that's exactly it Jonule, replace the traditional detergent with the soap nut, a month ago I saw an advertisement on the soap nut, in addition they say that for 1 kilo of soap nuts you have for 1 year of washing, the other time in the store I went to see the soap nuts, I was not too tempted I felt the inside of the bag it did not make a good impression.
But hey if it allows you to recover your washing machine water, on the other hand if this water is intended for the toilets no problem, but for the vegetable patch, there will be a small problem, the water that comes out is boiling.

you talk about 150 to 200 liters per detergent, you even dump an old washing machine it will take only 60 liters per detergent.
I have a machine that takes 48 liters per detergent and I do almost 1 detergent per day, so it makes me 1440 liters per month, I suppose it can supply me with a vegetable patch?

Flytox, I have the whole in the sewer, so there is no problem to make soapy water in the flush, the only problem will come from the tank of the flush, there is the flush rubber + float valve mechanism etc ... which if corroded with soapy or greasy water may break.

Ahmed, it's a double drainage system that I have to find, for the washing machine it's the simplest, on the other hand for the sink, the sink (the bathtub I drop it is too dirty ) this is where it will be more complicated, at first glance I would say I would put a double evacuation system with directing valves, yes because outside I will put a container to recover, and if the container is full, while I use, the surplus water will have to be evacuated in the conventional way.
I did not understand "legal obligation"
Yes the solution is before reusing the water, putting filters, and is it playable?
Because when we throw away all of our wastewater, after the Lyonnaise des eaux collects the water, the filter, etc., but they are more complicated because the gray water is mixed with the wastewater.
while in my case will filtration cost me dear?

the soapnuts contain a soapy substance, that's what you smell: just pass them under water and shake them to see that it lathers ;-)
on the other hand for a satisfactory use, it is necessary to use stain remover of washing (the active oxygen of the pubs) which you also find in organic store.

finally there are other "bio-compatible" detergents, I use a "magic ball", 40 € for 1000 washes, it works well for everyday laundry.

pure boiling water, just let it rest a little, and it allows decanting, it will be even more clean ;-)

I swear to you that she recovers as much as I asked her, she must use prewash wash rinse etc etc? ... I asked her it's a class D she is 6 or 7 years old, spins at 400 rpm, consumes a lot of electricity etc ... it's true a new one is rather 50L now ...

@ Kangaroo:

It is necessary to transplant yourself to the drain so as to direct the effluents to your tank: all you need is a single valve to close your tapping and force the water to take the old route.

"legal obligation": the company that supplies you with the water is responsible for the quality of what circulates on its network, it therefore scrupulously ensures that no water not controlled by it can contaminate it.
The two circuits must therefore be separated.
It is possible to satisfy this obligation by having a double tap, or, what is simpler, by inserting a non-return valve on the city water pipe.

Filtration is a technical necessity, because otherwise the taps will not work for long.
The filtration system can be tidied up quite simply: you need a gravity grease separator (it is a tank with a middle wall letting the water pass from below and blocking the fatty substances floating on the surface), plus a filter sand to retain suspended particles.
It remains quite rustic, since there is no pressure at this level. If that puts you off, there remains the option of rainwater…

For the filtration of my well water I use a textile cartridge filter placed after the pressure tank.

Ahmed, by any chance you wouldn't have filter photos.
otherwise I think if I start it will be with the washing machine, because the evacuation is almost a breeze.
then I will have to filter the soap a little, how long does a filter last?
and then the valves I saw on the taps, but on PVC drain pipes I never saw any

for rainwater it does not tempt me too much, already I have no well, I have small gutters, and then it's not regular, there for July and August we had drought, while the washing machine is everyday.
On the other hand, the water that I will recover will still be dirty, and it will stagnate in a container, at the microbe and battery level, to remove any risk of disease or proliferation of microbe, should I add chore?

