The Snyder Industries 8750 Gallon HDPE Vertical Liquid Storage Tank is built for high-volume bulk water and liquid storage, where a single large footprint replaces a bank of smaller vertical tanks. It carries an 8,750-gallon capacity in a White polyethylene body, stands 146 inches tall on a 142 x 142 inch footprint, and is rated to a 1.5 specific gravity. If you have searched for an HDPE vertical storage tank at this volume, this is the size class that anchors a site's storage stack - roughly 11.8 ft square and about 12.2 ft tall, so confirm overhead clearance, gate width, and a level truck approach before delivery day.
Will this tank work for your job?
Specify around the weight, not just the gallons. Filled with water (SG 1.0), this tank holds 72,975 lb of contents; at its full 1.5 SG rating the contents alone reach 109,462 lb. That number drives everything underneath the tank - the pad, the ring, and the soil bearing. One trap to close before you pour: foundation load equals contents weight (up to 109,462 lb) PLUS the empty tank shell weight, and the shell weight is not listed here, so pull it from the technical drawing on this page or from Snyder before you size the pad and the offload rig. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the capacity and headspace work for your draw-down and fill cycle before you commit to a pad pour.
Fittings and access
This tank is configured with the following fittings - check each against your plumbing plan:
- Flange - port size and elevation not listed in the spec sheet
- Flat fitting at 2.5 degrees - low on the sidewall for outlet/drain service
- 18-inch PE threaded/vented fitting - the one stated-size port on this listing
- Flat fitting at 92.5 degrees - sits high on the sidewall, which changes how you route overflow and vent
- S.U.M.O. fitting - Snyder's self-aligning/sealing outlet; size not listed
- Bulkhead - port size not listed
- Manway with 15-inch access opening - determines whether a person or your cleaning gear can reach inside for inspection and service
Outlet, flange, S.U.M.O., and bulkhead port sizes and elevations are not stated on this listing - read them off the technical drawing on this page or call 866-418-1777 to confirm before you plumb the site. The 92.5-degree flat fitting in particular sits high on the wall, so route the outlet and overflow off the drawing, not off assumptions.
The mistake to avoid: what the 1.5 SG rating does and does not clear
The most common error at this size is treating the 1.5 SG rating as headroom you can ignore. The rating means the tank wall is built for liquids up to 1.5 times the density of water - it does not mean you can fill past the line or skip a foundation engineered for the full 109,462 lb. Just as important, SG 1.5 is a structural wall rating only: it covers water and most density-driven liquids up to 1.5x water, but the fittings, gaskets, and chemical resistance are not certified by this listing. If you are storing anything other than water or fire-water, confirm gasket material and chemistry against the technical drawing and Snyder before service - do not assume the wall rating clears the chemistry. For density-driven and fire-water service, the HDPE wall-thickness and ASTM D1998 sizing discussion explains why the vapor-saturated headspace - not the liquid side - is where premature failures start, and the concrete pad sizing guide walks the ACI framework for a tank of this mass. For fire-protection storage, the fire-water reservoir design guide covers NFPA 22 sizing discipline.
This tank ships LTL freight from the Snyder plant in Lincoln, NE, and freight is quoted live to your ZIP - get your number with the Freight Cost Estimator or call 866-418-1777 to lock in delivery to your site. An 8,750-gallon vertical tank is an oversized LTL load, so plan for offload equipment rated to the empty tank weight and a clear, level approach for the truck.
