The Snyder Industries 1000 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene vertical storage tank rated for liquids up to a 1.5 specific gravity, standing 89 inches tall on a 60 x 60 inch footprint. If you are sizing a vertical tank for water, rainwater capture, fire-water reserve, or general liquid holding, this is a straightforward 1000 gallon HDPE storage tank built to ASTM standards and shipped from Snyder's Chowchilla, California plant.
Will it work for your site?
Filled with plain water, this tank carries roughly 8,340 pounds of contents; at its full 1.5 SG rating it is engineered to hold up to 12,510 pounds. That spread matters when you pour a pad or set a base: size the foundation to the maximum rated load, not the water weight, so you keep margin if you ever store something denser than water. The 60-inch square footprint keeps the tank compact for its volume, and at 89 inches tall it sits well within most barn bays and outbuildings. Fittings include a flange, an 18-inch PE threaded and vented top fitting, and a manway with 15-inch access — that manway is a real maintenance feature, letting an operator reach inside for periodic inspection and cleaning, which matters on water and fire-reserve service where you actually need to check the tank over its life. Exact fitting locations and elevations are shown on the technical drawing on this page; confirm your plumbing and overflow heights against it before you set the tank. If you are still narrowing capacity, run your numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
The mistake to avoid
The most common error on a tank like this is treating the 1.5 specific gravity rating as a "store anything" license. The rating tells you the wall is built to carry contents up to 1.5 times the density of water — it says nothing about chemical compatibility of the HDPE resin or, just as important, the gasket and thread-seal materials on the flange, the 18-inch threaded fitting, and the manway. For water and water-like service this 1000 gallon vertical tank is exactly right. For a denser or reactive liquid you are looking at a different configuration: verify those specific gasket materials against the chemical, and consider a chemical-rated or double-wall containment setup instead of assuming this unit covers it. Our guide on Snyder Captor double-wall freeboard sizing per ASTM D1998 walks through that upgrade path honestly. The second mistake is under-building the foundation by sizing it to water weight instead of the 12,510-pound maximum rated load. For how wall thickness and ASTM D1998 sizing logic drive long-term tank life, our guide on HDPE tank wall thickness and ASTM D1998 sizing is worth reading before you buy.
Fire-water reserve service
If you are siting this as a private fire-water reservoir for a rural or remote property, capacity and freeboard sizing follow their own discipline. Our guide on fire-water reservoir tank design and NFPA 22 sizing covers how a polyethylene tank like this fits the private fire-protection stack, plus freeze protection for cold-climate sites. The 15-inch manway access is useful here too, since fire-reserve tanks need periodic inspection to stay service-ready.
