The Bushman 1500 Gallon Dark Green Rainwater Collection Tank is a polyethylene above-ground tank built for capturing and storing harvested rainwater at residential and light-commercial properties. It holds 1,500 gallons, stands 63 inches tall, and sits on a 94 x 94 inch footprint, so it answers the first question any buyer has - will it fit and will it hold what I need - before you ever pull a tape measure. The dark green exterior holds back sunlight to slow algae growth in stored water, which matters when the same captured rain feeds irrigation or a fire-water reserve through a dry season.
Specs at a glance
Capacity 1,500 gal · Full water weight 12,510 lb · Footprint 94" x 94" · Height 63" · Specific gravity rating 1.0 · Material polyethylene · Color Dark Green. These are the load-bearing numbers your pad and foundation get designed around - measure the technical drawing on this page against your site before you pour anything.
Will it work for your site?
This is a 1.0 specific-gravity tank, which is exactly what rainwater needs - water weighs 8.34 pounds per gallon, and at the 1.0 SG rating this tank is matched to clean water and dilute, water-like contents. Filled to capacity it carries 12,510 pounds, so the pad and ground beneath it have to be engineered for that load, not estimated. Plan the base before the tank arrives: a level, fully supporting foundation is what keeps a poly tank from stressing at the seams over years of fill-and-draw cycles. Our concrete pad sizing guide walks the ACI 360R-10 framework for sizing that base to the 94 x 94 inch footprint, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 1,500 gallons is the right capacity for your roof catchment area and demand.
Harvesting and reuse done right
A rainwater tank is only as good as what reaches it. Size a first-flush diverter to send the dirtiest initial runoff to waste before it enters the tank - our first-flush diverter sizing guide works the math per the Texas Manual on Rainwater Harvesting, 3rd Edition. If this 1,500-gallon tank is one node in a larger grey-water, rainwater, and HVAC-condensate reuse system, the water reuse tank topology guide covers quality-banded storage trains and treatment sequencing. For rural sites holding this tank as a private fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection for cold-climate service.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation and over-trusting a slope. At 12,510 pounds full, a soft or settling pad lets the tank lean, which puts uneven stress on the tank wall - build the base to fully support the whole 94 x 94 inch footprint, not just the perimeter. Don't treat this as a chemical tank either: it is rated for water-like contents at 1.0 specific gravity, so keep it on rainwater and irrigation storage duty, not denser fluids.
