The Enduraplas 150 Gallon Green Vertical Storage Tank (SKU THV00150G) is a 150-gallon polyethylene vertical tank standing 61 inches tall on a compact 30-inch by 30-inch footprint. What separates it from a typical water-only tank is the 1.9 specific gravity rating: most plain water tanks are built to a 1.0 to 1.5 rating, so this Enduraplas vertical storage tank carries real structural headroom in the wall, with margin to spare for plain water, sediment-laden, or recovered water. Molded in green polyethylene by Enduraplas, it drops onto a small pad and stores a meaningful volume in a tight 150-gallon footprint.
Will it work for your site?
Empty, this tank occupies a 30-inch by 30-inch square, so it fits through standard gate widths and onto a modest concrete pad or compacted base. Filled with water it weighs about 1,251 pounds, and the 1.9 specific gravity rating allows total contents up to roughly 2,377 pounds. That ~1,126-pound gap between full-water weight and max rated contents is the structural headroom the 1.9 rating buys you, which tells an engineer exactly how much margin sits in the wall. Plan your pad and any platform around the loaded figure, not the empty shell. If you are weighing this 150-gallon size against a larger or smaller vertical, our Tank Sizing Calculator and the Tank Sizing Guide walk you through capacity, footprint, and refill cadence so you neither under- nor over-buy.
Mounting and the loaded-weight rule
Above-ground polyethylene tanks need full, continuous support under the entire base. At 61 inches tall on a 30-inch base, this is a roughly 2-to-1 tall-and-narrow profile, so an empty unit is light and easy to tip until it is filled and a partial or uneven pad concentrates that 2,377-pound rated load on the low spots and stresses the wall over time. Set a level base at least as wide as the 30-inch by 30-inch footprint. For pad thickness and reinforcement, our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI framework.
The mistake to avoid
Read the 1.9 specific gravity rating correctly: it is the heaviest liquid density the tank is built to hold, not a chemical-service approval. This is a water storage tank, so for any liquid heavier or more aggressive than water, verify compatibility against the manufacturer's chemical-resistance chart before you fill. One more thing to confirm up front: fitting and lid configuration is not listed in our spec data, so call 866-418-1777 to confirm outlet size and lid before you order. If you are sizing this tank for a rural fire-water reserve, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing and freeze protection; for rainwater collection see our rainwater harvesting first-flush diverter sizing guide; and for greywater or condensate aggregation see our industrial water reuse tank topology guide. The dimensions on the technical drawing on this page confirm the height, footprint, and fitting layout.
