The Snyder Industries 4500 Gallon ASTM Black Vertical Storage Tank (SKU 7000400N49) is a full-size bulk water tank molded from polyethylene with a 1.5 specific gravity rating, which is the ceiling for this SKU and gives it real headroom for water and light-density liquids up to that SG. It stands 91 inches tall on a 143 x 143 inch footprint, so plan the pad for that full square footprint before delivery. This is a serious-volume tank: filled with plain water it carries roughly 37,530 lb, and at its maximum rated 1.5 SG contents it can hold about 56,295 lb. Every one of those pounds rides on the pad and the ground beneath it, which is why the base has to be right from day one.
Will it work for your site?
At 4500 gallons this vertical storage tank suits rural fire-water reserves, irrigation, rainwater capture, and process water where you need high-volume storage and have the ground space for its 143 x 143 inch footprint. The tank comes with a flange fitting, an 18" PE threaded/vented fitting, and a manway with 15" access for interior entry and cleaning; the exact port sizes and placements are shown on the technical drawing on this page, so match your bulkhead and flange adapters, and their gaskets, to those ports before you order, since a mismatched gasket is the usual leak point on flanged poly connections. Because the black polyethylene blocks light, it suppresses algae growth better than a translucent tank in outdoor water service. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm this volume fits your demand and refill cycle, and if you are aggregating grey water, rainwater, or HVAC condensate, our Industrial Water Reuse Tank Topology guide maps how a tank this size fits a quality-banded storage train.
Pad, weight, and the mistake to avoid
The single biggest error on a black vertical tank this size is an undersized or unlevel base. If you are storing plain water at 1.0 SG, size the foundation to the 37,530 lb case; the 56,295 lb figure assumes contents at the full 1.5 SG rating, so reserve that headroom only if you are actually filling with a heavier liquid. Either way the tank needs a flat, fully supporting foundation across the entire 143 x 143 inch footprint. Review Concrete Pad Sizing for Above-Ground Polyethylene Tanks before you pour. If this is a fire-protection reservoir, our Fire-Water Reservoir Tank Design guide walks the NFPA 22 sizing and freeze-protection details.
Freight
This tank ships LTL freight from the Snyder plant in Chowchilla, CA, and freight is quoted live to your ZIP code, never bundled into the list price. West Coast destinations will generally quote shorter, cheaper LTL than East Coast ones given the single California origin, so get your exact number with the Freight Cost Estimator or call 866-418-1777 and we will confirm the nearest shipping point, transit time, and any offload requirements for a load this size. Because it moves as an oversized LTL shipment, staging a forklift or crew for offload before the truck arrives saves both time and money.
