The Enduraplas 5000 Gallon Vertical Liquid Storage Tank is a large-format, freestanding polyethylene tank built for bulk water storage where footprint efficiency and capacity both matter. It stands 150 inches tall on a 110 x 110 inch base, holding 5,000 gallons in a single vertical column. Dimensions on this listing are verified against the launch spec, so the numbers you plan your pad and plumbing around are the numbers you receive.
Will it work for your site?
The tank measures 150" H x 110" W x 110" L, giving a 110 x 110 inch footprint. Filled with water it carries a roughly 41,700 lb operating load, so the pad underneath has to be engineered for that weight: a full-diameter, level concrete or compacted base, not gravel or partial support. Per the technical drawing on this page, the tank is outfitted with a 3 inch bolted fitting for your outlet or fill line and a 16 inch lid for access and inspection. This is a vertical bulk water storage tank sized for fire-water reservoirs, agricultural and irrigation supply, rainwater capture, and process water holding. If you are still confirming volume against draw-down and refill rates, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a pad pour.
Plumbing and venting the fittings
The 3 inch bolted fitting is a flanged connection, not a threaded bulkhead: it seals against a gasket, so confirm the gasket material matches your fluid and plan a 3" bolted-flange-to-pipe transition as a separate line item, since no adapter or gasket is listed with the tank. The 16 inch lid is your top access point for inspection and for venting. A column this tall must be vented so it does not pull a vacuum and collapse inward on a fast draw-down, so keep the lid path open to atmosphere or fit a proper vent before you run high-flow discharge.
The mistake to avoid
This tank is built and rated for water and comparable liquids. The specific-gravity rating is not listed on this pack, so before ordering for any fluid denser than water (1.0 SG) - fertilizer solutions, brines, many liquid chemicals - call 866-418-1777 to confirm the SG rating first. Anything heavier than plain water can overstress the wall if the tank is not rated for it. Match the tank to the actual fluid, and confirm your outlet plumbing lands on the 3 inch bolted flange rather than assuming a threaded connection.
