The Bushman 5050 Gallon Black Rainwater Collection Storage Tank is a 5,050-gallon polyethylene water storage tank built for serious rainwater harvesting and bulk water storage. It is a wide, low-profile vessel: 96 inches tall on a 129 x 129 inch footprint, meaning it is wider than it is tall, so the footprint - not the height - drives your siting. Plan the pad before it arrives. It answers the three questions every buyer has: will it hold what I need, how does it ship, and what do I have to get right.
Will it work for your site
Capacity is 5,050 gallons. The specific gravity rating is 1.0, which is exactly right for water (water has a specific gravity of 1.0) and the correct rating for rainwater, fresh water, and general non-chemical storage. Filled with water this tank carries roughly 42,117 pounds of contents, and its maximum rated contents weight is the same 42,117 pounds. That number drives everything underneath it. The 1.0 rating means this tank is engineered for water and similar 1.0-density liquids only; denser or chemical service requires a tank rated above 1.0, so do not press this one past water. For sizing your harvest against roof area, rainfall, and demand, run the Tank Sizing Calculator and read the Tank Sizing Guide before you commit to a single 5,050-gallon vessel versus a multi-tank train.
Fittings and the technical drawing
This tank uses bulkhead-type fittings. For exact fitting locations, sizes, and the full dimensional layout, see the technical drawing on this page rather than working from the headline numbers alone. Because bulkhead fittings are gasket-sealed, the real install-failure point is the gasket and seal: verify the gasket seats correctly against your connecting pipe material and match the bulkhead size to your first-flush, outlet, and overflow plumbing before installation. If you are harvesting from a roof, the first-flush diverter sizing guide per the Texas Manual on Rainwater Harvesting walks through sizing the diverter to your catchment, and the water reuse tank topology guide covers banding grey-water, rainwater, and HVAC condensate into staged storage trains.
The base is the mistake to avoid
The single most common error with a tank this large is an inadequate foundation. At over 42,000 pounds full, the pad must be flat, level, and engineered for the load, with continuous support across the entire 129 x 129 inch footprint - that is roughly an 11 ft x 11 ft (10.75 ft square) pad. Read the concrete pad sizing guide for the ACI 360R-10 framework before you pour. If this tank is part of a rural or remote fire-protection reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service.
Freight
This Bushman rainwater tank ships by LTL freight from Temecula, CA, with freight quoted live to your ZIP code. West Coast and Southwest buyers sit closest to origin and ride the shortest LTL lane, a genuine cost advantage you can confirm per ZIP. A 5,050-gallon tank is an oversized load, so get your delivery quote before ordering: use the Freight Cost Estimator for an instant figure to your destination, or call 866-418-1777 and we will work out the best routing for a tank this size. The 129-inch width is the controlling dimension for gate and access clearance, so have your site access details ready, since equipment may be needed to offload at delivery.
