It’s official; it’s a cover up. That is to say that the septic installation is covered up leaving just the power connection and 3 stages lids visible.

Not sure if the white thingy in the picture below is a spray head or an air outlet, but we will see.

The contractor informed me that it got inspected and approved also, so I should be good to go. Literally… 😉 

See the little pinkish puck on the picture below? That’s one of the spray heads, that during the night, after purification, spray the excess water onto the land.
