The Enduraplas 150 Gallon Dark Green Vertical Water Storage Tank (SKU TLV00150DG) is a 150-gallon polyethylene vertical storage tank built for outdoor water storage where a compact 30-inch footprint matters. It stands 61 inches tall on a 30 x 30 inch base, so it fits tight equipment pads, well houses, and corners where a wider tank won't go. The dark green color slows algae growth by cutting light penetration into the stored water, and the tank carries a 1.1 specific gravity rating, meaning it's engineered to hold liquids up to 1.1 times the weight of water.
Will it work for your site?
The single most site-limiting fact is load per footprint: a full tank weighs 1,251 pounds and is rated to carry contents up to 1,376 pounds, all concentrated on that 30 x 30 inch base. That's real load on a small footprint, so an above-ground polyethylene tank needs a flat, fully supporting pad - not a wood deck or an uneven slab. Our concrete pad sizing guide walks through the ACI framework for getting that pad right the first time. If you're still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to demand. This 150-gallon vertical storage tank is a common pick for rural fire-water reserve, backup household water storage, and small water-hauling setups.
Fittings and setup
Confirm the fitting layout with us before you plumb the tank - see the technical drawing on this page, or call 866-418-1777 and we'll walk it through with you - and match your bulkhead and valve sizes to your line before install. For a proper acceptance test after setup, our hydrostatic test methodology guide covers water-fill discipline, pad settlement monitoring, and fitting leak checks so you catch problems before the tank goes into service.
The mistake to avoid
The 1.1 specific gravity rating is for water and water-like liquids. Put another way, the 1,376 lb content rating over 150 gallons works out to about 9.17 lb per gallon - that's your ceiling. Check your liquid's weight per gallon against it. Denser liquids like fertilizer solutions and brines exceed what the wall is rated to carry and can shorten tank life. If you need fertilizer, brine, or chemical service above 1.1 SG, call 866-418-1777 and we'll match you to a higher-rated tank. If you're planning grey-water or rainwater reuse instead, our water reuse topology guide covers quality-banded storage trains.
