Hubby calls it a cigar.
Actually it's a septic drainage pipe...though I don't know the technical term for it. Hubby has been working on two septic systems the past couple of months (wet weather delayed both projects) and is finally managing to finish the last one; a septic system for a church just down the road from us.
Anyway. He chose to use this kind of drainage pipe for the systems. The black pipe at the center has holes in it to allow for water to leech out of it. The Styrofoam peanuts in the netting around it prevent dirt from filling in the holes and allow the water to escape. You can't see it in the picture but there is a sheet of papery stuff on one side of the "cigar" that must be positioned on top when the pipe is laid in the ditch; this prevents dirt from filtering down through the "peanuts."
If hubby had decided to use just a regular pipe he would have had to haul loads and loads of gravel to put all around the pipe before and after he laid it. So the "peanuts" save lots of fuel and wear and tear on the dump truck.
