The Bushman 1500 Gallon Mocha Rainwater Collection Tank is a 1,500-gallon polyethylene tank built for above-ground rainwater harvesting, holding rain captured from roof catchment for irrigation, livestock, garden, and household supplemental supply. It stands 63 inches tall on a 94 x 94 inch footprint, so it tucks into a corner or along a wall without sprawling across a yard, though you will want headroom above the shell for the inlet plumbing and lid access. The mocha color is muted to blend into residential and rural settings and to keep sunlight out of the water, which slows algae growth in stored rain.
Will it work for your site?
This is a water-service tank rated to a specific gravity of 1.0, which is exactly what stored rainwater needs. The polyethylene shell carries water and water-density liquids without issue. Plan your pad and your plumbing around a full tank: at capacity it holds about 12,510 pounds of water, and that full water weight is also the maximum rated contents weight. That load sits on the 94 x 94 inch footprint roughly 63 inches to the top of the shell, so the ground underneath has to be flat, fully supporting, and engineered for the weight, with extra clearance above for fill plumbing if you are fitting it under an eave or in a covered area. If you are sizing a pour, walk through the concrete pad sizing framework before you set the tank. To confirm this 1500-gallon Bushman is the right capacity for your roof area and rainfall, run the numbers in the Tank Sizing Calculator and read the Tank Sizing Guide. For fitting locations and overall dimensions, see the technical drawing on this page, and confirm the exact inlet, outlet, and overflow positions there or by phone before you order bulkhead or valve hardware.
Getting the most from a rainwater system
A collection tank is one piece of a harvesting setup. First-flush diversion keeps the dirtiest initial roof runoff out of your stored water, and Texas has published clear guidance on sizing it; our writeup on Bushman rainwater harvesting and first-flush diverter sizing walks through it per the Texas Manual on Rainwater Harvesting. If your goal is rural fire protection or a remote-site reservoir, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. And if you are aggregating grey-water, rainwater, or HVAC condensate, the water reuse tank topology guide lays out quality-banded storage trains.
The mistake to avoid
The most common error with a tank this size is under-building the base. Rainwater is heavy, and at roughly 12,510 pounds full, an uneven, soft, or undersized pad will let the tank settle, lean, or stress the wall at the outlet. Set it level on a fully supporting foundation sized for the load before you fill it, and plumb the overflow outlet to carry excess water away from the base so it never scours or undermines the pad. The second mistake is skipping pre-tank filtration: install a leaf screen and first-flush diverter so debris and the dirtiest runoff never reach the stored rain.
