Vitrified clay sewer pipe is still laid today, though as a DIY homeowner you probably won't be choosing this for your sewer line replacement. It's heavy and hard to cut. Often, your choice of sewer pipe is dictated by what your home improvement store has on hand, and they won't have clay pipe.

As Logan Clay (a major manufacturer of clay pipe) points out, the material used for clay pipe is "inert," making it highly resistant to chemical degradation. After all, if you're going to be installing a product in the earth, what better than a direct product of the earth?

One downside of clay sewer pipe: roots love to attach to its porous surface.
