Before the concrete foundation and floor can be poured, the sewer
drain lines have to be put into place. The string lines in the picture are where walls
will be which will hide the drain lines and vents. This was started, however rain
and other things put a delay in the process.
Main drain line -- Far end is the "guest" bath
Kitchen sink drain going to main line -- Center is covered with dirt to keep in place
Kitchen sink drain again, but master bath drain is in trench above end of sink drain
