The Chem-Tainer 75 Gallon PE Rectangular Open Top Tank is a straight-sided, open-top polyethylene vessel built for water-service duty: bench-level batching, parts washing, rinsing, soaking, and short-term water holding where you need easy top access to a rectangular footprint. At 75 gallons, the tank holds roughly 626 pounds of water when full, so the surface it sits on has to carry that load without flex. This is the right size when you want an open tank you can reach into, dip from, or plumb a portable pump over without fighting a domed lid.
Will this rectangular open top tank work for your job?
This is a 75-gallon rectangular open top tank molded in polyethylene by Chem-Tainer, positioned for water and water-reuse holding rather than chemical storage. The open top means no lid to remove and full visual access to the contents, which is why open-top tanks like this one get used for mixing, rinsing, soaking, and short-term holding. Run the numbers before you build the stand: a full tank is about 626 pounds, so size your platform and anchoring to that figure, not to the dry weight. If you are not sure whether 75 gallons is the right volume for your batch or holding cycle, work through the Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Mounting and placement
Because this is an open-top rectangular tank, it sits flush against walls and lines up edge-to-edge in a row better than a round tank, which is part of why rectangular open tanks are picked for tight bays and benches. Set it on a flat, continuous, fully supporting surface so the flat bottom is uniformly bearing the 626-pound full load. If you are pouring a slab for this or any above-ground polyethylene tank, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting the pad right.
The mistake to avoid
The most common error with an open-top tank this size is under-building the support and assuming the dry tank weight is what matters. Water is heavy: 75 gallons is about 626 pounds, and the open top gives you no structural lid to tie the walls together, so the platform and any side bracing have to handle the full filled weight. Design the stand around 626 pounds, keep the bottom fully supported, and don't perch it on point loads. If this open tank is buffering or holding for a larger water-storage system, the industrial water reuse tank topology guide covers how holding and aggregation tanks fit into a grey-water, rainwater, and condensate train. If you are sizing an open-top reservoir for rural fire protection, our fire-water reservoir tank design guide covers the NFPA 22 sizing discipline and cold-climate freeze protection.
