It goes with the water that leaves your septic tank.

A septic tank is only meant to separate the water from oils and sludge.

Really? So all my piss goes right thru and into my yard? If it filters out and stores solids wouldn't it also catch the microplastics too?

Depends on where you live. Mine goes trough the septic tank towards the sewer. A lot of houses also just go directly to the sewers.

And no, many microplastics are too lightweight to settle with the solids.
