The Snyder Industries 7000 Gallon ASTM Black Heavy Duty Vertical Storage Tank (SKU 5300700N51) is a full-size bulk vertical storage tank molded in High Density Linear Polyethylene and rated to a 1.9 specific gravity. That 1.9 rating is the whole point of the "Heavy Duty" designation: the wall is built to hold contents far denser than water, so this SKU already covers dense process liquids and brines up to 1.9 SG. You are buying the heavy-duty rating, not upgrading to it — there is no separate tank to step up to. At 7,000 gallons of plain water (about 58,380 lb of liquid) you run well inside the structural envelope, with headroom up to a rated contents weight near 110,922 lb.
Will this tank work for your site?
The footprint is 142 x 142 inches — an 11.83-foot square base — with a 122-inch (10.17 ft) standing height. Plan overhead clearance above 10 feet, because the 18" PE threaded and vented fitting and the manway riser stack add height above that 122 inches. The black exterior blocks light penetration, which discourages algae growth and makes this a practical choice for outdoor bulk water, process water, and reserve storage. If you are still confirming that 7,000 gallons matches your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you pour a pad.
Pad loading and fittings
A filled tank puts real load on the base: 58,380 lb of water over the 142 x 142 in (139.9 sq ft) footprint is roughly 417 lb per square foot, and at the 1.9 SG maximum (110,922 lb) it is about 793 lb per square foot. Size the concrete for the load you will actually run — our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. The tank is configured with a flange, a 12" x 28" fitting/S.U.M.O., an 18" PE threaded and vented fitting, a second fitting/S.U.M.O., and a manway with 15" access for inspection and cleaning. Confirm the flange bolt pattern and both S.U.M.O. locations against the technical drawing on this page before you rough in plumbing, and verify your gasket and bulkhead-fitting material (EPDM vs. Viton) against the liquid you are storing — a 122-inch-tall tank leaves no room to relocate connections after the pad is set. If this reservoir is headed into a rural fire-water role, our guide on fire-water reservoir tank design covers NFPA 22 sizing and cold-climate freeze protection.
