The Enduraplas 10000 Gallon Plastic Vertical Liquid Storage Tank in Faint Green is a polyethylene vertical tank built for large-volume water and liquid storage, where a single high-capacity vessel beats a bank of smaller ones. It stands 178 inches tall (about 14.8 feet) on a 144 x 144 inch (12 ft x 12 ft) footprint, holds 10,000 gallons, and carries a 1.9 specific gravity rating - meaning it is built to hold contents up to 1.9 SG, not just water at 1.0. That is real headroom: a 1.9 SG rating covers heavier liquids and many solutions that a typical 1.0-1.5 water tank cannot, so this vertical storage tank works for more than plain potable or process water.
Will this tank work for your site?
Two numbers drive every decision on a tank this size: weight and footprint. Filled with water, this tank weighs about 83,400 lb, and at its full 1.9 SG rating the contents alone can reach 158,460 lb (roughly 15.85 lb per gallon). That load lands on a 144 x 144 inch base, so the pad underneath has to be engineered for it - this is not a tank you set on bare gravel. Work through the numbers with our Tank Sizing Calculator and Tank Sizing Guide, and before you pour, read our walkthrough on concrete pad sizing for above-ground polyethylene tanks, which lays out the ACI 360R-10 framework. For a full rundown of plumbing, venting, and placement on this exact size, our 10000 gallon vertical liquid storage tank buyer's guide covers it end to end.
Venting, clearance, and the mistakes to avoid
The single most common error on a tank this large is undersizing the vent. A 10,000-gallon vertical that fills or drains fast moves a lot of air, and an inadequate vent can pull a vacuum on the tank wall during outbreathing or let it balloon during inbreathing. Our worked examples on atmospheric vent capacity calculations run the API 2000 math for thermal inbreathing, liquid-movement outbreathing, and combined sizing on verticals from 1,500 up to 10,000 gallons. The second mistake is treating clearance as an afterthought: confirm overhead and door access for a roughly 14.8 ft tall, 12 x 12 ft tank, plus crane or forklift reach, before delivery day. If this tank is part of a private fire-protection plan, our guide on fire-water reservoir tank design for rural and remote sites walks through NFPA 22 sizing discipline and cold-climate freeze protection.
Fittings and freight
Outlet, bulkhead, and gasket configuration on this tank is confirmed at order - call 866-418-1777 to spec exactly what you need plumbed before it ships, so nothing has to be reworked in the field. On freight, a tank this size ships LTL on its own from the nearest Enduraplas plant - either Converse, TX or Neche, ND. You do not pick the origin; the routing is determined at quote time by your ZIP to keep the freight cost down, and the 12-foot footprint means specialized handling at delivery. Get an exact, ZIP-specific number with our Freight Cost Estimator before you order, or call 866-418-1777 to talk through delivery and offload on a tank this large. Freight is quoted live to your ZIP and is separate from the tank's list price.
