The Bushman 150 Gallon Plastic Vertical Rainwater Harvesting Tank (BM-30119) is a black polyethylene tank built for above-ground rainwater harvesting, standing 58 inches tall on a compact 30 x 30-inch footprint. The black color blocks sunlight to suppress algae growth in stored rainwater, and the slim vertical profile fits alongside a house wall, on a porch corner, or anywhere a 30-inch-square pad will sit. If you searched for a Bushman 150 gallon black vertical tank for rainwater, this is the tank, and the sections below cover how it works, what it weighs full, and how it ships.
Specifications and fittings
This is a 150-gallon vertical rainwater tank molded from polyethylene with a specific gravity rating of 1.0, meaning it is rated for water and water-density liquids. Dimensions are 58 inches high by 30 inches in diameter, on a 30.0 x 30.0-inch footprint. Because the barrel is round at 30 inches but the pad you size is the 30 x 30-inch bounding box, plan the slab to the square, not the drum. Per the technical drawing on this page, the tank carries two flat fittings (8" x 7" and 8" x 6") that serve as landing pads for the inlet and downspout connection, a 3-inch outlet and overflow kit that handles drawdown and overflow, and a 3/4-inch bulkhead fitting for a spigot or hose tap. That bulkhead uses a polypropylene body with an EPDM gasket; EPDM is the right sealing elastomer for water and rainwater service, so the seal material is matched to the fluid. See the technical drawing on this page for fitting locations before you plumb a downspout or first-flush diverter into it.
Sizing, weight, and pad
Filled to capacity, this tank holds roughly 1,251 pounds of water, which is also its maximum rated contents weight. That load sits on a 30 x 30-inch base, so the pad beneath it has to carry the full weight without settling or tilting. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 150 gallons matches your roof catchment and rainfall, and read Concrete Pad Sizing for Above-Ground Polyethylene Tanks to size and level the slab. For catchment math and first-flush diverter sizing, the Bushman first-flush diverter sizing guide and Rainwater Harvesting Tank Sizing by State walk through the regulations and rainfall numbers that drive tank volume. If you are sizing this tank as a rural fire-water reserve or a freeze-protected reservoir, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate protection.
The mistake to avoid
The most common error on a tank this size is treating the empty 30-inch footprint as the whole story and skipping the pad. Empty, this tank is easy to move; full, it is over 1,200 pounds concentrated on a square yard of ground. Set it on bare soil, gravel, or an unlevel surface and it can lean, stress the fittings, and split a connection. Build a flat, load-rated pad first. Also confirm the 3/4-inch bulkhead and 3-inch overflow are plumbed so overflow discharges away from the foundation, not back toward it.
BM-30119 ships LTL freight from the Bushman plant in Fairfield, Texas, with the rate quoted live to your ZIP code. The 1,251-pound full-water weight is your in-service load, not a shipping figure; the tank travels empty, so freight is driven by its dimensions, not its filled weight.
