The Snyder Industries 7900 Gallon HDPE Vertical Liquid Storage Tank is a Lincoln, Nebraska-built polyethylene tank engineered for high-volume water and liquid storage where you need real headroom and a footprint you can pad and plumb. Standing 177 inches tall on a 120 x 120 inch base, this is one of the larger single-tank water reservoirs in the catalog, molded in white HDPE with an ASTM-certified build and rated to a 1.9 specific gravity. If you have been searching for a vertical storage tank or a tall Snyder vertical tank for serious volume, this is the upper end of what fits on a single pad.
Will it work for your site?
This is a vertical storage tank with a true 7,900-gallon working capacity. Filled with water, the contents alone weigh 65,886 lb, so the tank, full water weight, and dead load drive your pad design from the start - this is not a tank you set on bare grade. The 120 x 120 inch footprint is what you size your concrete pad to. Rated to 1.9 specific gravity, this tank is built to hold liquids up to about 1.9 times the density of water - that is the 125,183 lb contents rating versus 65,886 lb for plain water. If you are storing brine, fertilizer solution, or other dense liquids, that SG headroom is exactly why you would pick this build over a water-only tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the tank suits your draw rate and refill cycle before you commit.
Fittings and access
The tank comes configured with a flange, an 18-inch PE threaded and vented fitting, and a manway with 15-inch access. The 18-inch PE threaded and vented fitting handles top-side venting - on a 177-inch tank, proper venting during fill and draw-down is what keeps you from pulling a vacuum on the wall. The 15-inch manway access is your entry point for interior inspection and cleaning, so confirm it suits your maintenance routine and any tank-cleaning gear before install. See the technical drawing on this page for exact fitting locations and elevations before you finalize your inlet, outlet, and overflow plumbing - fitting placement on a vertical HDPE tank this tall is what determines your usable draw-down and overflow routing, and it is the detail most buyers overlook until the tank is already on the pad.
Sizing and pad considerations
At 177 inches tall and fully loaded, this storage tank concentrates a large load over a 120 x 120 inch area. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground polyethylene tanks, and the HDPE wall-thickness and ASTM D1998 sizing piece explains where premature failures actually originate in tall vertical tanks. If this is going into fire-water or reservoir duty, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.

At 177 inches tall on a 120 x 120 inch base, this exceeds standard dock-height handling, so confirm your site has a crane or boom-truck for offload and adequate overhead clearance for the upright set, not just forklift access. Listed price is before freight; freight is quoted separately to your delivery ZIP.
