The Snyder Industries 1100 Gallon Vertical Water Storage Tank in black is a polyethylene vertical tank built for above-ground bulk water storage. It stands 53 inches tall on an 86 x 86 inch footprint and holds 1,100 gallons. Snyder rates it to a specific gravity of 1.0, meaning it is engineered for water and water-weight contents — full, it carries 9,174 pounds, the maximum rated contents weight for this model. If you are comparing vertical storage tanks for a water storage project, those three numbers — capacity, footprint, and full weight — drive the pad, the plumbing, and the freight.
What you get and how it is fitted
This vertical water tank ships with an 18-inch polyethylene manway assembly that includes a 4-inch vent and tie-down (the "ASM MANWAY 18IN PE W/4IN VENT W/TIE SII" on the build sheet). The outlet and bulkhead fittings come factory-installed with EPDM gaskets — EPDM is the correct wetted elastomer for water and ambient service, so the seal material is specified, not a guess. You get a 2-inch polypropylene EPDM bulkhead as your gravity-feed or draw outlet, a 1-1/2 inch polypropylene EPDM bulkhead for a secondary line such as overflow, recirculation, or fill return, plus a flange and a 12 x 15 inch fitting that give you future tie-in points without drilling the wall. The vent on the manway matters — a vertical water tank needs to breathe as you fill and draw down, and that is handled here. See the technical drawing on this page for exact fitting locations and elevations before you set your inlet and outlet plumbing.
Sizing the pad and the service envelope
At 9,174 pounds full, this tank puts real load on whatever it sits on. An above-ground polyethylene tank this size wants a level, continuous, load-rated pad — our concrete pad sizing guide walks the ACI 360R-10 framework, and the 86 x 86 inch footprint is the dimension to build to. Remember the vertical service envelope too: the 18-inch top manway and vent sit on a 53-inch-tall tank, so leave overhead clearance above that height to open and service them if you are building a shed or enclosure. To confirm 1,100 gallons matches your draw and refill cycle, run the numbers in our Tank Sizing Calculator or read the Tank Sizing Guide. After install, a water-fill acceptance check is the cheapest insurance you will buy — our hydrostatic test methodology covers fill discipline, pad-settlement monitoring, and fitting leak detection on those EPDM-gasketed bulkheads. For rural fire-water reservoirs or industrial water-reuse trains, this tank's volume slots cleanly into a banded storage stack.
The mistake to avoid
This is a 1.0 specific gravity tank. That rating is the line: it is built for water and water-weight liquids. Do not put a heavier-than-water fluid in it expecting the same service life — a denser load puts the wall under stress it was not rated for. If your contents are anything other than water at ambient density, confirm their specific gravity against the tank rating first, and if they exceed 1.0 SG, call 866-418-1777 and we will spec the correct higher-rated tank. Black is the right color for outdoor service — UV-stable and it won't grow algae the way translucent tanks can — and for cold-climate installs, the freeze-protection section of our fire-water reservoir guide covers keeping stored water liquid through the season.
