Chambers for the septic tanks and absorbers are coming together.
The septic tank treats the material then transfers the resulting liquid to the absorber. Liquid in the absorber slowly seeps into the ground through its porous walls. Et voilà.
The main septic system.

Prepping the formwork for the concrete slab which will close the absorber.
The concrete slabs will then be covered with earth and grass blocks.
The two larger pipes are capped flush with the finished ground. They will be used to inspect the septic tank about once a year.
The third smaller pipe is for ventilation and will run underground to the side of the house where it comes out and is capped with a T connector.
We decided to create a second septic system for the workshop. Those chambers need to be about 3 meters underground because the relatively low placement of the toilet in the workshop.
