The Snyder Industries 1100 Gallon Vertical Water Storage Tank is a green, high-density linear polyethylene (HDLPE) vessel built for bulk water storage where you need real capacity in a compact footprint. It measures 53 inches tall on an 86-inch-diameter base, an unusually wide-and-low vertical storage tank profile, so confirm overhead clearance for the manway and gate or door width before delivery. Filled to capacity it carries 9,174 pounds of water across that 86.0 x 86.0 inch footprint, and that weight is the number that drives your whole install: it determines the pad you pour, the access route, and how you set the tank. The tank arrives empty and light enough to position with light equipment, then becomes a 9,174-pound fixed load once filled, so set it dry and fill it in place. For matching gallons to demand across a range of capacities, the Tank Sizing Calculator and Tank Sizing Guide walk you through the math.
Fittings and connections
This vertical water tank ships with the factory connections most water installs need, all detailed on the technical drawing on this page:
- Flanged outlet
- 12" x 15" fitting
- 1-1/2" polypropylene bulkhead fitting with EPDM gasket
- 2" polypropylene bulkhead fitting with EPDM gasket
- 18" polyethylene manway with 4" vent and tie-down
The vented manway matters: a sealed tank can deform under the vacuum of a fast draw-down or the pressure of a fast fill, and the 4 inch vent lets it breathe. The bulkhead ports pair polypropylene fittings with EPDM gaskets against a polyethylene tank wall that flexes under load. Snug those fittings to hand-spec, not by force; an overtorqued bulkhead is the single most frequent source of a slow weep on a poly tank, and honoring the EPDM gasket material is what keeps the seal. Check the technical drawing for fitting placement and port heights before you plumb.
Pad, footprint, and install planning
A green vertical water tank like this belongs on a level, fully supporting pad. With 9,174 pounds bearing on the 86.0 x 86.0 inch footprint when full, the pad has to carry the load evenly across the entire base, not just the perimeter. For getting the pad right, read Concrete Pad Sizing for Above-Ground Polyethylene Tanks, and once the tank is set, the Hydrostatic Test Methodology guide covers the water-fill acceptance test, pad-settlement monitoring, and fitting leak checks for a new install.
The mistake to avoid
This tank is rated at specific gravity 1.0, which is the exact rating for water and water-density liquids; at 9,174 pounds it reaches its maximum rated contents weight when filled with water. Do not press a 1.0-rated tank into denser chemical service, where the contents weigh more than water, without confirming the correct tank rating for that fluid first; call 866-418-1777 and we will help you match the right tank to your liquid. The second mistake is treating the green color as decorative. The opaque green wall limits light intrusion that promotes algae growth in stored water, which is a real reason to keep it green rather than swapping to a translucent tank. If your project leans toward fire reserve or reuse storage, the Fire-Water Reservoir Tank Design guide and the Industrial Water Reuse Tank Topology guide dig into design discipline for each.
