Feedback please tank rainwater

Re,

pseudomonas, is it so difficult for you to answer the questions that we ask you ????

clear and precise question to pseudomonas and Forhorse:

are you registered as a member on my site ??

..

[Christophe]

But in 10-12 French departments, less than 700 liters of water per m2 fall. I would be curious to know the impact it will have on them.

Very little...

Find the land use figures and you will have the more precise answer ... I think that the occupation of housing construction represents less than 0.1% of the land use at the level of a region ...

Google is your friend...

[pseudomonas]

@Pierrot: not save. Why ? you filter your information according to the status of the user ... personally, I do not register to get info. Downloads, please, a forum obviously ... but to access information simply ... blah!

for the second question, yes I will ask for rainwater recovery but to connect it to the general rainwater recovery network in my municipality, this will go into the retention basin if I understand correctly. question of storing it. For my flower beds, I only put perennials and I no longer have fleet concerns. Regarding the garden, the water supply is buried via a perforated plastic tube. (the vegetable patch is small). Low flow flush.

[pseudomonas]

Christophe in the 10-12 departments, you have essonnes for example. I think 0.1% is not the right number.
I do a lot of research, links on this thread I think ... I know google well thanks;)

[pseudomonas]

@Christophe: for the forum, it might be nice (but I don't know if you have the possibility to do so) to display if such a member is online or not in the left column. This would allow you to respond faster (since Pierrot gets upset when you don't answer him within 5 minutes!).

Re,

clear and precise question to pseudomonas and Forhorse:

No and I don't see why it should be done.
If you are looking to promote a technique, I do not see why you should register for information on it.
On the contrary, everything should be accessible easily and by all (with the "disclamer" which goes well) at least for what is reliable and verified (at the limit keep for you and your members the "experiments" and projects)
What is the point of imposing a registration to access the site? The recovery of rainwater is therefore reserved for an elitist club which does not want to share its knowledge with the common people?

Personally before registering on a site I verify that it is valid, that it contains at least interesting information. What I saw on yours didn't make me want to go any further.
Again, it's not by limiting access to information that you promote a technique.

Hello,

But I would be curious to know what is the proportion of pavilion roof compared to the total surface of the country, compared to that of roads, large parking lots and industrial and urban roofs which are poured directly into the river.

From memory, in 2007 in France there were 11000km2 of built surface, and 17000km2 of roads and parking.

In addition, out of 30 M of housing, there are 10M of houses, and each house is on average 100m2.

Without procrastinating on the number of floors, we therefore have a maximum of 1000km2 of roofs for houses, on 550000km of territory ...

[bernardd]

For rainwater, I knew a farm with 2 tanks of 25m3 for rainwater, and everyone drank there without problem before running water.

But natural protection was also better: animals, cheeses with independent movement, and ... water in the wine :-)

Today, it is not bacteria and other ferments and viruses that should be feared: it is the oil dust and the pesticides and herbicides deposited on the roofs and washed by the rains that are harmful ...

This morning, I heard on the radio that a recent ad hoc study had looked for this type of product in the discharges from purification stations: they are not filtered, like hormones, and were not even looked for, easy ...

So they go in the tablecloths. But are they only sought after in tablecloths? What about supposedly potable water?

Finally, rainwater on a clean roof may not be bad

[pseudomonas]

But Bernard, metals, pollution in general, pesticides will also be present in your rainwater. It doesn't change anything. Only the medocs will not be there.
And when it comes to natural protection, we didn't live better before! so look at life expectancy.
Before, we punctured faster, easier! natural selection at all stages of life was much rougher!

Re,

@ pseudomonas and Forhorse;

That is what I thought ...

as I said before, it is all very well to disparage, but you have to know what we are talking about!

nothing concrete ???
nothing "practical" ???
that blank ???

hey hey .. let me laugh ..

so that things are clear, before judging what i will say, i took the trouble to ask you the question of knowing if you had read everything from my site or not, because before denouncing something or someone one, the minimum of respect is to ask the adequate and sufficient questions to have sufficient data to judge well ...

what alas, you did not do ...

indeed, you could not read the whole of my site, since you did not bother to register there.
therefore, you have not been able to read my most important articles on the subject, the most "practical" and the most concrete articles .. !!

so before judging people the way you do, at least take the assurance of knowing if what you denounce is confirmed or not .. !!

