The Bushman 1320 Gallon Mocha Rainwater Collection Storage Tank is a polyethylene above-ground tank built for serious rainwater harvesting, stored-water reserves, and rural fire-protection supply. It holds 1,320 gallons in a mocha-toned exterior that blends into outdoor sites, and it stands 72 inches tall on an 82 x 82 inch footprint, making it wider than it is tall. That squat, wide profile gives it a low center of gravity, though it does call for a larger pad than a slim vertical tank of the same capacity. It is a dedicated water storage tank rated for a specific gravity of 1.0, meaning it is engineered for water and water-density liquids, not heavier chemical service.
Will it work for your site?
Plan your pad and your plumbing around real numbers before you buy. Filled to its full 1,320-gallon capacity, this tank carries roughly 11,009 pounds of water, and that 11,009 lb filled load on the 82 x 82 inch footprint is the figure that drives your pad design, not the shipping weight of the empty tank. The technical drawing on this page shows the outlet detail: this tank carries a single 1" NPT bulkhead fitting. A bulkhead is a gasketed connection, so verify and spec the bulkhead gasket and a matching 1" NPT supply line before install, and plan separately for your inlet, overflow, and any first-flush return lines, since the one bulkhead is the only factory connection. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the capacity and dimensions match your collection demand and the space you have.
The mistake to avoid
The most common error with a tank like this is loading it past what the resin is rated for. At a specific gravity rating of 1.0, this tank is meant for rainwater and other water-density liquids. Do not press it into service for denser solutions or chemical storage that would exceed a 1.0 specific gravity; honoring the rating is what keeps the wall integrity intact over the tank's service life. For a footprint and filled load this size, also confirm a level, properly engineered base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the pad carries the full 11,009 lb filled weight without settling or point-loading the base.
Putting the captured water to work
This size is a workhorse for whole-property harvesting. If you are designing a collection system, our guide to Bushman rainwater harvesting tanks and first-flush diverter sizing follows the Texas Manual on Rainwater Harvesting, 3rd Edition, for keeping debris and contaminants out of stored water. Properties combining rainwater, grey-water, and condensate into one storage train can review our industrial water reuse tank topology guide. For rural and remote sites holding water in reserve for private fire protection, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service.
