The Bushman 1000 Gallon Vertical Rainwater Harvesting Tank in dark brown holds a full 1,000 gallons of collected rainwater in a polyethylene shell that stands 65 inches tall on a 75-inch-diameter footprint. Note that geometry: it is wider than it is tall, a squat vertical tank with a large base circle and a low center of gravity rather than a narrow column. It is purpose-built for rainwater harvesting and outdoor water storage, with a dark brown wall that blends into a landscape. If you are sizing a vertical tank for a roof-catchment system, a 1000 gallon vertical tank like this one fits the gap between small garden barrels and the larger cistern range.
Will it work for your site?
Plan your pad and plumbing around the real numbers. Filled to capacity this tank carries roughly 8,340 pounds, and because it is rated to a specific gravity of 1.0 (water), the full-water load and the maximum rated contents weight are one and the same 8,340 pounds. That weight sits on a 75-inch-diameter circle, so set the tank on a level, fully supported base sized for the full footprint, not a narrow vertical-tank pad. Our concrete pad sizing guide walks through the ACI 360R-10 framework for getting that pad right. Because the specific gravity rating is 1.0, this tank is matched to water; it is not suitable for liquids denser than water such as acids, brines, or concentrated fertilizers, which require a higher-SG-rated tank.
Fittings and rainwater connections
This tank comes configured for a harvesting system rather than a bare drum. Per the technical drawing on this page, it carries an outlet and overflow kit rated for a 3-inch connection and a 1-inch polypropylene bulkhead fitting sealed with an EPDM gasket. EPDM is the right elastomer for rainwater service, so the as-shipped seal is matched to the contents. It also includes three flat-area fitting pads, a 10-inch by 12-inch flat, an 8-inch by 11-inch flat, and a 9-3/8-inch by 20-1/4-inch flat, which ship un-drilled as landing areas where you can add your own plumbing, gauges, or screened inlets. When you drill those pads, source matching EPDM gaskets to keep the whole tank chemically consistent. Reference the technical drawing on this page for exact fitting locations before you commit your inlet and overflow routing. For first-flush diverter sizing and inlet detailing, our guide to Bushman rainwater harvesting tanks and first-flush diverter sizing follows the Texas Manual on Rainwater Harvesting, 3rd Edition.
The mistake to avoid
The most common error on a tank this size is undersizing the catchment math, not the tank. Match the 1,000-gallon volume to your roof area and local rainfall before you buy, so the tank actually fills and the overflow does its job. Run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and if you are sizing across multiple sites or states, the guide to rainwater harvesting tank sizing by state covers regulations, rainfall, and real SKUs. If this tank will also serve as fire-water reserve on a rural property, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection.
