The Bushman 3000 Gallon Rainwater Collection Tank in Mocha is a 3,000-gallon polyethylene water storage tank built for rainwater harvesting and bulk water storage. It stands 97.5 inches tall on a 102-inch by 102-inch footprint, so you can confirm it fits your pad and any overhead clearance before it arrives. The opaque Mocha color limits light transmission into the tank to help discourage algae growth and blends into a yard or building exterior better than a bright white tank. This is a water storage tank rated to a 1.0 specific gravity, meaning it is engineered for fresh water and rainwater - not heavier liquids.
Will this tank work for your site?
At full capacity this tank holds roughly 25,020 pounds of water. That single number drives almost every install decision: the ground or pad under it has to carry better than 12 tons when the tank is full. Spread across the 102-inch by 102-inch footprint, that works out to roughly 2.4 pounds per square inch, or about 344 pounds per square foot distributed - the bearing pressure your concrete contractor actually designs to. A properly sized, level pad keeps the tank from settling or stressing the wall. Our concrete pad sizing guide lays out the ACI 360R-10 framework for getting that base right. If you are weighing this 3,000-gallon size against a smaller or larger model, run your roof catchment and demand numbers through our Tank Sizing Calculator and the Tank Sizing Guide so you buy the capacity your site actually needs. The technical drawing on this page shows the tank's profile and dimensions for layout planning.
Built for rainwater harvesting and water storage
The 1.0 specific gravity rating tells you exactly what this tank is for: fresh water and collected rainwater. Paired with a first-flush diverter and proper inlet screening, it forms the storage core of a rainwater harvesting system. Our guide on Bushman rainwater harvesting tanks and first-flush diverter sizing walks through the catchment math. For cold-climate or winter standby service, review the freeze-protection engineering covered in our fire-water reservoir design notes, and if you are aggregating rainwater with grey-water or condensate, see our industrial water reuse topology breakdown.
The mistake to avoid: the pad and the weight
The most common error on a tank this size is setting it on an undersized or unlevel base. A full 3,000-gallon tank puts more than 25,000 pounds onto its 102-inch by 102-inch footprint, and an unprepared base will let it settle, tilt, or stress the lower wall. Get your concrete or compacted base squared away before delivery. Just as important: keep this 1.0-rated tank in fresh-water and rainwater service. It is not built for heavier chemical contents, and putting a liquid denser than water in a tank rated to a 1.0 specific gravity overstresses the wall it was never designed to hold.
This tank ships LTL freight from the Temecula, California plant, quoted live to your ZIP code. Because it originates on the West Coast, California, Arizona, Nevada, and Pacific Northwest buyers get the shortest freight lane from here, while East Coast destinations should expect a longer haul on a 25,000-pound tank.
