The Bushman 2500 Gallon Mocha Rainwater Collection Tank is a 2,500-gallon polyethylene tank built for harvested rainwater storage at homes, ranches, and remote sites. It stands 95 inches tall on a 96 x 96 inch footprint, so plan your pad and overhead clearance around that roughly 8-foot height and square base. The Mocha color blends into most landscapes, and the tank carries a 1.0 specific gravity rating that matches the weight of water. It ships from Fairfield, Texas, so a buyer can eyeball LTL distance to their ZIP before pricing anything.
Will this tank work for your rainwater system?
At full capacity this tank holds 2,500 gallons of water weighing 20,850 pounds, which is also its maximum rated contents weight. That load tells you what the pad underneath has to carry: a 96 x 96 inch footprint supporting more than ten tons when full demands a level, properly engineered base. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. If you are still settling on capacity for your roof area and rainfall, the Tank Sizing Calculator and Tank Sizing Guide help you size against demand.
Fittings and plumbing
The technical drawing on this page shows the molded fitting locations for this tank. There are three distinct flat fitting zones you can drill for bulkhead fittings and connections: a 12" x 14" area, an 8" x 14" area, and a larger 12" x 24" area sized for a manway or a large bulkhead, while the smaller zones suit inlet and draw-off plumbing. The tank comes set up with a 4-inch outlet and overflow kit included (not an upsell) and a 1-inch bulkhead fitting with a polypropylene body and an EPDM gasket. That seal pairing is the right one for water service: EPDM is the correct elastomer for rainwater and weathers UV and ozone well, and the polypropylene body will not corrode like metal. Route and screen the overflow to daylight so it can shed surplus flow cleanly. For first-flush diversion and inlet detail specific to Bushman rainwater tanks, see our first-flush diverter sizing guide based on the Texas Manual on Rainwater Harvesting, 3rd Edition.
The mistake to avoid
The most common error with a tank this size is underbuilding the foundation. Twenty-thousand-plus pounds of water concentrated on a 96 x 96 inch square will crack an undersized or unlevel slab and stress the tank shell, so settle the pad before the tank, not after. One spec point to respect: this tank is rated to 1.0 specific gravity, so its rated contents weight equals the weight of water and there is no headroom for denser liquids. It is a water-only tank and is not suitable for chemicals heavier than water. If this tank feeds a private fire-protection reserve or a larger reuse system, our guides on fire-water reservoir design and industrial water reuse topology cover how this tank fits into a multi-tank rain, grey-water, and condensate train.
