Snyder Industries 7000 Gallon ASTM XLPE Black Vertical Storage Tank

The Snyder Industries 7,000 gallon vertical storage tank is a black crosslinked linear polyethylene (XLPE) tank molded to ASTM standards for heavy bulk water and high-density liquid storage. It stands on a 142-inch diameter with a 122-inch overall height, so its footprint is the bounding box of that 142-inch body. The 1.5 specific-gravity rating gives you real headroom above plain water. If you are sourcing a vertical storage tank in this size class, this is the black XLPE workhorse that anchors bulk water, fire reserve, and industrial storage installations.

Will this tank work for your site?

Capacity is 7,000 gallons in a single vertical body. Filled with water, contents weigh 58,380 lb, and that number approaches six figures once tank weight and appurtenances are added, so plan the pad accordingly. The tank is rated to a maximum contents weight of 87,570 lb, which is 7,000 gallons at the full 1.5 specific gravity. That is a hard ceiling: divide your liquid's specific gravity into that figure to confirm fit. A liquid heavier than 1.5 SG exceeds the wall design and should not go in this tank. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm this size matches your throughput and pad plan before you order.

Fittings and access

The technical drawing on this page details the outlet package:

• Bolted flange connection
• 12" x 28" fitting with S.U.M.O. reinforcement
• Second reinforced S.U.M.O. fitting
• 18" polyethylene fitting that is both threaded and vented (integral venting for a water or fire tank)
• Manway with 15" access for interior entry and cleaning

Bolted flange and manway connections seal to your supplied gaskets, so match the gasket elastomer to your stored liquid. Confirm your fill, draw, and vent points against the drawing before you set the tank; a vertical tank this large is not something you want to re-plumb after it is standing.

The mistake to avoid

Do not underestimate the foundation. A level, continuously supported concrete pad is non-negotiable for a tank carrying tens of thousands of pounds; a soft or uneven base is the most common cause of premature vertical-tank failure. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. If you are sizing this tank for rural fire protection, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
