The Enduraplas 550 Gallon Vertical Water Storage Tank (SKU TC4594IW-BLACK) is a black polyethylene bulk tank built for above-ground water storage. It holds 550 gallons in a compact vertical footprint of 45 by 45 inches and stands 94 inches tall, so it stores real volume without sprawling across a site. The dimensions on this listing are verified, and you can confirm the tank profile against the technical drawing on this page before you commit to a pad layout.

Will it work for your site?
This is a vertical, free-standing storage tank sized for water: rural fire reserve, water draw-down, rainwater and reuse collection, or general bulk holding. Filled to capacity, 550 gallons of water weighs about 4,587 pounds, and that entire load sits on the 45-by-45-inch footprint. Size the pad and any handling equipment for the full weight, not the empty tank. Our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to daily demand, and if this tank feeds a private fire-protection reserve, the NFPA 22 fire-water reservoir design guide walks through the sizing discipline. For reuse and rainwater trains, see the water reuse tank topology guide. For inlet, outlet, and vent configuration, call 866-418-1777 and we will spec fittings with you rather than leaving you to guess.
The mistake to avoid: the pad
The most common install error on a tall vertical tank like this one is an undersized or unlevel foundation. At 94 inches of height carrying nearly two and a half tons of water, an above-ground poly tank needs a full-contact, level base under the entire 45-inch footprint. A soft or partial pad lets the shell flex and settle unevenly. Our concrete pad sizing guide covers the ACI framework for getting the foundation right, and after install, the hydrostatic test methodology guide shows how to fill, monitor settlement, and check fittings for acceptance.
