The Bushman 265 Gallon Black Slimline Rainwater Storage Tank is built for sites where ground space is tight but rainwater storage still has to happen. At 25 inches deep, 59 inches wide, and 62.5 inches tall, this slimline water storage tank tucks against a wall, fence line, or between a house and a property line where a round tank would never fit, while still banking 265 gallons of harvested rain. The black polyethylene wall blocks light to discourage algae growth, which makes it a practical choice for outdoor rainwater storage that sits in the sun.
Will it work for your site?
This is a 265-gallon water storage tank with a 25.0 x 59.0 inch footprint, so a level pad has to cover that full rectangle, not just a circle. It is built from polyethylene and rated to a specific gravity of 1.0, which is the rated ceiling for this tank and is exactly what water and rainwater service ask for, so there is no heavier-contents version to step up to here. Plan your support pad and overflow routing knowing the load involved: at 265 gallons of water, the tank and its contents reach 2,210 pounds, which is also the maximum rated contents weight. That is the figure you hand to whoever sizes your foundation, and it has to be carried by a flat, fully supported pad. If you are still working out how much storage your roof catchment justifies, run the numbers with our Tank Sizing Calculator and read the Tank Sizing Guide before you commit to a footprint.
Designing it into a rainwater system
A slimline tank earns its keep as part of a planned harvesting setup. For roof-water capture, size your first-flush diversion alongside the tank using our guide on Bushman rainwater harvesting and first-flush diverter sizing per the Texas Manual on Rainwater Harvesting. Because a full tank carries 2,210 pounds onto whatever it sits on, set it on a properly sized pad; our walkthrough on concrete pad sizing for above-ground polyethylene tanks covers the engineering boundary. If you are aggregating rainwater with other reuse streams across a property, our piece on industrial water reuse tank topology shows how rainwater storage fits a larger storage train, and rural fire-protection users should review fire-water reservoir tank design for rural and remote sites.
The mistake to avoid
The most common slimline mistake is treating the depth dimension casually. At only 25 inches deep but 62.5 inches tall, this tank is narrow front-to-back relative to its height, so it is more sensitive than a squat round tank to an out-of-level or partially supported base, and it is more exposed to wind when empty or run low. An uneven pad concentrates load and stresses the wall. Confirm the full 25.0 x 59.0 inch footprint sits on a continuous, level surface before filling, and consider sheltering or anchoring the tank against wind while it is empty. For exact inlet, outlet, and overflow fitting positions, see the technical drawing on this page.
This tank ships LTL freight from the Temecula, CA plant, with cost quoted live to your ZIP code. West Coast buyers get the shortest lanes; East and Midwest destinations should expect longer, costlier hauls, so check your number before you buy.
