The Bushman 250 Gallon Plastic Vertical Rainwater Harvesting Tank (SKU BM-30219) is a black polyethylene vertical tank built for residential and light-commercial rainwater harvesting. It measures 66"H x 36" diameter and holds 250 gallons in a compact 36-inch round footprint, so it fits tight along a wall, beside a downspout, or in a side yard where ground space is at a premium. The black wall blocks light, which slows algae growth in stored water - a real advantage over translucent tanks for outdoor harvesting.
Will this 250-gallon black water tank work for your site?
At full capacity this tank carries 2,085 lb of water, which is also its maximum rated contents weight, so plan your base for that load across the 36.0 x 36.0 inch footprint. Built from polyethylene with a 1.0 specific gravity rating, it is sized for water and rainwater - the mistake to avoid is using a 1.0-rated vertical rainwater tank for anything heavier than water. This tank is not rated for dense liquids; rainwater service is exactly what it is built for. If your application calls for a denser liquid, that is a different, higher-SG tank - not this one.
Fittings and field plumbing
The fitting package shown on the technical drawing includes two flat fitting pads (an 8" x 7" and an 8.5" x 6"), a 3-inch outlet and overflow kit, and a 1-inch bulkhead fitting in polypropylene with an EPDM gasket. The PP/EPDM combination is the correct sealing surface for water and rainwater service. If you add your own plumbing, match connections that preserve those polypropylene and EPDM sealing faces, and confirm exact fitting locations and sizes on the technical drawing on this page before you set your outlet, overflow, and inlet routing.
Sizing and setting a proper base
For first-flush diverter sizing and matching tank volume to your roof catchment area, work through our Tank Sizing Calculator and the Tank Sizing Guide. Our guide on Bushman rainwater harvesting and first-flush diverter sizing per the Texas Manual on Rainwater Harvesting (3rd Edition) walks through the standards that matter, and rainwater harvesting tank sizing by state ties rainfall and local regulations to real SKUs like this one. A vertical tank this tall needs a level, fully supported foundation under the entire 36-inch round base - point loads and unsupported edges are the most common cause of stress cracking in field installs. Our guide on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework so your pad carries the full 2,085 lb without flexing.
Freight and how to order
This tank ships LTL freight from the Bushman plant in Fairfield, Texas, with the cost quoted live to your ZIP code - because it ships from a single Texas origin, distance is the main driver of your number, so a Texas buyer and a coastal buyer see very different quotes. Get an instant figure through our Freight Cost Estimator, or call 866-418-1777 to place an order and confirm delivery details. List price shown is before freight; freight is quoted separately to your destination.
