The Bushman 3000 Gallon Green Rainwater Collection Storage Tank is a polyethylene tank built for serious rainwater harvesting and bulk water storage. It holds 3,000 gallons on a 102-inch (8.5 ft) diameter circular footprint and stands 97.5 inches - about 8 ft 1.5 in - tall, so a single tank captures a meaningful volume of roof runoff without sprawling across the site. The green color helps the tank blend into landscaping and limits light penetration, which discourages algae growth in stored water.
Will it work for your site?
This is a water storage tank rated to a specific gravity of 1.0, which matches fresh water exactly - the right rating for rainwater, captured roof runoff, and general non-pressurized water storage. Filled to capacity it carries 25,020 pounds of water, and that is also the maximum rated contents weight, so plan the foundation around a fully loaded tank. Because the SG-1.0 ceiling equals the as-water load, this tank has no contents-weight headroom above fresh water - a point worth holding onto when you choose what to store. The footprint is a 102-inch (8.5 ft) circle, so an above-ground polyethylene tank of this size needs a level, fully supporting pad sized for that loaded weight across the full 8.5-foot diameter plus working clearance. Our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that base right. To confirm 3,000 gallons is the correct volume for your catchment area and demand, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Rainwater harvesting and fire-water service
For a harvesting system, sizing the storage tank is only half the job - the first-flush and inlet hardware determine the quality of the water you keep. Our guide to first-flush diverter sizing per the Texas Manual on Rainwater Harvesting covers that hardware in detail. A 3,000 gallon reserve also makes this tank a candidate for rural and remote fire-water storage; our fire-water reservoir design discussion works through NFPA 22 sizing discipline and freeze-protection for cold-climate sites. If you are aggregating grey water, rainwater, or HVAC condensate into a reuse train, our water reuse tank topology guide shows where bulk storage like this fits in the sequence.
One mistake to avoid
This tank is rated for a specific gravity of 1.0 - fresh water - and, as noted, has no load headroom above that. That makes it correct for rainwater and water storage, but it is not a chemical tank. Storing a liquid heavier than water (any solution with a specific gravity above 1.0) exceeds what the wall is rated to hold and is the most common sizing mistake on a tank like this. Match the contents to the 1.0 rating and you are within spec. One more planning note: fitting locations and sizes are configured at order, so confirm inlet, overflow, and outlet placement with us before shipment to be sure your fittings line up with your gutters and distribution at install.
