The Enduraplas 450-gallon beige vertical water storage tank stands 94 inches tall on a 40 x 40 inch footprint - the size of a standard pallet - putting 450 gallons of water storage into a single floor square instead of sprawling sideways. Filled with plain water it carries about 3,753 pounds; at its full 1.1 specific gravity rating the contents reach roughly 4,128 pounds. Built from polyethylene, it is a straightforward vertical storage tank for sites that need real volume in a tight ground footprint, and the beige color cuts sunlight penetration to slow algae growth in outdoor service - a fit for equipment yards, pump houses, and rural water storage runs.
Will it work for your site?
Quick dimensions: 94 in tall, 40.0 x 40.0 in footprint. Plan your slab and stand around the loaded weight, not the empty shell. The 4,128-pound max-rated contents weight lands on that 40 x 40 inch base, so the pad underneath has to be flat, level, and continuously supported across the whole footprint. If you are sizing a pad for an above-ground polyethylene tank, our concrete pad sizing guide walks through the ACI framework for getting it right. To confirm 450 gallons is the volume you actually need, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide.
The 1.1 specific gravity rating, and where it lands
The 1.1 specific gravity rating means this tank is engineered for liquids up to 1.1 times the density of water. Water sits at 1.0, so for water storage you have comfortable headroom. The single most common mistake on a vertical water tank this tall is reading the SG rating as a chemical clearance: it is a structural density rating, not a chemical-compatibility statement. For water service, fill it and move on; for anything denser than water, confirm the wall thickness against the contents you intend to store before you commit. This tank suits water storage, vertical storage tank duty, and beige water-tank installs where keeping a small ground footprint matters.
Commissioning and acceptance
Before you put a new install into service, fill it under controlled conditions and watch the pad and fittings. Our hydrostatic test methodology guide covers water-fill discipline, pad-settlement monitoring, and fitting leak detection with real hold-time math. If this 450 is feeding a private fire-protection setup or a water-reuse train, the fire-water reservoir design guide and the industrial water reuse topology guide show how a tank like this fits the larger system. See the technical drawing on this page for fitting locations and exact dimensional callouts.
