The Bushman 4050 Gallon Black Rainwater Collection Storage Tank is a vertical polyethylene tank built for serious above-ground rainwater harvesting, fire-water reserve, and bulk non-potable water storage. It holds 4,050 gallons in a 129-inch-tall body on a tight 101 x 101-inch footprint, and the opaque black polyethylene blocks light to help discourage algae growth in stored water. If you are searching for a large black water storage tank or a Bushman rainwater tank that can anchor a whole-site collection system, this is the size that does it. Quick dimensions for clearance and gate planning: 129" tall, 101" diameter, 101 x 101-inch footprint.
Will it work for your site?
This tank is rated to a specific gravity of 1.0, which matches water exactly, so it is sized for water and water-density liquids, not heavier chemicals. Plan your pad and supports around the loaded weight: filled to capacity it carries roughly 33,777 pounds of water on its 101 x 101-inch base. That is a substantial concentrated load, so the foundation matters as much as the tank. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks so the base under all 33,777 pounds is engineered correctly. Per the technical drawing on this page, the tank is configured with one 1" NPT bulkhead fitting; inlet, overflow, and draw-off plumbing is field-added, so confirm that single bulkhead against the drawing before you lay out your connections.
Sizing it into your system
At 4,050 gallons this tank is large enough to serve as the primary reservoir in a rainwater harvesting train or a rural fire-water supply. If you are designing a collection system, the first-flush diverter sizing guide (built on the Texas Manual on Rainwater Harvesting, 3rd Edition) helps you keep the first dirty runoff out of the tank. For private fire protection, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. Running grey water, HVAC condensate, or rainwater into a reuse train? The industrial water reuse topology guide maps out quality-banded storage trains. To check this 4,050-gallon size against your demand and rainfall, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.
The mistake to avoid
The most common error on a tank this large is undersizing the foundation. A tank rated to 1.0 specific gravity is correct for water, but the loaded weight of nearly 33,777 pounds demands a level, fully supported, engineered pad. Setting a tank this size on uneven ground, gravel, or a pad that does not support the full footprint can crack the base. Confirm the single 1" NPT bulkhead against the technical drawing before installation, and do not exceed the 1.0 specific gravity rating with denser liquids.
