The Chem-Tainer 75 Gallon Rectangular Open Top Tank is a straightforward polyethylene container for water and general-purpose liquid storage where you need easy access from the top for filling, mixing, dipping, or manual cleanout. Its rectangular footprint sits tighter against walls and inside curbed containment than a round tank of the same volume, which makes it a practical choice for benches, wash stations, and batching setups that are short on floor space.
Will it work for your setup?
This is a 75-gallon rectangular open top tank molded from polyethylene. The load-bearing fact for your install is the filled weight:
Full water weight: ~626 lb (75 gallons of water)
Plan the supporting surface for that load — a flat, fully continuous, level pad with no gaps under the base. Because the top is open, this tank is meant for atmospheric (vented) storage at ambient conditions, not for pressurized or sealed service. If you are not sure whether 75 gallons is the right working volume once you allow for freeboard and drawdown, run the numbers with our Tank Sizing Calculator or walk through the Tank Sizing Guide before you commit.
Configuring the tank
As listed, this is an open top rectangular tank without factory-installed fittings. If your application needs a bottom drain, bulkhead outlet, or overflow, confirm the placement and thread size you want before ordering, and check the technical drawing on this page for the base dimensions so your plumbing and containment line up. Open top tanks like this one are commonly searched as an "open top tank," a "rectangular open top tank," or simply an "open tank," and the flat sidewalls make them easy to drop into rectangular secondary containment.