Jonule, for your machine with 400 spin cycles and 200 liters per detergent, throw it away immediately it's a fortune, in addition with a spin of 400 turns, the laundry dries in 1 week!

well that's what i told her but she told me that a new one is 400 € and that for the moment it allows her to water her garden at a low price, because the water from her city ​​is!

otherwise the linen water does not normally contain bacteria, and still contains detergent ... so no chlorine. you can already observe before making a decision, but once in the soil, it degrades and nourishes your soil.

Sorry, no photos available, but it must be on the net…
The duration of the filters is great, it is their cleaning which varies in frequency according to the turbidity of the water and the quantities filtered.
"… The valves I saw on the faucet, but on pvc drain pipes I have never seen."

Exact, but it must be possible to use valves that go on copper pipes, even if it means using PVC / copper screw fittings.
"... I'm not too keen on rainwater, I already don't have a well, I have small gutters, and it's not regular, there for July and August we had drought."

I don't quite understand the argument of the lack of wells?
For the rest, I agree, the rainwater supply is, by nature, irregular, which is why this solution requires a fairly considerable storage volume. However, even with a modest roof surface, one is surprised at the quantities of water that each rain is capable of generating.

Elephant explains that the detergent contains chemical fertilizing elements, it is true but there are also undesirable elements and I agree with Jonule to limit these products, preferably for use, if not by decantation-filtering.

and if I only collect shower water in a tank that I will place in my basement and that I use this water only for watering the garden, there are also soaps there that can for a certain at least avoid germ problems? !!

it all depends ... on soap and microbes! : Cheesy:

for valves, it exists for PVC, up to diameter 100, and even in solenoid valve (expensive).

if I may allow myself regarding soap nuts !

found on another site (sorry christophe!)

"Wash nuts"
Do not repeat the mistakes of the past!
We have seen arriving on European markets in recent years,
a new “miracle product”: soapnuts from India
that we use as well in detergent as in soap or shampoo…
What is it about ?
Nuts produced by “soap trees” (Sapindus Mukorossi), currently wild, in certain states of the Indies (Imachal Pradesh for example).
A serious and well-known company in fair trade, tells us that a "collector" buys the nuts from the farmers, after manual picking, to resell them to a wholesaler who will help supply local demand (by incorporating these nuts in detergents chemical).
That the Indians of these states thus have an accessible, relatively ecological, very good washing product.
Developing this economic activity to provide a European market (which does not require so much!) Poses certain ethical, economic and social as well as ecological problems. Indeed, the local economic, social and humanitarian consequences in the very short term are perfectly predictable:
development for the export of a wild food resource
cultivation, without local or regional necessity
tendency to export monoculture (quinoa, coffee, tea, sugar…) and regional imbalance
loss of similar resources in importing countries (the saponary in Europe, for example).
perverse effect of a “fashion”, of a “trend”: all the more so since these soapnuts have a result that is significantly distant from our European detergents produced locally and harmless to the environment… When the boo-boos have had enough soapnuts what will be left to the Himalayan Indians…? Immigration to 9-3?

The importation into Europe of these soapnuts (with the ecological aberration that constitutes its transport) is exactly the false "good" idea that can be compared to neo-colonialism.
In this perspective of ecological coherence, the Asphodel Salon was the first to ask its exhibitors not to present this product there ...
NB1. You are going to tell us: why the soapnuts and not the tea or coffee or ... the solar collectors made in China. We will answer: we have to start thinking about it with a bit… and as long as we do not repeat the mistakes of yesteryear!
NB2. We also learned that France had once planted soap nut trees in its colonies (Asia and Africa) ... But only the climate of India gives these nuts relative washing power. So when a French reseller tries to justify himself by specifying that his nuts come to him… from Africa, we measure the fashion effect of the product even more!
Marie Fougère and Jean-Marc Carité


The House of Ecology sharing, the analysis made by Marie Fougère and Jean-Marc Carité (from the UTOVIE Edition and the Salon Asphodèle show), joins this call and dereferences the soap nuts from its catalog and its sale in line

there is no harm, we must avoid mono culture.

in addition, the tree grows in France I offered seeds which germinated to my sister who lives in the South ;-)

I also and above all use the Magic Ball, do you know Hasardine?
