The Chem-Tainer 90 Gallon PP Cylindrical Open Top Tank is a natural white polypropylene vessel built for straightforward bulk water holding, batching, and transfer where you need easy top access. It stands 48 inches tall on a compact 24 x 24 inch footprint, so it fits a tight corner, a mix station, or a pump skid without eating floor space. The open top makes it simple to fill, monitor, stir, or lower a pump into, and the cylindrical body keeps the water column stable and easy to clean out. Because the shell is molded from polypropylene rather than the standard-grade white poly used on most water tanks, it tolerates warmer process and batch water better, which is useful when the liquid going in is not always at ambient temperature.
Will it work for your job?
Rated at 90 gallons, this open top tank holds roughly 751 pounds of water when full. That full-water weight is the number that matters for planning: your stand, pad, or platform has to carry it, and all of that load rides on the 24 x 24 inch footprint. Set it on a flat, fully supporting surface, not on ribs or spanning a gap, and pour a base sized for the load. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground tanks so the foundation matches the weight. If you are unsure whether 90 gallons fits your draw-down or refill cycle, run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide before you commit. As a cylindrical open top tank, it also fits neatly into staged holding and reuse trains for grey-water, rainwater, and condensate collection, covered in our industrial water reuse tank topology guide.
One thing not to get wrong
This is an open top vessel, so it is a holding and process tank, not a pressurized or fully sealed one. Do not treat it as a closed system: leave headroom for agitation and splash, and plan a lid or cover separately if you need to keep debris, insects, or evaporation out. It is not intended for pressurized plumbing or gravity-feed setups that assume a closed head. Just as important, watch the geometry: at 48 inches tall on a 24 x 24 inch base, this tank is roughly twice as tall as it is wide, so a full 751-pound load sits high and narrow. Strap or anchor it when full, especially on an elevated stand, and confirm the footprint and height against your space before you build the support.
