420 Gallon Plastic Vertical Liquid Storage Tank in Dark Green

The Bushman 420 Gallon Vertical Liquid Storage Tank in Dark Green is a free-standing polyethylene tank built for above-ground bulk water storage. It holds 420 gallons in a 47 x 47-inch footprint and stands 64 inches tall — so the whole unit tucks into a corner, a pump house, or a fenced equipment pad without demanding wide clearance. Whether you are staging irrigation water, rainwater, or a rural fire-water reserve, this is the kind of Bushman vertical storage tank operators reach for when they want simple, gravity-friendly bulk water storage.

Will it work for your site

Start with the numbers that govern the install: 420 gallons, 64 inches tall, on a 47 x 47-inch base. Filled with water, the tank weighs about 3,503 pounds, and that load rides entirely on the 47 x 47-inch footprint — so the pad underneath has to carry roughly 3,503 lb across that area without settling or tipping. Above-ground polyethylene tanks want a flat, fully supporting base, never point loads or partial bearing. If you are pouring a new slab, our concrete pad sizing guide walks through the ACI 360R-10 framework for slabs under poly tanks. Not sure 420 gallons matches your draw-down and refill cycle? Run it through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit. See the technical drawing on this page for the tank profile and dimension callouts.

Fit for the job

For rural and remote water reserves, a vertical poly tank like this one is a common building block in a private fire-protection stack — our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. If this tank is part of a water-reuse train handling grey water, rainwater, or HVAC condensate, our water-reuse topology guide shows where quality-banded storage fits in the sequence.

One mistake to avoid

On any above-ground poly tank, inspect the vapor-saturated headspace at the top of the wall — not just the liquid side — since that is where premature wall failures tend to originate. The HDPE wall-thickness article explains the ASTM D1998 logic behind it, so your inspection routine catches trouble where it actually starts.
