The Bushman 5000 Gallon Mocha Rainwater Collection Tank is a polyethylene vertical built for serious above-ground rainwater harvesting, holding 5,000 gallons in a 102-inch diameter, 161-inch tall body. The mocha color blends into residential and rural settings while shielding stored water from sunlight to discourage algae growth. If you are sizing a cistern for whole-property catchment, fire reserve, or supplemental irrigation, this is the large-format Bushman size that anchors the system.

Will it work for your site?
The footprint is 102 x 102 inches, so you are planning for a square pad roughly 8.5 feet on each side. Filled to capacity, the tank and its water reach 41,700 pounds, which is also the maximum rated contents weight, so the pad has to be engineered for that load, not the empty tank weight. Our concrete pad sizing guide walks through the ACI 360R-10 framework for getting that foundation right before delivery. The tank carries a 1.0 specific gravity rating, which is exactly matched to water, so it is sized for rainwater and other water-weight service; for chemical or heavier-than-water contents, a higher-SG-rated tank is required rather than this water configuration.
Fittings and connections
Per the technical drawing on this page, this tank is configured with an outlet and overflow kit rated at 4 inches and a 1-inch bulkhead fitting with a polypropylene body and EPDM gasket. Before you order plumbing, verify that your supply-side pipe and gasket material match that 1-inch PP/EPDM connection; EPDM is appropriate for ambient rainwater service. The drawing also shows three flat fitting areas sized at 15" x 15", 12" x 15", and 13" x 25" — these are flat, un-ported pads that serve as field-drillable mounting locations for adding inlets, vents, level gauges, or additional bulkheads sized to your system. Review the technical drawing on this page to confirm exact port placement and pad locations against your inlet, overflow, and draw lines before you set the tank. If you are still mapping total storage volume against your roof catchment area, run the numbers through our Tank Sizing Calculator and the companion Tank Sizing Guide.
The mistake to avoid
The most common rainwater harvesting error at this scale is skipping first-flush diversion, which lets the dirtiest initial runoff carry roof debris and contaminants straight into 5,000 gallons of storage. Our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting shows how to size that diverter correctly for a tank this large. If this reserve also doubles as private fire-water storage, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
