The Bushman 5000 Gallon Dark Green Rainwater Collection Tank is a 5,000-gallon polyethylene rainwater tank built for serious on-site water storage — rural homesteads, fire-protection reserves, irrigation supply, and industrial water reuse. It stands 92 inches tall on a 140-by-140-inch footprint, and its dark green color helps it blend into a landscaped or wooded setting while limiting light penetration that encourages algae growth. If you are sizing a 5000 rainwater system and need real harvest capacity in one vessel, this is the Bushman 5000 water tank that does it.
Will it work for your site?
This tank is molded from polyethylene with a specific gravity rating of 1.0, which means it is matched to water and water-density rainwater service. Full of water it carries a maximum rated contents weight of 41,700 lb — that is the load your pad and grade have to support, so plan the foundation around it, not around the empty shell. The 140.0 x 140.0 footprint and 92-inch height should be checked against your delivery access and overhead clearance before you commit. Fittings shown on the technical drawing on this page tell you which job each location does: the three flat fitting pads (15" x 15", 13" x 15", and 14" x 25-3/4") are blank, moldable mounting surfaces where you site your own bulkheads or manway for inlet routing; the 4-inch outlet and overflow kit is the dedicated overflow path that should be plumbed to daylight or a soakaway so a full tank in a storm event does not back up the inlet; and the 1-inch bulkhead in PP/EPDM is the small-line tap for a gauge, level sensor, or auxiliary draw. You get defined plumbing roles rather than field-cutting blind.
How freight works
This is a large tank, so it moves by LTL freight, not parcel. It ships from the Bushman plant in Fairfield, Texas, and freight is quoted live to your ZIP code — we do not bury shipping in the list price. Delivery arrives as a single oversized piece, so specify residential, limited-access, or liftgate needs when you run the numbers, since those accessorials change the live LTL quote and a tank this size may need a liftgate or your own equipment to handle it off the truck. Run your delivery address through the Freight Cost Estimator for a real number, or call us to spec the delivery.
The mistake to avoid
Do not undersize the pad, and do not exceed the tank's service limit. This vessel is rated to specific gravity 1.0 — it is for water and water-density rainwater only, so do not store any liquid heavier than water (no concentrated chemical, brine, or high-SG solution), because the 41,700 lb full-water figure is the structural design load and SG 1.0 is the do-not-exceed ceiling. On the foundation: at 41,700 lb full, this tank concentrates a substantial load on a 140 x 140 footprint, and an uneven or undersized base is the most common failure point on large poly tanks — not the tank itself. Read Concrete Pad Sizing for Above-Ground Polyethylene Tanks before you pour. When you add or replace a fitting, match the supplied bulkhead — a polypropylene body with an EPDM gasket is the rainwater-correct combination already on the tank, so use EPDM or equal elastomer seals for any new tap.
Sizing and planning resources
Not sure 5,000 gallons is the right target? Use the Tank Sizing Calculator to match capacity to your roof catchment and demand, and the Tank Sizing Guide to work through the trade-offs. Plumb your rainwater system as one design: the first-flush diverter controls what reaches the tank, the 4-inch kit carries the overflow back out, and the outlet feeds your draw — see Bushman Rainwater Harvesting Tanks: First-Flush Diverter Sizing for the inlet side. If you are building a private fire-protection reserve, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and cold-climate freeze protection, and for multi-source capture the Industrial Water Reuse Tank Topology guide maps grey-water, rainwater, and condensate storage trains.
