The Enduraplas 1200 Gallon Vertical Water Storage Tank is a black polyethylene bulk tank built for steady above-ground water storage on farms, job sites, rural fire-water reserves, and industrial reuse trains. It holds 1200 gallons in a squat vertical profile that stays compact where floor space is tight, and its opaque black wall blocks light to slow algae growth in stored water. Dimensions are verified: 76 inches in diameter and 68 inches tall, sitting on a 76 x 76 inch footprint. That low center of gravity over a wide 76 inch base makes it a stable stand without guy-wires in most siting conditions.
Will it work for your site?
Plan the pad and the plumbing around a full tank, not an empty one. At 1200 gallons, water alone weighs roughly 10,008 pounds when the tank is topped off, so it must sit on a level, fully supporting foundation rated for that load. Undersized or uneven pads are the most common cause of stress cracking and fitting leaks over time. Note that 10,008 pounds is water-only weight for offload planning; if you need the tank's dry shipping weight for your forklift or crane call, ring 866-418-1777 and we will confirm it before delivery. If you are sizing storage for a specific draw rate or reserve target, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. For a poured foundation, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework.
The mistake to avoid: confirm the specific gravity rating
This is a water tank. Before you store anything denser than water, such as liquid fertilizer or brine, confirm the tank's specific gravity rating against Enduraplas paper. The wall thickness that carries 1200 gallons of water at SG 1.0 may not be rated for a heavier fluid, and pushing past the rating is how vertical poly tanks fail early. Do not assume the rating from capacity alone. Fitting configuration also varies on these tanks, so call 866-418-1777 to confirm outlet size and gasket material before you order rather than assuming a layout. See the technical drawing on this page to check overall dimensions against your plumbing plan.
Common uses and setup discipline
This 1200 gallon vertical poly water tank suits bulk water holding, irrigation supply, rainwater and grey-water capture, and rural fire-protection reservoirs. If you are building a private fire-water reserve, read our NFPA 22 sizing and freeze-protection breakdown, which covers the freeze-protection engineering the tank itself does not include; for reuse and aggregation systems, the industrial water reuse tank topology guide covers quality-banded storage trains. After install, prove the tank and its fittings before you rely on them: our hydrostatic test methodology covers water-fill discipline, pad settlement monitoring, and hold-time math.
