The aim of the water recycling is to remove the unwanted ingredients from the water and restore the natural water quality. In order to achieve the highest possible quality of the water, I take a physical separation of the systems bath, kitchen and access to drinking water. Each system brings different substances into the water and in turn requires a different quality water inlet and thus treatment.

Drinking water quality is the highest requirement and should therefore organise with less risk. The generation of drinking water takes place outside of the water recycling system and is connected with the extraction of rain and remineralisation. Rainwater is produced by natural evaporation and subsequent condensation, such as artificially produced distilled water, and is therefore less polluted with possible pollutants. The water obtained by rain is cleaned and tested with various filters and can be used in the kitchen with good quality.

The water in the WATER AREA from the shower and the washing (laundry and sink) is cleaned in the water recycling system and is available after filtering as shower water again. Depending on which substances are introduced into the water as washing-active substances as well as dirt and pollutants (when washing laundry), the water is contaminated. The degree of stress affects recycling, especially in the duration of the treatment and the result. The better the washing-active substances are biodegradable the faster and better the system can work.

By limiting the filters to the targets mentioned in the focus, the system will not be able to remove all pollutants from the water. In this context, only a holistic changeover of all systems makes sense. This means that the tiny house’s household has to be switched to the use of sustainable materials and substances, so that the water recycling system can also work qualitatively well.

For the wastewater from the kitchen is the using of a prefilter and separator necessary to separate food leftovers as well as fats and oils. Contaminants in wastewater are in dissolved and unsolved form as well as organic compounds (fats, proteins, carbohydrates) which result in an (anthropogenic) increase in nutrient content, especially nitrogen and phosphorus, and thus Eutrophication.
