Rainwater: my experience 14m3 family 5 people

[dede021385]

Hi tran,
I dig up the subject slightly but I'm also going to make a water recovery system to supply my house.
By cons I have a source in my crawlspace.

For your odor / bacteria problems there is a simple, quick and ecological solution: o3 or ozone.

It destroys all, the smell is not unpleasant and it is not toxic to humans (except in very high doses)

I recommend this treatment system

I currently use it in my crawlspace which is very humid and smells very bad, now it is healthy.

On the property I occupy there is a very large rainwater collection basin from the roofs (about 150 m3, maybe more). It is mainly used for watering or as a reserve in the event of a summer fire. In addition it is slightly in height which facilitates the use of water by gravity.

It is open and collects a lot of leaves, resulting in a vase that develops on the bottom, but the water remains clear.

Do you think it is possible to use this water for household use (washing machine, wc) with special filtration?

What type of economical and easy-to-install filtration could be suitable?

Installation (replacement) of the cover last September:


The reserve is currently overflowing (photo taken in early February):
I put some floating objects (pallets, boards) because unfortunately animals fell into it and could not get out.

with a floating strainer (to avoid sucking bottom sludge) and filtration by polypropylene cartridges (I have 25µ, 5µ and 1µ in series) that should do it ... If you are not looking too much at it 'smell that water could have ... Yes, your filters will clog quite regularly. A good idea would be to be able to reverse the flow from time to time with clean water and send the residues to the sewer. Put your filter cartridges away from light. Of course avoid drinking water (I only drink mine in tea or noodle cooking water, it never made anyone sick), we wash with dishwashing and washing with dishwashers ..... After this is my modest experience of 35m3 / year or barely 1/4 of my normal consumption.tu can also have two sets of cartridges including one soaking in a 10l jar with three bleach tablets while the other is in use ... For the filter holders and cartridges at aquabievre and tec2o we get to have interesting prices. .For critters who come to drown ... it's not cool the corpses of pigeon rats and others are not very holy stuff ...

Hello

My feedback on the subject in the Brittany region
A 7500L plastic tank for the house (another 1000l for the garden)
I just have a pre filter (pool) plus a filter at the inlet of the tank and a last on the strainer (on float).
I currently supply toiletries (no dry toilets yet), washing machine and dishwasher with 6 people at home. I think it represents half of my consumption (50-60m3 per year)

It happened to me 2 times in 5 years that the tank is empty and to switch to the network (for a week max) and at these times there, at the bottom of the tank, the water can be a little earthy.
Otherwise, the water is always nickel and odorless (sometimes drunk by mistake by my children).

I still have to connect a roof of 25m2 to increase the recovery capacity and the idea would be to switch the hot water and the water from the showers.

.After this is my modest experience of 35m3 / year or barely 1/4 of my normal consumption

I find it very interesting that a few notions of size appear over the posts…

The overall water use of an “expert econologist” would therefore be 35 x 4 - or 140 - cubic meters / year, in other words 12 m3 / month or 384 l / d

I am not even a “beginner econologist” (so a lot of progress to make !!), but I have never managed to exceed in total (at 3, with washing machine, showers, etc.) 24 m3 / year either 2 m3 / month or another 66 l / d. Without depriving me, just with a minimum of attention ...

Like everything is relative, and if everyone accepted a minimum of questioning, the world would easily get much better !!!

Like everything is relative, and if everyone accepted a minimum of questioning, the world would easily get much better !!!

Of course, but beyond individual questioning, there is also a whole environment which makes it simpler and easier to consume-waste than to save.

An example for water: I live in a region (Provence) where there are probably the most swimming pools per m2 in all of France.

I randomly took a simple area of ​​my municipality of 9000 inhabitants: count the number of swimming pools. (Note that there is a communal swimming pool!):


Each year, in the spring when the swimming pools are replenished, hundreds of thousands of m3 of "clean" water are released into nature because the use consists of emptying the wintering water on the public road to fill with potable water. In a few weeks, as soon as the weather is fine, for days the gutters of the residences will drain the water from these swimming pools.

And the paradox is that these swimming pool owners have also, for the most part, installed rainwater collectors and water saving accessories ...

It would almost be necessary to install a secondary water recovery network in parallel with the supply network.

For almost two years we have been living at 8 on the announced water consumption ...
2 families of 4 ... 4 adults 3 addos 3 mats 40cm long ...
We do not have a swimming pool, we only take showers with reduced flow (no curtain, no cabin) ... The consumption of my household normally fluctuates between 60 and 80m3 annually ...

A yes we all take a shower a day I do not water the garden and I do not wash my cars ... I am also surprised by this consumption ... but to arrive at 25m3 years ... Even when we lived together we typed in 40m3 ..

Hello,
I am at the origin of the first message of this thread.
Recently, I installed a rainwater meter knowing that the town will, normal and civic, charge for the treatment of wastewater.
Rather than an "estimated" package, I can therefore argue our real consumption.
In addition the meter is equipped with an electrical sensor which allows me to know precisely the volumes consumed hour by hour.
For a household of 3 people, I arrive at 7000l / month.
Rainwater is for us a comfort that allows us to take advantage of long showers heated by solar, of course.
In terms of odors, not the least for 8 years.
I now plan to drink in order to become independent.
For the moment it is the municipality which collects the invoices which do not bother me, but if like many others this service is privatized I do not want to become a cash cow for shameless shareholders. Just look at what has become of our public services.
Spring water is billed at 3 € by the neighboring village, while suplus spring is used to make artificial snow or is simply poured into torrents .....
I react to the storage of one of the participants: storing open water seems to me a very bad idea if we want to use the water for other purposes than watering and toilets unless to have a complex treatment downstream. (American system, we accept pollution then we clean up)
Water stored in a cool place, protected from light, good upstream filtration, makes it possible to have quality water with ease (provided that it is in an area not too polluted)

Hello,
Following my experimentation, for 3 years now we are 100% autonomous in water.
The drinking water is provided by a Doulton ceramic filter followed by a non-return valve and a 5l sanitary bladder tank.
Thanks to the reservoir, a normal flow is obtained at the draw-off points.
The water has been analyzed by a Belgian laboratory (more objective) the water is completely drinkable.
