The Snyder Industries 300 Gallon Black Vertical Water Storage Tank holds a full 300-gallon water column in a compact 46-inch square footprint, standing 48 inches tall. It is molded from black polyethylene and rated to a 1.0 specific gravity, which matches plain water and other contents no heavier than water. If you need bulk water on hand for livestock, irrigation, rainwater capture, a fire-protection reserve, or a water reuse train, this is a straightforward vertical storage tank that sits on a small pad and holds a full water column without sprawling across your site.
Will it work for your site
The 1.0 specific gravity rating is the number that matters most here. At 1.0 the tank is built for water and water-weight liquids; it is not rated for heavier chemical contents. Filled to capacity, 300 gallons of water weighs about 2,502 pounds, so plan the pad and base for that load - a level, fully supported surface under the entire 46.0 x 46.0 footprint carries the weight safely. The vertical profile keeps the footprint small while giving you the full 300 gallons in a 48-inch-tall body, which is what most buyers searching for a 300 gallon vertical storage tank are after when ground space is tight.
Fittings and access
The tank comes plumbed for real-world use. You get two independent bulkhead outlets - a 1-1/2-inch polypropylene bulkhead with an EPDM gasket and a 2-inch standard polypropylene bulkhead with EPDM - plus a separate flanged port, so you can run a fill line, a draw line, and a third connection without adding tappings in the field. Both bulkheads pair UV-stable EPDM gaskets with polypropylene bodies, materials that are inert in water service and appropriate for an outdoor black tank. Up top is an 18-inch polyethylene manway assembly with a 4-inch vent and an integrated tie-down. The 4-inch vent lets the tank breathe during fast fill and draw-down cycles - relevant for irrigation and fire-reserve duty where flow rates are high - and the manway gives you room to fill, inspect, and clean the interior. For exact fitting placement and elevations, see the technical drawing on this page.
Sizing the right tank
The same 300 gallons can be molded in different shapes. This tank's 46 x 46 x 48 body sits between a wider-shorter and a taller-narrower configuration, so footprint and fill height are the trade-off to weigh. Our Tank Sizing Calculator and Tank Sizing Guide walk through usage, refill cadence, and footprint against headroom. For alternative 300-gallon configurations, compare the wider-and-taller 300 gallon black tank guide and the tall-and-narrow 300 gallon black tank guide so you pick the footprint that fits your pad. If you are designing a rural fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and our water reuse topology guide covers grey-water, rainwater, and HVAC condensate aggregation.
