The Snyder Industries 300 Gallon Black Vertical Water Storage Tank is a 300-gallon polyethylene vertical storage tank built for water storage on a compact 35-inch by 35-inch footprint. Standing 78 inches tall in black polyethylene, it answers the three things that matter before you buy: whether it fits your site and load plan, what it takes to get it to your ZIP, and the one detail that trips people up on a tank this size.
Specifications and fittings
This is a vertical water tank rated for a specific gravity of 1.0, the correct rating for water service. Filled to capacity, it holds 2,502 pounds of water, so plan your pad, stand, or slab around that loaded weight rather than the empty tank weight. The footprint stays at 35.0 x 35.0 inches and the tank rises to 78 inches, so confirm your door, gate, and ceiling clearances before delivery. Up top, it comes with an 18-inch polyethylene manway with a 4-inch vent and tie-down provision. Keep that 4-inch vent clear at all times: on a 300-gallon tank, a fast draw or fast fill can pull or push enough air to deform the shell if the vent is blocked, and the integrated tie-down provision lets you strap the lid against wind uplift on an empty tank. For plumbing, use the 2-inch standard polypropylene bulkhead with EPDM seal as your primary fill or drain and the 1-1/2-inch polypropylene Eco bulkhead with EPDM seal for a secondary line, overflow, or recirculation tap. Both seals are EPDM, which suits water service, but match your mating fittings and gaskets to the EPDM elastomer and the polypropylene body thread so you do not create a material-mismatch leak. The technical drawing on this page also shows a flange detail and an additional bulkhead location, so confirm on the drawing whether that port needs to be plugged or plumbed for your run, and verify all fitting heights and positions match your layout.
Sizing it right
At 300 gallons, this tank sits in a popular range for rural water storage, fire-water reserve, water hauling, and water reuse setups, and it is one of several 300 gallon vertical storage tank configurations available. Because the loaded weight reaches 2,502 pounds, the foundation under it does more work than the tank itself, so use the Tank Sizing Calculator and the Tank Sizing Guide to match capacity and footprint to your draw rate and available space. If you are building a private fire-protection reserve, our guide on fire-water reservoir tank design and NFPA 22 sizing walks through cold-climate and reserve-volume considerations. For grey-water, rainwater, and condensate setups, see our guide on industrial water reuse tank topology.
The mistake to avoid
The most common error on a tank this size is treating it as a drop-in swap for a different 300-gallon model without checking footprint and height. This is the 35 x 35 x 78 configuration, not the taller 35 x 89 or the wider 46 x 50 version, so verify you are comparing the same model by height, not just gallons. Compare this tank against the 35 x 89 buyer's guide and the 46 x 50 buyer's guide so the dimensions, fittings, and clearances line up with your install before you commit. Remember too that the 1.0 specific gravity rating is for water and water-like fluids only: do not use this tank for fertilizer, brine, or any chemical heavier than water on this rating.
