The Snyder Industries 330 Gallon Black Vertical Water Storage Tank (SKU WB24R) is a polyethylene vertical water tank built for above-ground bulk storage where you need a compact footprint and a clean fitting layout. At 50 inches tall on a 47 by 47 inch footprint, it holds 330 gallons and ships rated to a specific gravity of 1.0, meaning it is sized for plain water and other contents no heavier than water. The black color limits light penetration to slow algae growth in outdoor service. One note before you order: this tank ships from a single West Coast plant in Merced, CA, so if you are East or Midwest, price the LTL freight to your ZIP early in your decision.
Will it work for your install?
Start with the weight, because it drives the pad and the plumbing. Filled to capacity with water, this vertical storage tank carries 2,752 pounds of contents, and its maximum rated contents weight is the same 2,752 pounds at the 1.0 specific-gravity rating. That number sizes your pad and sets your standoff. The 47 by 47 inch footprint and 50 inch height clear standard gates and sit on a modest pad without a tall stand. For fittings, the tank is configured with a bulkhead flange, a 1-1/2 inch polypropylene Eco-bulkhead fitting with an EPDM gasket and textured face, a 2 inch standard polypropylene bulkhead fitting with EPDM gasket, and an 18 inch polyethylene manway with an integral 4 inch vent and tie-down. The manway is your inspection and cleanout access, and because the 4 inch vent is built into it, the closed tank breathes during drawdown without separate vent plumbing, which prevents vacuum collapse.
Plan your plumbing and pad
Both bulkhead fittings have polypropylene bodies and EPDM gaskets, so confirm your pipe, thread, and any wetted hardware mate to PP and EPDM before you plumb. Plan the 2 inch bulkhead as your larger draw or fill port and the 1-1/2 inch as the secondary connection, then check the exact port elevations and the inlet, outlet, and vent positions against the technical drawing on this page so your manifold lines up. If you are still choosing a size, run your draw-down and refill cycle through the Tank Sizing Calculator and review the Tank Sizing Guide so the 330 gallon capacity fits your duty. Because a full tank puts roughly 2,752 pounds onto a small footprint, the pad must be level, continuous, and properly sized; our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. Once the tank is set and plumbed, follow the hydrostatic test methodology to verify fitting seals and watch for pad settlement before full service.
The mistake to avoid
The SG rating is the trap. This is a 1.0 specific-gravity tank, engineered for water-weight contents. Do not put anything denser than water in it and expect the same service life; heavier contents need a higher-SG-rated tank, not this one. If your contents are heavier than water, call 866-418-1777 and we will spec a higher-SG tank for that load. For rural fire-protection storage or water-reuse trains where this size fits well, see our guides on fire-water reservoir design and industrial water reuse tank topology.
