The Bushman 3000 Gallon Dark Brown Rainwater Collection Storage Tank is a polyethylene above-ground tank built for serious rainwater harvesting, with a 3,000-gallon working capacity and an opaque dark brown finish that blocks light to slow algae growth in the stored water and blends into landscaping. It stands 113 inches tall, and its round body fits within a 96-inch by 96-inch envelope, so plan on a full 8-foot by 8-foot pad and confirm the vertical clearance for delivery and the inlet plumbing up top before you commit a slab location.
Will this water storage tank work for your site?
This is a dedicated rainwater tank rated for water service at a specific gravity of 1.0, meaning it is engineered for the weight of water, not for heavier chemical liquids. Filled to capacity, the contents weigh roughly 25,020 pounds, and that full-water load is the single number that should drive your foundation decision. A tank this size belongs on an engineered, level pad sized for the full load rather than on bare or compacted soil that can settle unevenly. Keep in mind this is an above-ground poly tank with no integrated freeze protection; in cold climates plan your insulation or heat-trace strategy accordingly, and walk through our cold-climate fire-water reservoir design guide for freeze-protection engineering. Before you pour, review our concrete pad sizing guide for above-ground polyethylene tanks, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 3,000 gallons matches your roof catchment and demand.
Sizing it into a rainwater harvesting system
Three thousand gallons is a substantial reserve for residential and light-commercial rainwater collection, irrigation banking, and supplemental water storage. The right capacity depends on your roof area, local rainfall, and how steadily you draw the tank down between rains. For Texas systems specifically, our guide to first-flush diverter sizing per the Texas Manual on Rainwater Harvesting walks through keeping the dirty first flush out of stored water. If you are aggregating multiple water sources, the industrial water reuse tank topology guide covers quality-banded storage trains. Refer to the technical drawing on this page for inlet, outlet, and overflow port locations and sizes as you lay out your plumbing.
The mistake to avoid
The most common error with a tank this size is under-building the foundation. At about 25,020 pounds full, this is not a tank you set on a couple of patio pavers; an inadequate or unlevel base can stress the tank wall and shorten its life. Size the pad for the full water weight, get it dead level, and your tank will serve for years. The second mistake is treating a water tank like a chemical tank. This Bushman is rated at a specific gravity of 1.0 for water, so do not store liquids heavier than water in it.
