The Bushman 530 Gallon Mocha Slimline is built for the spot most rainwater tanks won't fit. At 25 inches deep, 86 inches wide, and 78 inches tall, this slimline footprint tucks against a wall, fence line, or the narrow side-yard run between a house and a property line while still holding 530 gallons of water storage. It is molded from polyethylene in a mocha color that reads as a neutral exterior tone, and it carries a 1.0 specific gravity rating, the right rating for water storage and rainwater harvesting service.
Does this slimline tank fit and hold what I need?
The footprint on the ground is 25.0 x 86.0 inches, so measure your run before you order - the shallow 25-inch side is what lets a slimline work where a round tank cannot. Filled to its 530-gallon capacity, the tank and water reach roughly 4,420 pounds, which is the weight your pad or base has to carry. That figure is also the tank's rated contents limit: at a 1.0 specific gravity rating, this tank is built for contents up to 4,420 pounds, meaning water and water only - it is not the tank for a heavier chemical or a fluid denser than water. The weight matters more than people expect, because a slimline puts its full load on a long, narrow footprint, so a flat, continuous, properly sized base is not optional. Our concrete pad sizing guide walks through the ACI 360R-10 framework for getting that base right, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 530 gallons matches your catchment and draw.
Rainwater harvesting and water storage use
This is a dedicated rainwater storage tank, and pairing it with the right inlet hardware is where a harvesting system earns its keep. Our guide on first-flush diverter sizing per the Texas Manual on Rainwater Harvesting covers how to keep the first dirty wash off a roof out of your stored water. If you are sizing storage for fire protection or rural reserve duty, the fire-water reservoir design guide applies the same slimline storage tank to that role, and the water reuse topology guide shows how rainwater, grey water, and HVAC condensate streams get banded into a quality-banded storage train. See the technical drawing on this page for fitting locations and overall dimensions before you plumb anything.
The mistake to avoid
The most common error with a slimline is setting it on a base that flexes or isn't fully supported across the long footprint. The load sits on a narrow 25 x 86-inch footprint - about 4,420 pounds when full - which concentrates weight in a way a squat round tank does not. Build the pad first, level it, and support the full 86-inch length; do not let either end overhang.
