The 3900 Gallon XLPE Vertical Liquid Storage Tank from Snyder Industries is a cross-linked polyethylene vertical storage tank built for high-volume water and liquid storage. It stands 163 inches tall on a 90 x 90 inch square footprint, holds 3,900 gallons, and carries a 1.9 specific-gravity rating - meaning it's built to hold liquids up to 1.9 times the density of water. For plain water duty (water is 1.0 SG), that 1.9 rating is genuine over-spec: you get heavy-liquid headroom at no configuration change. The white cross-linked (XLPE) wall is a molded, single-material shell rated to ASTM standards, and the tank's full specs are documented in the technical drawing on this page.
Will it work for your site?
Sizing is where most orders go wrong, so run the numbers before you commit. Filled with water, this tank carries roughly 32,526 pounds; at its full 1.9 SG rating the contents can reach about 61,799 pounds. That load, plus the tank's own weight, has to sit on a pad engineered for it - and that same weight is what drives LTL cost, so pull a number early with the Freight Cost Estimator. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm capacity against your draw and refill cycle, and read our concrete pad sizing guide before you pour a foundation for a tank this heavy. As a large vertical vessel it also suits grey-water, rainwater, and HVAC condensate aggregation - our industrial water-reuse topology guide maps out those storage trains.
Fittings and access
The tank is configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access for interior inspection and cleaning, a 10-inch x 12-inch sized S.U.M.O. outlet, and a separate flat, integrally-molded S.U.M.O. mounting pad for a self-mounting fitting. The 15-inch manway access matters if you plan to inspect, clean, or service the tank in place. Because polyethylene bulkhead fittings seal on a gasket rather than thread tape, verify gasket and thread size against the drawing and confirm your pump, screen, or float hardware matches the threaded and S.U.M.O. outlet positions before you plumb the site.
The mistake to avoid
Don't underspec the wall for the vapor space. On tall vertical polyethylene tanks the headspace - not the liquid side - is where premature failures start, which is why the 1.9 SG XLPE construction and ASTM D1998 sizing logic matter here. Our guide on wall thickness at the vapor-saturated headspace explains what liquid-side inspections miss. For rural fire-water and reservoir duty, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
