The Snyder Industries 4900 Gallon ASTM XLPE Black Vertical Storage Tank is a large-format crosslinked polyethylene tank rated to a 1.5 specific gravity, giving you real headroom for dense contents rather than water alone. Standing 202 inches tall on a 90 x 90 inch footprint, this is a heavy-duty vertical storage tank built in crosslinked linear polyethylene (XLPE) and finished in black, which cuts light transmission and suppresses algae growth in water and fluid storage. If you are comparing XLPE storage tanks for bulk vertical service, this is one of the workhorse Snyder sizes.
Will it hold what you need?
At 4,900 gallons, a full load of water weighs roughly 40,866 pounds, and at the tank's full 1.5 specific gravity rating the contents can reach about 61,299 pounds. Plan your pad and structural support around the heavier number if you intend to store anything denser than water, since the 90 x 90 inch footprint concentrates that load and a properly engineered foundation matters. One point buyers miss: ASTM D1998 freeboard means your usable volume is less than the 4,900-gallon nameplate once you account for expansion and fill headroom, so size to usable capacity, not the label. Our Snyder freeboard sizing guide walks through the real number. Then use the Tank Sizing Calculator and Tank Sizing Guide to match capacity to your draw-down and refill cycle, and review our concrete pad sizing framework before you pour.
Fittings and access
Per the technical drawing on this page, this tank is configured with a flange, an 18-inch PE threaded and vented fitting, a manway with 15-inch access, a 2-3 inch S.U.M.O. fitting, a 12 x 14 inch fitting, and a flat fitting landing for adding your own outlet. The 15-inch manway access supports inspection, cleaning, and maintenance on a tank of this height. Confirm each fitting size and position against the drawing before you plumb the installation, and match each bulkhead fitting and its gasket material to your stored fluid and to the 1.5 specific-gravity head pressure before you order fittings or plumb the tank, since outlet placement drives your manifold design.
Sizing for the job
This size suits fire-water reservoirs, bulk process water, industrial water reuse, and rainwater aggregation trains. If you are speccing it for private fire protection, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate storage, see our industrial water reuse tank topology guide.
This tank ships LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP. Get a number in seconds with our Freight Cost Estimator, or call 866-418-1777 to talk through fittings, foundation, and delivery. A common delivery mistake is under-preparing the offload: confirm you can handle a roughly 202-inch (nearly 17-foot) tank on arrival. It ships empty, so your offloading equipment needs to clear the height, not the filled weight, which only applies once the tank is on its pad.
