The Snyder Industries 4900 Gallon ASTM Black Vertical Storage Tank is a large-volume polyethylene vertical tank built to ASTM standards and molded in black to shield stored water from UV and algae growth. It stands 202 inches tall on a 90 x 90 inch square footprint, so before you commit, confirm you have the vertical clearance and a level pad that can carry the load. Filled with water it weighs roughly 40,866 lb, and at its 1.5 specific-gravity rating it is engineered to hold contents up to about 61,299 lb. Those two numbers drive your foundation more than anything else on this page.
Will it work for your site?
This is a vertical storage tank for bulk water and comparable liquids up to a 1.5 specific gravity. The molded-in ports shown on the technical drawing on this page give you room to plumb fill, vent, outlet, and inspection access without cutting blind into the wall:
- Flange fitting
- 18" PE threaded/vented fitting
- Manway with 15" access
- Two 2–3" S.U.M.O. fittings
- 12" x 14" fitting
- Flat fitting pad (un-drilled — locate a custom bulkhead exactly where your layout needs it)
The S.U.M.O. and 12" x 14" openings are not plumb-ready out of the box; each needs a matching gasketed bulkhead fitting (EPDM gaskets for water service) sized to the port to seal. We can include the correct bulkhead fittings and gaskets on your quote — just tell us your outlet plan. The 15" manway access matters for cleaning and interior inspection on a tank this size, so plan your ladder and platform around it. Water only approaches 1.5 SG at extreme dissolved-solids loads, so most water and many denser solutions stay well inside this tank's rating — but verify your fluid's specific gravity before ordering rather than assuming.
Sizing, freeboard, and foundation
At 4,900 gallons this is a serious reservoir, but remember that nameplate is measured to overflow — the 18" vented fitting and manway sit above working level, so your real usable draw is less once you leave freeboard. Size to actual usable volume using our Tank Sizing Calculator and Tank Sizing Guide, and the Snyder Captor freeboard-sizing guide walks through how much you can actually use. If this is destined for rural fire protection, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection. The single biggest mistake on a tank this heavy is an undersized or unlevel pad, so review our concrete pad sizing guide before you pour. If you need secondary containment without an earthen berm, ask us about a double-wall Snyder Captor option instead of this single-wall tank.
Freight and ordering
This Snyder vertical tank ships LTL freight from the Snyder plant in Lincoln, Nebraska, with freight quoted live to your ZIP rather than bundled into the list price. This is an oversized load: plan for forklift or crane offload and clear overhead room for the 202" height at delivery, since a site that can't receive it is the number-one freight failure. Get an exact number through our Freight Cost Estimator, or call 866-418-1777 to schedule delivery of your black vertical storage tank. Confirm your specific gravity, fitting layout, and pad first, and our team will help you finalize the rest.
