Waste water treatment
Noah House handles grey water and waste water. The waste water is cleaned in three phases.
The first phase is a biological sedimentation treatment / septic tank in which sewage sludge is discharged.
In the second phase, the sewage seeps through a sealed waste bed.
As a third phase, cleaned sewage is treated with an UV sterilizer then a part of it is recycled to rinse the toilets, thereby reducing the water consumption and the surplus being drained to the garden.
The sludge and slag, remaining in the system can be removed every two years, during the due cleaning and maintenance (even composted in the area).
