The Bushman 5000 Gallon Vertical Rainwater Harvesting Tank in dark brown is a 5,000-gallon polyethylene tank built for above-ground rainwater storage. It stands 161 inches tall on a 102 x 102 inch footprint, so plan the slab and overhead clearance before delivery. The dark brown color suits residential and rural sites where a low-visibility tank blends into the landscape rather than standing out. For homeowners and contractors sizing a rainwater system, this is the large end of a single-tank install before you step up to multi-tank batteries.
Will this tank work for your site?
This is a water tank, rated at a specific gravity of 1.0 - it is engineered to hold rainwater and other contents up to the weight of water, not heavier liquids. Filled to capacity, the tank and its contents carry roughly 41,700 pounds, and that figure is the filled, in-service load that drives your pad design and soil-bearing decision - it is not the shipping weight. At a 102 x 102 inch footprint that load has to be supported on a flat, level surface across the full base. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm this 5,000-gallon size against your roof catchment area and rainfall, and read our guide on concrete pad sizing for above-ground polyethylene tanks for the ACI 360R-10 framework behind a 41,700-pound load.
Fittings and what is on the tank
Per the technical drawing on this page, the tank is configured with three flat fitting areas (15" x 15", 12" x 15", and 13" x 25") plus an outlet and overflow kit (4 inch) and a 1 inch bulkhead fitting in polypropylene with an EPDM gasket. The flat fitting pads let you place inlets, outlets, and overflow connections where your plumbing needs them. Confirm EPDM is compatible with your collected water and any additives before plumbing the 1-inch bulkhead. Note the access reality on a tank this tall: the top fittings sit at roughly 13.4 feet, so plan ladder or platform access for the inlet, screen, and overflow maintenance. The included 4 inch outlet/overflow kit and the overflow path matter on a rainwater harvesting tank - in a hard rain the tank will fill and overflow, so the overflow has to be plumbed away from the foundation. Our guide on Bushman rainwater harvesting tanks and first-flush diverter sizing walks through pre-tank filtration sizing per the Texas Manual on Rainwater Harvesting, and the rainwater harvesting tank sizing by state guide covers the regulations and rainfall numbers behind picking a 5,000-gallon vertical tank.
The mistake to avoid
The most common error on a tank this size is treating the pad as an afterthought. A full 5,000-gallon tank is a 41,700-pound point of load on your site, and an under-built or out-of-level base is what cracks tanks and stresses fittings over time. Size the slab for the rated contents weight first, then set the tank. If you are sizing this tank for fire-protection storage in a rural or remote location, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze-protection considerations for a polyethylene tank in that role.
The empty tank ships dry by LTL freight from the Bushman plant in Fairfield, Texas, with freight quoted live to your ZIP code - the 41,700 lb figure is the filled in-service load, not the crated shipping weight.
