The Snyder Industries 550 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 550-gallon polyethylene vertical storage tank built for bulk water holding and long-service storage where durability matters. It stands just 47 inches tall on a wide 64 x 64 inch footprint, and its black resin and 1.9 specific gravity rating give it real structural margin over the lighter-duty tanks that share this profile. If you are shopping vertical storage tanks and want a black tank that holds up, this Snyder answers the three questions that matter: will it hold your water, how does it ship, and what will trip you up if you order in a hurry.
Will it work for your job
At 550 gallons this tank carries roughly 4,587 pounds when full of water. The 1.9 specific gravity rating is already the heavy-duty rating for this line, giving a maximum rated contents weight of about 8,715 pounds. That is durability headroom, not a restriction: you are getting a wall engineered well beyond plain water service, so the tank has margin for long-term storage, heavier water-adjacent solutions, and demanding sites. The low 47-inch height on a 64 x 64 inch base is a genuine advantage worth naming: it slips under low roof lines and into height-restricted pump houses and enclosures, and the wide base keeps the center of gravity low to reduce tip risk on a pad or skid. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 550-gallon size fits your fill-and-draw cycle before you buy.
Fittings and access
The tank comes configured with a flange, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access for cleaning and inspection. It also carries two 16 x 16 inch flat fitting pads for adding outlets or bulkhead fittings where your plumbing needs them. The vented lid matters on a closed vertical tank: it lets the shell breathe as you fill and draw so you do not pull a vacuum or pressurize it. The compatibility step people miss is the gasket: any bulkhead fitting you install on a flat pad needs a gasket matched to your stored liquid, so confirm gasket material along with port thread size against the technical drawing on this page before you plumb the installation.
Freight and how to order
This is an LTL freight item, not a parcel shipment, so plan for a truck delivery. It ships from the nearest Snyder plant to your delivery ZIP, either Lincoln, NE or Chowchilla, CA, and freight is quoted live to your address rather than bundled into the list price. Run your ZIP through the Freight Cost Estimator for a rate to your address, or call 866-418-1777 and we will quote it by phone. Two things to get right before ordering: size the pad for the load, not just the empty tank, because a full tank puts about 4,587 pounds of water (up to 8,715 pounds at the rated 1.9 specific gravity) onto the base, and confirm your outlet and manway needs against the drawing so you are not cutting ports in the field. If you are pouring a base for it, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework, and for rural or remote water holding the fire-water reservoir tank design guide covers sizing discipline for a tank this size. Questions on fit or freight, call 866-418-1777.
