The Snyder Industries 210 Gallon Black Heavy Duty Vertical Storage Tank is a 55-inch-tall vertical tank built on a 36 by 36-inch square footprint, molded in black polyethylene and rated to a 1.9 specific gravity. That 1.9 rating is the headline number here: it is the heavy-duty version of this class, built to hold denser contents at full volume with margin in the wall. If you are storing water or another dense liquid and want that margin, this Snyder vertical tank is the top-tier rating in the size.
Will it work for your site?
The tank holds 210 gallons. Filled with plain water, the contents weigh about 1,751 pounds, and at the full 1.9 SG rating the tank is built to carry up to 3,328 pounds of contents. Use those two numbers to plan your pad: the 1,751-pound figure is the real load for water service, and the 3,328-pound figure is the structural ceiling for the densest liquid the wall is rated for. Spread that ceiling across 210 gallons and it works out to roughly 15.8 pounds per gallon, which is the ~1.9 SG gate — match your liquid's specific gravity to 1.9 or below and you are inside the rating. The 36 by 36-inch footprint keeps the base compact, but at 55 inches tall the filled tank carries its weight high, so a level, full-bearing pad is not optional. Run your contents and dimensions through the Tank Sizing Calculator if you are choosing between capacities, and the Tank Sizing Guide walks through how footprint and height interact with siting.
Fittings and pad
Fitting configuration for this SKU is not specified in our data, so confirm outlet size and placement before you order by calling 866-418-1777. On the pad itself, a black vertical tank on a square footprint wants continuous, level support under the entire base. Before you pour or place, read the Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide, which covers the ACI 360R-10 framework for slab support under a polyethylene tank. The black wall is a working feature for stored water: black polyethylene blocks light transmission, suppressing the algae growth that a translucent tank can allow. If this tank is part of a stored-water reserve for rural fire protection, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and freeze protection for cold-climate service.
The mistake to avoid
Do not assume the 1.9 SG rating means you can skip a real pad or under-size your foundation. The higher SG rating raises the structural ceiling inside the wall; it does not change physics under the tank. At up to 3,328 pounds of contents sitting 55 inches off the ground on a 36-inch base, an uneven or partial-bearing surface concentrates load and is the most common avoidable failure on a heavy-duty vertical. For dense liquids, give thermal expansion its room too: the Snyder Captor freeboard guide lays out the freeboard and expansion methodology per ASTM D1998 that keeps you from filling to a number you cannot actually use. Set the tank level, set it on full bearing, and the 1.9 rating works for you instead of against you. For water-reuse setups aggregating grey-water, rainwater, or HVAC condensate, the Industrial Water Reuse Tank Topology guide covers banded-quality storage trains.
