The Bushman 125 Gallon Vertical Rainwater Harvesting Tank in dark brown is a polyethylene catchment tank built for above-ground rain capture on homes, cabins, RV setups, and small acreage. It stands 50 inches tall on a 30-inch diameter footprint, so it tucks against a wall or under a downspout without claiming much ground. Filled to capacity it holds 125 gallons and carries roughly 1,042 pounds of contents on that 30-inch circle - a number that drives the pad you put under it more than anything else.
Will it work for your site?
This is a water tank rated to a specific gravity of 1.0, meaning it is engineered for water and rainwater service, not heavier liquids. The fitting layout shown on the technical drawing for this tank includes two flat molded fitting pads (an 8" x 7" and an 8" x 6") that give you clean, flat landing zones to drill and mount your inlet and a second penetration without cutting into the curved sidewall. It also carries a 3-inch outlet-and-overflow kit and a 3/4-inch bulkhead fitting with a polypropylene body and an EPDM gasket - the correct elastomer for rainwater service, so the outlet seals without aftermarket parts. Between them you get the standard arrangement that lets you plumb a downspout in, an overflow out, and a hose bib or pump line off the bottom. See the technical drawing on this page for exact fitting positions before you set the tank and commit your plumbing penetrations. To match catchment area and rainfall to the right capacity, the Tank Sizing Calculator and Tank Sizing Guide walk you through the math.
Sizing it into a real harvesting system
A 125-gallon vertical tank is a starter or supplemental size in most rainwater builds - good as an RV water tank, a hose-bib reservoir, or one of several linked tanks. Size your first-flush diverter to the tank and the roof feeding it; our guide on Bushman rainwater harvesting and first-flush diverter sizing works the numbers against the Texas Manual on Rainwater Harvesting, and rainwater tank sizing by state covers regulations and rainfall by region. On rural and remote sites, a linked bank of these tanks can also serve as a private fire-water reserve - our guide on fire-water reservoir tank design to NFPA 22 covers the sizing discipline.
Don't skip the pad
The mistake to avoid on this tank is setting it on bare or uneven ground. At full water weight, all 1,042 pounds bear on a 30-inch diameter base, so the tank needs a level, fully supporting pad - a uniformly supported tank distributes that load evenly across its base instead of concentrating it on high spots. Our walkthrough on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework for getting that base right.
