The Enduraplas TC4594IW-GREEN is a 550-gallon vertical water storage tank standing 94 inches tall on a 45 x 45-inch footprint, molded in green polyethylene for above-ground bulk water service. It suits the jobs where you need a tall, small-footprint column of water in a fixed spot: rural fire-water reservoirs, rainwater and grey-water reuse trains, non-potable haul-and-store, and process makeup water. The vertical profile gives you real capacity without eating up floor space, and the closed top keeps stored water clean between fills.
Will it work for your site
Capacity is 550 gallons in a vertical storage configuration. Verified dimensions are 94 inches tall by 45 inches in both width and length, so plan overhead clearance for the fill fitting and any level gauge before you set it. Full of water this tank carries roughly 4,587 pounds, and that is the number that governs your pad and your rigging, not the empty shipping weight. This is a water-service tank; we do not have a published specific-gravity rating on file for it, so for any fluid heavier than water call us at 866-418-1777 before you order. Use the Tank Sizing Calculator and the Tank Sizing Guide to match this 550-gallon body to your draw-and-refill cycle.
Set it on a real foundation
A tall vertical tank loaded to 4,587 pounds needs a flat, fully supporting base. Spread over the 45 x 45-inch footprint, that full-water load works out to roughly 326 pounds per square foot of bearing pressure, so set the tank on a level concrete pad or compacted engineered surface that carries the entire footprint edge to edge, never on isolated blocks or an unsupported deck. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework, and once the tank is installed the hydrostatic test methodology shows how to water-fill for acceptance and monitor pad settlement. For fire-protection duty, the NFPA 22 sizing and freeze-protection guide covers reservoir design for remote and cold-climate sites, and the water-reuse topology guide covers grey-water, rainwater, and condensate aggregation trains.
The mistake to avoid
The most common error on a 94-inch vertical tank is under-building the base and overhead. Because the tank stands nearly eight feet tall, a small tilt at the pad becomes a large lean at the top, and the full-water load concentrates that stress. Get the pad dead level and fully bearing before your first fill, and leave headroom for the top fittings. Review the technical drawing on this page and confirm outlet and fitting locations with us at 866-418-1777 before you plumb, so your lines land right on the first try.
This tank ships LTL freight, quoted live to your ZIP through our Freight Cost Estimator or by phone at 866-418-1777. Because it is a tall, rigid poly tank, freight moves palletized and the rate depends on your distance and site access. Get your ZIP-specific number from the estimator, then call us at 866-418-1777 if you want help matching the right water tank to your site.
