The Snyder Industries 550 Gallon Vertical Water Storage Tank in black is a high density linear polyethylene tank built for above-ground bulk water storage. It stands 77 inches tall on a 48-inch round footprint, holds 550 gallons, and carries a 1.0 specific gravity rating - meaning it is engineered for water and water-density liquids. The black pigment is opaque and blocks light from passing into the stored water, which helps keep the contents clean. This is the tank to spec when you need a tall, small-diameter vertical that fits a tight pad while still banking a meaningful water storage reserve.
Will it work for your site?
Filled to capacity with water, this vertical storage tank carries 4,587 pounds of contents, and 4,587 pounds is the maximum rated contents weight - so size your concrete pad and any structural support around that figure at full water. The 48.0 x 48.0 inch footprint is what your pad or compacted base has to carry, and the 77-inch height makes this a vertical tank rather than a sprawling low-profile unit. Because it is rated to 1.0 specific gravity, keep it on water and water-weight liquids. If your liquid runs heavier than water - fertilizer, brine, many chemicals - this 1.0 SG tank is the wrong spec; use the Tank Sizing Guide to step up to a higher-SG vertical, or run the Tank Sizing Calculator to match gallons and footprint to your demand.
Fittings and access
The drawing for this tank shows a plumb-ready port package: a 2 inch standard polypropylene bulkhead fitting and a 1-1/2 inch polypropylene Eco bulkhead fitting, both sealed with EPDM gaskets, plus a flange. That gives you two usable bulkhead outlets for inlet, outlet, or overflow before you add anything. The polypropylene fitting bodies and EPDM seals are the correct pairing for water and water service, matching the 1.0 SG water rating. Up top, access is through an 18 inch polyethylene manway that arrives with a 4 inch vent and tie - that integrated vent is what lets the tank breathe during fast fill and drawdown, so the access package is sized to avoid the under-venting failures that hit tall verticals during rapid draw. For exact port locations, elevations, and the manway position, see the technical drawing on this page before you plumb the inlet and outlet.
Installation discipline
A vertical this tall earns its reliability from the base it sits on. Size and pour the pad correctly using Concrete Pad Sizing for Above-Ground Polyethylene Tanks, then prove the install with a controlled water fill per the Hydrostatic Test Methodology guide to monitor pad settlement and catch any fitting leak before the tank goes into service. If this reserve feeds rural fire protection or a reuse train, the fire-water reservoir design guide and water reuse topology guide cover the engineering around the tank.
This 550 gallon black vertical ships LTL freight from the Snyder plant in Merced, California, with freight quoted live to your ZIP. Shipping from California on a heavy LTL item, you will want the number before you commit - pull your live quote from the Freight Cost Estimator or call us at 866-418-1777. The one mistake to avoid: do not over-fill past the rated water weight or put a heavier-than-water liquid in a 1.0 SG tank. Listed before freight, this is a workhorse vertical water storage tank for anyone banking a clean reserve.
