<p>Septic fields used a glazed tile also. It was laid with a 1/4in
gap between joints and tar paper was laid over the top. Gravel
was then placed in the trench to about 3 inches over the tile.<br>

<div dir="ltr">My guess would be that it was another variation of
drainage tile, hence the common name of "Field Tile". Way back,
about the time the dinosaurs died off there was a lot of it used
around here. It was usually around 4" OD and 16-18" long. I
recently found some, in the process of digging a drainage ditch,
that was smaller and looked like this " <u>O</u> " a round,
hollow tube with a flat base. The hole was about 2" ID. I
never thought to salvage any of the intact pieces.

<div>It was laid, end to end in a trench, and buried. Water
could seep in through the joints as could fine solids. I
never could figure out how it could help but plug solid in
short order. </div>

It's made of glazed field tile but shaped like a big hex
nut. Never seen anything like this before. Any idea what
it would have been used for? Doug T</font><br>
