The Snyder Industries 200 Gallon HDPE Vertical Liquid Storage Tank is a 200-gallon white polyethylene vertical tank built and certified to ASTM standards, made for clean water and general liquid storage where you need a compact footprint and a verified spec sheet. It stands 59 inches tall on a 36 x 36 inch base, so it fits through standard gate openings and tucks into a corner of a pump house, equipment yard, grow room, or rural fire-water reservoir without eating floor space. As a 200 gallon vertical storage tank, it gives you straightforward gravity-fed or pump-fed water storage in a shape that's easy to plumb and easy to inspect.
Will it work for your application
The tank holds 200 gallons in a 36 x 36 inch footprint and a 59-inch overall height. Filled with water, it carries roughly 1,668 pounds of contents, so plan your pad accordingly — a level, fully supporting concrete or compacted base under the entire bottom, not blocking or partial cribbing. This HDPE vertical tank is rated to a 1.9 specific gravity, which means the wall is built to safely hold liquids heavier than water, up to a maximum rated contents weight of about 3,169 pounds. For plain water you can plan on the full 200 gallons; for denser or thermally-expanding liquids, leave freeboard per ASTM D1998 so usable volume runs below nameplate — run the numbers first with the Tank Sizing Calculator and the Tank Sizing Guide so the 200-gallon body matches your real draw-down and refill cycle. If your liquid is dense enough to need containment or freeboard math, the Snyder Captor double-wall freeboard guide walks through how density and thermal expansion eat into the volume you can actually use.
Fittings and configuration
This tank's fitting configuration — lid, inlet, and outlet — is shown on the technical drawing on this page rather than in a separate spec list, so confirm the bulkhead and vent layout against your plumbing before you order. Match the drawing's fittings and gasket arrangement to your draw and return lines so nothing has to be re-drilled on site. If anything on the drawing is unclear, call us at 866-418-1777 and we'll walk through it with you before the tank ships.
The mistake to avoid
The most common error on a vertical tank this size is the foundation, not the plumbing. The pad has to support the worst case the tank is rated for — up to the 3,169 lb maximum rated load, not just the 1,668 lb water weight — and that load concentrates straight down on the 36 x 36 inch footprint. Set it on a surface that fully supports the entire base. A tank sitting on uneven ground or spanning a gap will flex the bottom knuckle and shorten its life, regardless of how good the resin is. It's also worth understanding where polyethylene tanks actually wear: the wall behaves differently at the vapor-saturated headspace than down in the liquid, which is why the HDPE tank wall-thickness and ASTM D1998 sizing guide is worth a read before you put it into long-term service. For a full walkthrough of this exact model, see the 200 Gallon Vertical Liquid Storage Tank buyer's guide, and check the technical drawing on this page for the dimensioned layout.
