Here is the final step of prep work on the tank–the netting has been completed and backed (or formed, as we say in the business) by foam batts (another technical term) ready for the rendering. Also, Roland thought we should record everything, including the septic tank installation, so we know where it is later!–makes sense. I can just see me putting the grubber through the lid of the septic tank, nothing more likely. So here are a couple of shots of the installed tank, and the line to it from the house, with a post marking one of the IPs (inspection points, as above. . .) between the shed and the tank.
