The Snyder Industries 8000 Gallon Vertical Liquid Storage Tank is a large-format white HDPE reservoir built for stationary bulk water storage. It molds from High Density Linear Polyethylene, stands 184 inches tall on a 120 x 120 inch footprint, and carries a 1.5 specific gravity rating - the structural ceiling that sets the maximum contents weight this vertical storage tank is designed to hold without thinning the wall faster than the design allows.
Will it work for your site
At 8,000 gallons, plan your pad and your weights before anything else. Full of water this tank loads roughly 66,720 lb on the slab; at its 1.5 SG rating the maximum rated contents weigh about 100,080 lb, so the foundation has to carry the heaviest liquid you intend to store, not just water. That 1.5 rating is also a reason to choose this unit over a 1.0-rated, water-only vertical: it gives you weight headroom to store denser-than-water aqueous solutions later - up to the 100,080 lb ceiling - without re-buying a tank. The 120 x 120 inch footprint is square, which simplifies a poured pad. Standard fittings on the white tank, per the technical drawing on this page, include an 8 inch x 7 inch flat-area fitting, a 3 inch polypropylene bulkhead fitting with an EPDM gasket, a 20 inch vented manway, and stainless lid fasteners (#9 stainless screws) so the access hardware won't corrode in the humid headspace. The Tank Sizing Calculator and our Tank Sizing Guide walk through draw-down and capacity so an 8,000 gallon HDPE tank isn't oversized for the duty.
Chemical compatibility
This is a High Density Linear Polyethylene tank rated to 1.5 specific gravity, which covers water and most aqueous solutions up to that density. The compatibility lever buyers miss is the gasket: the 3 inch bulkhead fitting ships with an EPDM elastomer seal, which suits water and many water-based services but is the wrong seal for petroleum or oil-based media - and gaskets are swappable to match the stored fluid. Match the elastomer to your liquid, and always verify any non-water service against the OEM chemical-resistance chart at the relevant concentration and temperature before you commit. Start with the chemical compatibility tool.
Common use and the mistake to avoid
This is a workhorse for rural and remote water reservoirs, including private fire-protection supply. If that is your use, read Fire-Water Reservoir Tank Design for NFPA 22 sizing discipline and cold-climate freeze protection - both change how you size and where you site the tank. The mistake we see most on a tank this large is treating the 1.5 SG rating as a license to fill it with anything heavy: the rating sets the contents-weight limit, but it does not waive the foundation engineering. Two practical checks before you pour: verify the 8 inch x 7 inch flat-area fitting location on the drawing against your plumbing run so the outlet lands where your run needs it, and confirm the 20 inch manway's integral vent is clear - that vent prevents vacuum collapse on fast draw-down or pump-out, a real failure mode on tall verticals. The other thing operators overlook is the upper wall: premature failures on tall vertical tanks tend to start in the vapor-saturated headspace above the liquid line, which routine liquid-side inspection misses. The HDPE Tank Wall Thickness guide explains the ASTM D1998 sizing logic behind it.
Freight and ordering
This Snyder vertical storage tank ships LTL from the Merced, California plant, the named production point for this SKU, with freight quoted live to your ZIP - an 8,000 gallon tank moves on its own truck, so the delivery point and access matter. Get a real number before you order with the Freight Cost Estimator, or call 866-418-1777 and we will work the route and the offload with you. Listed price is before freight.
