325 Gallon Cistern Sphere Tank

Our spheres are designed to be used as a holding tank or pump tank. Unlike our ribbed tanks, these tanks may remain in the ground when empty. However, they should not be installed in high water table or high clay areas. These tanks are furnished with manhole covers and include a molded-in elevated pump stand on the bottom of the tank.

All sales through distribution. Monday through Friday, 8am to 5pm (PST)

Bushman 325 Gallon Cistern Sphere Tank is roto-molded from premium food-grade, UV-protected, High-Density Polyethylene (HDPE).  Our 325 Gallon Cistern Sphere Tank is suitable for various applications, including pump tanks, water features, A/C Condensate Collection, Greywater Reuse, approved Wastewater applications, and many more. These Spherical Underground Cisterns can be linked together underground to allow for expandable capacity and are great solutions in cold environments where water needs to be stored below the frost line. Bushman Cistern Sphere Tanks can be buried a maximum of 24" below-grade. Our Cistern Sphere Holding Tanks come assembled with a 20" Manhole Lid and no other fittings. This allows for optimal customization of fitting locations onsite.  We also manufacture 6", 15", or 24" Manway Extensions that are available for purchase through your Dealer.
