The Snyder Industries 500 Gallon Plastic Gravity Feed Tank System is a white high density linear polyethylene tank built for bulk water storage where you need elevated head pressure for gravity-fed distribution. It holds 500 gallons, stands 101 inches tall, and sits on a 66 x 60 inch footprint. At roughly 4,170 pounds full of water, it carries enough head height to feed downstream lines without a pump, which is why it shows up in searches for a 500 gallon tank used in rural water supply, irrigation feed, and reserve storage.
Will it work for your job
This is a tall tank: 101 inches of height over a 66 x 60 inch base. That geometry is what makes gravity feed practical, but it also means you need a level, fully supporting pad under the entire footprint, and you should account for the height when you plan the install location and any overhead clearance. The tank is molded from high density linear polyethylene with a specific gravity rating of 1.9, so the wall is rated to hold contents up to 1.9 times the weight of water. For plain water (1.0) that gives you a wide margin: the maximum rated contents weight is 7,923 pounds against roughly 4,170 pounds for a full load. That 1.9 rating is also the built-in headroom on this unit, so the same tank handles denser water-treatment solutions and heavier liquids up to a specific gravity of 1.9, not just plain water. Run your numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. See the technical drawing on this page for fitting locations and exact molded dimensions.

Pad and structural planning
A loaded tank concentrates a lot of weight on a small footprint, so the pad matters more than people expect. Before you pour, read our guide on concrete pad sizing for above-ground polyethylene tanks, which walks through the ACI 360R-10 framework. If this tank is going into a rural fire-water reserve role, our write-up on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For reclaimed or aggregated supply, the industrial water reuse tank topology guide covers quality-banded storage trains.
Freight and the mistake to avoid
The common error on a tall gravity-feed tank is treating the pad as an afterthought. A 7,923-pound rated load on a 66 x 60 inch footprint demands a flat, continuous, fully supporting base; a partial pad, a soft spot, or point contact can stress the wall over time. Confirm the pad spans the entire footprint and is level before you fill, and plan your outlet height and gravity-drop run first, since the head pressure you get is set by where the outlet sits relative to the equipment you are feeding.
This tank ships LTL freight from Marked Tree, AR, with the rate quoted live to your ZIP. Because it stands 101 inches tall on a 66 x 60 inch footprint, plan to have a forklift or equipment on site to offload it from the truck.
