, and washdown work where you need easy top access to add, measure, or dip into the contents. At 70 gallons in a rectangular footprint, it sits flatter against a wall and into corners where a round tank wastes floor space, and the open top makes it straightforward to fill, clean out, and inspect. This is a water-service tank - think rectangular open top tank for general open-top water storage, rainwater catch, and similar above-ground holding work.
Will it work for your application?
The tank holds 70 gallons and is molded from polyethylene. Filled to capacity with plain water, plan for roughly 584 pounds of total liquid weight based on water at SG 1.0 - that number drives your pad, platform, or shelf decision more than anything else. Above-ground polyethylene tanks of this size want a flat, fully supported, level base; if you are setting it outdoors or on a built-up platform, our concrete pad sizing guide walks through the support framework using the ACI 360R-10 approach. Not sure 70 gallons is the right capacity for your draw and refill cycle? Run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide before you buy. Because the exact length, width, and height drive whether it slots into your space, confirm the footprint dimensions at quote - call 866-418-1777 and we will read them to you before you commit.
How it ships and what it costs to get there
This open-top tank ships LTL freight from West Babylon, New York, the nearest stocking plant, and freight is quoted live to your ZIP code. Because rectangular open-top tanks are bulky, freight depends heavily on distance and your delivery setup - liftgate, residential, or dock.

The mistake to avoid
The single most common error with an open-top rectangular tank is expecting it to arrive plumbed. This tank ships as an open-top vessel with no pre-installed bulkhead fittings, outlets, or bottom drain - the open top is access, not a structural lid, and any draw-off or overflow plumbing is something you add after delivery. Do not stack weight on the rim or let anything bridge across the top edge; keep the load inside the tank and support the full base. If your install is part of a larger reuse or capture system, our guide on industrial water reuse tank topology covers how open-top storage fits into grey-water, rainwater, and condensate trains, and our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate water storage.