now, for the fact of having to register on my site to access the essentials, I have no accounts to report to you, but I will explain it anyway: (even if I know in advance that it will not suit you ..)
1) my site is a site specialized on a (vast) field: water
2) on my site, there is "general" info, various articles, and .. my personal items !
"my" personal articles are the result of multiple approaches, research, experiments, field practices, which "I" have carried out for several years and at my expense ...
these items are invaluable to me, and enough direct "feedback" from site members allows me to appreciate the quality and value these have for "searching people".
3) those who read my site "by the way" without particular interest for the subjects mentioned "just pass" and read what they want from what you see at first glance ..
4) those who arrive on my site "by particular interest" come to seek precise information on these subjects, without necessarily being satisfied with the "general" information.
et these "people looking" for specific info (for their personal project, for example) will quickly go to the trouble of validating a nickname and an email to consult the essentials ...
(it's not trivial that there are nearly 1200 members registered on my site.)
5) these personal and concrete articles are especially intended for those who are most interested in it, because it is the sharing of direct experience, what most project promoters are looking for ... not really for those who spend their time to disparage what they don't know well ...!
6) "these people who are looking" have noticed that on the welcome insert it is mentioned that the registration gives access to all the information and articles and photos.
7) registration is obviously free and free, therefore only depends on the interest of the visitor ...

QED

A demonstration would be the publication of the results of the analysis of the water in your tank, the bacterial evolution in the places where you use it, and finally what you use to maintain the bacterial level of this water, without UV, chlorine free.
A more rigorous approach.
Talk about facts, concrete, without putting anything in your answer, leaves me to think that it is blank.

know dear sir that the "demonstration", I have been leading it for a few years in the field, and that if you were sufficiently open and interested in the subject, I would gladly invite you to come and see all this for yourself at home or elsewhere, to come and consult the analysis results here in private (*), to come and check for yourself the quality of my water where you would like it, to come and taste my drinking water ..., but alas, I know in advance that like the other critics / denigrators to whom I have already offered this invitation, you will not bother to follow up ... as usual ...

(*) = you must know (I suppose) what the water analysis costs in a specialized laboratory ..., then me, a small individual that I am, I cannot finance all these analyzes alone .., therefore, allow me (for now) my dear sir to keep these results confidential, except of course for the co-financiers who allow me to carry them out, and for the health authorities when they will take the trouble to compare them ... !!

So after, obviously, on your site, we see that all this is your hobby. I'm not necessarily a fan of your DIY to make your own compost with recycled pallets and chicken wire but you believe it.

this remark shows a certain narrowness of the vision that you carry on the subject ...

So I come back from your forum Pierro: and it's still weak both in terms of attendance and technical explanations.

mon forum is just a complement to my site, just as specialized on the same subjects ...
it has no other claim, and I prefer "little concrete" than "a lot of anything" ...!
and since the subject does not suit you ... just go your way, you will save time !!

What is your exact training on this subject?

passionate autodidact !!

Regarding your process for containing bacteria? What is that ?

sorry ... you missed the answers ....

Regarding rainwater, I think it's an anerie. sorry.

well it is your opinion, and I respect it, but do not prevent me from asserting that it is based on far too few fundamental elements which gives you a completely wrong vision ...

On the one hand, we are going to be told that we are going to consume less water and then by reflecting for 2 seconds ... water from the public network, where does it come from? What will be the impact of massive use of rainwater tanks for groundwater?

"thinking about it" .. ??
well if you had a little more concrete data ... it would allow you to think differently .. !!
because you denounce once again something that you have not studied in depth besides your "assumptions" ...

if you had browsed my "modest" forum a little more, you would probably have read an explanation of the fact that at home, by a simple but good design, my installation allows an "effective infiltration" perhaps doubled compared to the natural infiltration of the rains ...

you can find this explanation this way ...

and on the references that you cite, I do not see a rate of natural infiltration of rain, which is still important to know, since little more than 40% of what falls on the ground !!

and it is not by trying to know the waterproofed surfaces in any way everywhere that we can objectively determine if a private installation will or will not be "harmful" ..!

But in 10-12 French departments, less than 700 liters of water per m2 fall. I would be curious to know the impact it will have on them.

yeah but once again, before denouncing things "that we would be curious to know" ... it would be better to make the effort to learn them !!

yes I am going to put a rainwater recovery but to connect it to the general rainwater recovery network of my town, this will go into the retention basin if I understood correctly.

then there is the sppon !!!
well done !! , the opposite of common sense !!!

But Bernard, metals, pollution in general, pesticides will be present also in your rainwater. It doesn't change anything. Only the medocs will not be there.

"as well" .... ( ) Yes ...
so what ???

and to answer your other answer: if this is all you plan to do with your rainwater and the little (nothing) that you currently practice ... thank you for not looking to teach me about this subject ... !!
