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)
