The 1500 Gallon HDLPE Vertical Double Wall from Snyder Industries is a sodium hypochlorite containment tank built from high-density linear polyethylene, standing 77 inches tall on a 93-inch diameter footprint. The double-wall construction builds a secondary containment barrier into the tank itself, and the 1.9 specific-gravity structural rating is deliberate headroom for a chemical like bleach: at full water the tank carries roughly 12,510 lb, but it is engineered for rated contents up to 23,769 lb, well above sodium hypochlorite's working density. Empty weight is 930 lb, access is through an 18-inch lid, and maximum service temperature is 120°F (48°C). The tank carries certifications 2285, 2282, and 3492.
Will it work for your site?
Sizing is where most tank orders go wrong, so plan around the loaded weight, not the empty shell. That full 1.9 SG rating — 23,769 lb of rated contents versus 12,510 lb for water — is the number that drives your foundation. A tank this size wants a level, continuously supported pad rated for the full loaded weight; run the math with our Tank Sizing Calculator and read the concrete pad sizing framework before you pour. Confirm the 93-inch round footprint and 77-inch height against your doorway, containment berm, or slab. See the technical drawing on this page for the port and fitting layout.
The double-wall detail buyers miss
On a double-wall tank the usable volume is not the same as the nameplate gallons. Thermal expansion and the density of your stored contents both eat into what you can actually fill, and the interstitial space between the walls is containment, not capacity. The Snyder double-wall freeboard guide walks through the ASTM D1998 math so you size to the real working volume rather than the label.
The mistake to avoid: fittings and gaskets
For sodium hypochlorite service, compatibility is decided at the fittings, not the shell — bleach is hard on elastomers and hardware. This listing does not come with a pre-configured port and fitting package, so verify gasket and bulkhead-fitting materials against Snyder's chemical-resistance chart (concentration- and temperature-specific) and confirm the full fitting package with us at order. That one check is what separates a tank that lasts from a tank that leaks at the bulkhead.
Freight
This double-wall vertical tank ships LTL from its primary Snyder origin in Lincoln, NE, with Chowchilla, CA available as the West-coast alternate, and freight is quoted live to your ZIP rather than baked into the list price.
