The Snyder Industries SII-WG81 is a 5000 gallon vertical water storage tank in green polyethylene, measuring 102 inches in diameter and standing 155 inches tall. A vertical poly tank of this size seats on a 102 x 102 inch pad envelope, so plan for the round body inside that square footprint. Its specific gravity rating of 1.0 tells you exactly what it is engineered to hold: water and other contents at a specific gravity up to 1.0. This is a dedicated water storage tank, not a chemical tank, and the SG 1.0 rating is the number that keeps you honest about that.
Will it work for your site
Filled to capacity with water, this tank carries 41,700 pounds of contents. That full-water weight is the single most important number for planning your foundation. A 5000 gallon vertical storage tank concentrates that load on a compact 102 inch circle, so the pad underneath has to be engineered, level, and fully supporting the base. Review our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide before you pour, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm this vertical tank fits your volume and space. After install, our hydrostatic test methodology guide walks the water-fill acceptance and pad-settlement check.
Fittings and access
The tank comes configured with a bulkhead fitting package sized for real plumbing: a 2 inch standard polypropylene bulkhead with an EPDM gasket, a 1-1/2 inch polypropylene eco-bulkhead with a textured EPDM seal, a flange, and a 2-3 inch S.U.M.O. fitting for flexible outlet placement. The wetted seals are EPDM and the bulkhead bodies are polypropylene, which is correct for water service; match your field-plumbing hardware to EPDM gaskets and the bulkhead threads. Top access is through an 18 inch polyethylene manway with a 4 inch vent and tie-down. On a tank this tall, keep that 4 inch vent clear at all times so a fast draw cannot pull a vacuum and collapse the tank, or pressurize it on a fast fill. Confirm the fitting layout and outlet heights against the technical drawing on this page before you plumb.
Freight and how to order
This vertical water storage tank ships empty by LTL freight from the Snyder plant in Marked Tree, Arkansas, and freight is quoted live to your ZIP code rather than included in the list price. The 41,700 pound figure is field-filled water weight, not the shipping weight, so you are quoting an empty poly tank. Because this is a 155 inch tall unit, delivery is a curbside LTL drop and you will want to plan offloading in advance. Get a real number with our Freight Cost Estimator, or call 866-418-1777 and we will quote the freight and confirm lead time from Arkansas to your delivery point.
