The Snyder Industries 300 Gallon Black Vertical Water Storage Tank holds 300 gallons in a compact vertical footprint - 36 by 36 inches square, standing 82 inches tall. It is molded from polyethylene and rated at 1.0 specific gravity, built for plain water service: rainwater catchment, hauled water, well-supply buffering, irrigation reserve, and emergency or fire-water reserve. The black walls block sunlight, which keeps algae from growing in stored water - a practical reason to choose black over a translucent tank for outdoor placement. This tank ships LTL from Merced, CA, so price your delivered freight on the Freight Cost Estimator before you commit.
Will it work for your site?
Plan your pad and supply lines around real numbers. Filled to 300 gallons, water alone weighs 2,502 pounds, and that figure is also the maximum rated contents weight - so a level, compacted base that fully supports the entire 36 x 36 inch footprint is not optional. Set this tank on continuous support, never on blocks or a partial ring. At 82 inches tall the top fitting sits well overhead, so confirm fill access and overhead clearance before delivery. If you are still sizing the job, run your draw rate and refill interval through the Tank Sizing Calculator or read the Tank Sizing Guide to match a vertical storage tank to your demand.
Fittings - match your plumbing before you order
The technical drawing on this page shows the fitting layout. Confirm outlet location and thread against the drawing before you buy valves or pipe so your manifold lines up the first time:
- 1-1/2 inch polypropylene Eco bulkhead fitting with EPDM seal
- 2 inch standard polypropylene bulkhead fitting with EPDM seal
- Flange
- 10 inch polyethylene lid with tie
Both bulkhead outlets seal with EPDM gaskets, which are rated for plain water. If you ever change the service fluid, confirm gasket compatibility first - EPDM is not universal.
The mistake to avoid
The most common error on a 300 gallon tank this tall is underbuilding the base. With more than 2,500 pounds bearing on a 36-inch square, an uneven or undersized pad loads the tank wall unevenly and shortens its life. Build a flat, full-footprint base rated for the full water weight. The second error is service mismatch: this tank carries a 1.0 specific gravity rating, meaning it is sized for water, not heavier fluids. Do not store a product denser than water in it - if you need to store something heavier, this tank is not rated for it, and you should look to a tank with a higher specific-gravity rating instead.
Putting it to use
This is a workhorse size for households and small operations that need real water storage without a wide footprint - rainwater collection, a buffer between a low-yield well and demand, livestock and irrigation supply, or a private fire-water reserve. For fire-protection planning, see our guide on fire-water reservoir tank design for rural and remote sites. If you are aggregating grey water, rainwater, or HVAC condensate for reuse, our overview of industrial water reuse tank topology covers quality-banded storage trains. If this footprint is not quite right, compare two alternate 300-gallon configurations: a wider, shorter 300 gallon black tank and a taller, narrower 300 gallon black tank - same capacity, different height and diameter to fit different spaces.
This 300 gallon vertical water storage tank ships LTL freight from Merced, CA, with freight quoted live to your ZIP. Get your number on the Freight Cost Estimator or call 866-418-1777. Because LTL cost is driven by distance to the destination, buyers nearest the Merced plant generally see the lowest freight on this tank.
