The Snyder Industries 4100 Gallon Vertical Water Storage Tank in black is a high-capacity, above-ground reservoir built for sites that need a single large water store. It holds 4,100 gallons in a 102-inch diameter footprint and stands 130 inches tall, molded from high-density linear polyethylene (HDLPE) and rated to a 1.0 specific gravity. Linear polyethylene is the standard resin for large water-only verticals, which is exactly what the 1.0 rating reflects: this tank is built for water and water-weight liquids, not heavier chemical service. The black shell blocks light to suppress algae on standing water, so it suits long-dwell storage like fire-water reserves, irrigation supply, and rainwater aggregation where water sits before it is drawn down.
Will it work for your site?
Two numbers decide that before anything else: clearance and weight. This tank needs roughly 11 feet of vertical clearance (130 in) and an 8.5 x 8.5 ft pad (102 x 102 in footprint), so check overhangs, sheds, and delivery access early. Filled, it carries a full-water weight of 34,194 lbs, and that load is the single most important figure here — the pad has to take all of it over the 102 x 102 inch footprint. Plan and pour the foundation around that number before the tank arrives. Our Concrete Pad Sizing guide walks through the ACI 360R-10 framework for sizing a slab under an above-ground polyethylene tank at this scale.
Sizing, reuse, and verification
If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match a vertical storage tank to your draw-down and refill cycle. For grey-water, rainwater, or HVAC-condensate aggregation, the Industrial Water Reuse Tank Topology guide covers how a tank this size fits a quality-banded storage train. For rural fire-protection reserves, the Fire-Water Reservoir Tank Design guide ties a tank this size into NFPA 22 sizing and freeze protection. Once the tank is set, run a controlled water fill rather than trusting a full tank on day one — our Hydrostatic Test Methodology guide covers staged fill discipline, pad settlement monitoring, and fitting leak checks so any movement shows up before the tank is at full load. Confirm fitting size and placement against the technical drawing on this page before you set the tank, since outlet positions drive your plumbing run.
The mistake to avoid
Under-building the foundation. A 34,000-pound load on an uneven or undersized pad leads to settlement, stress on outlet fittings, and eventually a leak. The black HDLPE shell handles the water and the UV exposure; the pad has to handle the weight. Size and pour the slab first, verify it, then deliver the tank.
This 4100 gallon vertical water storage tank ships LTL freight, quoted live to your ZIP. Snyder molds it at both a West Coast plant (Merced, California) and a Southeast plant (Albertville, Alabama), so freight is quoted from whichever is closer to your delivery address — a real cost advantage over a single-origin tank. Get a live rate with our Freight Cost Estimator, or call 866-418-1777 and we will quote freight to your ZIP and confirm offload requirements for a tank of this size.
