The Norwesco 4995 Gallon Light Blue Heavy Duty Vertical Storage Tank is built for high-volume bulk water storage where one large reservoir beats a cluster of smaller tanks. Molded from polyethylene with a 1.9 specific-gravity rating, it holds 4,995 gallons on a 142-inch by 142-inch footprint and stands 89 inches tall, so plan for roughly 142 in diameter x 89 in tall when you check door, canopy, and pad clearance. The light-blue wall lets you read the liquid level at a glance. This is the size operators reach for on fire-water reservoirs, rural water systems, irrigation buffers, and industrial water-reuse trains.
Will this Norwesco vertical storage tank work for your site?
Capacity is 4,995 gallons on a 142.0 x 142.0 inch footprint, so size the pad to that. Filled with water, the water alone weighs 41,658 lb, and the foundation and surrounding grade have to carry that load without settling. The 1.9 specific-gravity rating means the wall is engineered for liquids heavier than water, up to a maximum rated contents weight of 79,151 lb, which corresponds directly to the rating (41,658 lb of water x 1.9 is about 79,150 lb). That gives you headroom if you store a denser solution, but the rule is simple: if your stored liquid's specific gravity exceeds 1.9, this tank is not rated for it, so confirm your fluid's SG before ordering. For a methodical walk-through of matching tank size to demand, use the Tank Sizing Calculator and the Tank Sizing Guide.
Pad and foundation come first
At this scale, the concrete pad is as important as the tank. A 4,995-gallon vertical tank concentrates tens of thousands of pounds onto a 142-inch footprint, and an under-built or out-of-level pad is the most common and most expensive mistake at this size. Get the slab right before the tank ever arrives. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework. If this reservoir is part of a private fire-protection stack, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. Pairing this tank into a grey-water, rainwater, or HVAC-condensate reuse system is covered in our industrial water-reuse tank topology guide.
Fittings, freight, and ordering
Fitting size and placement are not listed in our catalog data for this tank, so read them off the technical drawing on this page or confirm them by phone before you plumb anything. This tank ships LTL freight from the Norwesco plant in Fairfield, TX, with the rate quoted live to your ZIP. It ships only from that single Texas origin, so freight scales with distance from Fairfield, and a 142-inch footprint makes this an oversized item that needs offload equipment and clear access at delivery. Get an exact number from our Freight Cost Estimator, or call 866-418-1777 and we will quote the run from Fairfield to your site and help confirm the pad, fittings, and offload plan before you order.
