The Enduraplas 2500 Gallon Vertical Water Storage Tank (SKU TC9589IW-GREEN) is a green polyethylene vertical tank built for bulk water storage — irrigation reserve, rural fire-water, and process-water service. It stands 89 inches tall on a 95 x 95 inch footprint, holding 2,500 gallons in a compact, self-supporting cylinder that fits a standard poured pad without the sprawl of a low-profile design. Full, it carries 20,850 pounds of water — that figure, not the empty shell weight, is what sets your pad and site engineering, and it is the number to hand your concrete contractor before anything gets set.
Will it work for your site?
This is a 2,500-gallon vertical bulk water tank, 89 in tall on a 95 x 95 in footprint, dimensions verified for this listing. Let the technical drawing on this page govern the exact outside diameter, fitting layout, and lid placement — confirm those against the drawing before you plumb it. The vertical geometry keeps the load footprint tight and the water column tall, which is what you want for gravity head off an elevated outlet or for feeding a booster pump. To size a reservoir against real demand — daily draw, refill rate, or fire-flow duration — run your numbers through the Tank Sizing Calculator and cross-check the method in the Tank Sizing Guide.
Pad and install
A vertical tank this size lives or dies on its foundation. The full water weight of 20,850 pounds bears on that 95 x 95 inch footprint, so the pad has to be flat, fully supporting under the entire base, and sized to the load. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework for exactly this case. Once it is set and plumbed, commission it properly — the hydrostatic test methodology for new-install acceptance covers water-fill discipline, pad-settlement monitoring, and fitting leak detection so you catch a problem before the tank is in service, not after.
Common use and the mistake to avoid
Buyers put 2,500-gallon vertical poly tanks to work as rural fire-water reservoirs, irrigation and haul-water storage, and industrial water-reuse holding — see fire-water reservoir design under NFPA 22 and the industrial water-reuse tank topology guide if that is your application. The mistake to avoid: this is a water storage tank. Do not press it into chemical service on the assumption that poly is poly. Chemical duty depends on resin grade and a specific-gravity rating this water tank does not carry — if you are storing anything but water, call us first and we will match you to a tank rated for the fluid.
This tank ships LTL freight, palletized and quoted live to your ZIP — at roughly 20,850 pounds full it moves as freight, not flat-rate parcel, so pricing is set per destination. Get a number in seconds with the Freight Cost Estimator or call 866-418-1777 and we will size the reservoir, confirm fittings against the drawing, and lock your delivery. Freight is quoted separately and is not included in the list price.
