Adam moves into the drainage trench

After the septic tank burial Adam now turns his attention to the 12m+ of drainage trench. Luckily its much shallower than the septic tank, being a simple perforated pipe in gravel.
Bizarrely all the old shack had attached to its loo was a rough old soakaway, barely buried. And for 40 odd years it seems to have worked, we expected to uncover something very grisly in the recent excavations but so far so good.
