The Bushman 2500 Gallon Dark Brown Rainwater Collection Tank holds 2,500 gallons of harvested rainwater in a dark brown polyethylene body that runs 96 inches (8 feet) in diameter and stands 95 inches tall, occupying a full 96 x 96 inch square footprint. That makes it a near-cubic tank - 95 inches tall by 96 inches across - so measure your gate, door, and overhead clearance before delivery day. The dark brown coloring blocks sunlight to suppress algae growth, which is exactly what you want for stored rainwater. The answer to the three questions every rainwater buyer asks - does it fit my job, what does it cost to get here, and what is the one mistake to avoid - comes down to the numbers below.
Will it work for your site
This is a water tank rated at a specific gravity of 1.0, sized for rainwater, fresh water, and general non-pressurized water storage. That SG 1.0 rating is a guardrail, not a footnote: filled to 2,500 gallons of water the tank weighs roughly 20,850 pounds, which is also the maximum rated contents weight. The rating covers liquids no heavier than water, so a denser liquid would blow past that 20,850-pound limit before the tank is even full - keep this one to water-weight service. To size a single 2500 against your roof catchment area and household or site demand, run the numbers through our Tank Sizing Calculator and check the method in the Tank Sizing Guide before you commit.
Fittings and plumbing
Per the technical drawing on this page, this tank is configured with three flat fitting pads - a 12" x 14", an 8" x 14", and a 12" x 24" - which are landing areas where your installer can mount additional bulkheads on a flat wall instead of fighting a curved surface. It also comes with a discrete 4-inch outlet and overflow kit and a 1-inch polypropylene bulkhead sealed with an EPDM gasket. EPDM is the right elastomer for ambient water and rainwater service, so that bulkhead is matched to the duty. Note the difference between a fitting pad and a pre-installed port - the pads are blank landing areas, not open ports - and confirm the outlet and overflow positions against the technical drawing before you set the tank, because relocating a bulkhead after the tank is full is a job nobody wants.
Freight and the mistake to avoid
This Bushman 2500 ships by LTL freight from the Fairfield, TX plant, quoted live to your ZIP code. It moves from a single East Texas origin, so your transit cost scales with distance from that plant - get a real number before you budget rather than guessing. Use the Freight Cost Estimator for your delivery ZIP or call 866-418-1777. The mistake to avoid on a 20,850-pound filled tank is the foundation: a fully loaded 2,500-gallon rainwater tank concentrates serious weight on a 96-inch circle, and an under-built or unlevel pad will stress the polyethylene and the fittings. Get the base right first - see Concrete Pad Sizing for Above-Ground Polyethylene Tanks. For harvesting setup, including first-flush diversion sized to the Texas rainwater manual, read Bushman Rainwater Harvesting Tanks: First-Flush Diverter Sizing. If this 2500 is part of a larger fire-protection reserve or a reuse train, the Fire-Water Reservoir Tank Design and Industrial Water Reuse Tank Topology guides map the rest of the system around it.
