The Enduraplas 4000 Gallon Plastic Vertical Liquid Storage Tank is a large-capacity vertical tank built for bulk water and liquid storage where you need serious volume above ground. It stands 124 inches tall on a 110 x 110 inch base - that base is the tank's own diameter, so plan on roughly 9 feet 2 inches across when you check gate widths, door clearances, and crane or forklift swing for offload. Dimensions on this unit are verified, so you can size a pad and plan clearances before the tank ever ships.
Will it work for my site?
This is a vertical storage tank rated at 4,000 gallons. Filled with water it carries roughly 33,360 pounds, so the pad and soil beneath it must be engineered for that load - a level, properly sized concrete pad is not optional at this size. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks so you get the base right the first time. Still confirming volume for your demand? Run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide. For rural and remote fire-protection reservoirs, the NFPA 22 sizing discipline write-up covers where a plastic tank of this class fits in the private fire-protection stack. This tank is verified for water; for any liquid with a specific gravity above 1.0, confirm the tank's SG rating with us at 866-418-1777 before you order, since a heavier liquid puts more load on the wall than water does.
Fittings and access
Per the technical drawing on this page, this tank comes with a 3 inch bolted fitting for your outlet or bulkhead connection and a 16 inch lid for fill and inspection access. Usable gravity head depends on where your outlet sits relative to that 3 inch fitting, so confirm the fitting elevation on the drawing before you plan any gravity-fed or pumped distribution run. The drawing lists the 16 inch lid and the single 3 inch fitting only - a 4,000 gallon tank still needs venting sized to your fill and draw rate, so confirm vent provisions before commissioning.

The mistake to avoid
At 33,360 pounds full, the most common and most expensive error is under-building the base. Do not set a 4,000 gallon tank on bare, un-compacted, or uneven ground - a plastic tank needs uniform, full-contact support across the entire footprint, or the wall will carry stress it was never designed to hold. Size and pour the pad to match the 110 x 110 inch footprint before delivery day. If you are reusing grey water, rainwater, or HVAC condensate, the water reuse tank topology guide covers how a tank like this fits into a quality-banded storage train.
