The Chem-Tainer 153 Gallon PE Rectangular Open Top Tank is a polyethylene rectangular open top tank built for bulk water handling, mixing, and full-top-access processing where a closed vertical won't fit the bay. The square-shouldered footprint slots into floor-space-tight installs better than a round tank of the same 153-gallon volume, which is why buyers searching for a rectangular open top tank — or just an open tank with a clear top for filling, manual additions, and maintenance — land here.
Will this tank work for your application?
This is a 153-gallon polyethylene open-top tank in a rectangular profile. Filled with water it carries roughly 1,276 lb at capacity, so the pad, stand, or platform beneath it has to be rated for that fully loaded weight plus any working surge. Open-top tanks are sized to the brim, not to a fill line, so run your real working volume through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to this size — an open-top rectangular design gives up some usable headroom to splash and freeboard compared to a closed tank. Confirm the floor or sub-base is level and continuously supported across the full footprint; a rectangular flat-bottom tank loads its base evenly only when it sits on a true plane.
Freight and where it ships from
This Chem-Tainer tank ships by LTL freight from the West Babylon, New York plant, quoted live to your ZIP. Open-top tanks ship upright and uncrated, so a forklift or dock makes unloading far easier than a liftgate-only delivery — flag any access limits when you book so the carrier sends the right equipment. Get your real number with the Freight Cost Estimator, or call 866-418-1777 and we'll line up the freight for you.
The mistake to avoid
The common error on an open-top water tank is treating it like a sealed system. There is no lid or tight cover specified here, so this tank is built for atmospheric, vented service — not pressure, and not for anything that can't tolerate evaporation or airborne contamination through the open top. A flat-bottom open vessel also has no built-in drainage slope to shed water before it ices, so for outdoor or freeze-prone sites plan freeze protection up front; our fire-water reservoir design guide covers freeze-protection engineering for cold-climate service. If your process actually needs clean drain-down or solids handling rather than full top access, a sloped tank is the better tool — the Chem-Tainer cone-bottom 30° vs 45° drainage guide compares residual heel and solids-handling performance so you can decide before you buy. And if you're aggregating rainwater, grey-water, or process water across stages, the industrial water reuse tank topology guide shows how open-top storage fits a quality-banded train. To build a base that supports the full water weight evenly, see our guide on concrete pad sizing for above-ground polyethylene tanks.
