Spherical Septic Tanks

These spherical tanks are pre-plumbed in-house for septic tank use. They can also double as holding or pump tanks with modifications.

Unlike ribbed versions, these tanks may remain on the ground when empty. However, they should not be installed in high water table or high clay areas.

Included are manhole covers and include a molded-in elevated pump stand on the bottom of the tank. In-house plumbing is provided with these units, view our product drawings for specifics.
