For a long time, I have been tickled by the idea of storing my rainwater.
But until then, for significant volumes (such as 10 m3), the prices were very high. Like 2 euros ...
I have just discovered flexible PVC tank offers at 600 http://www.la-citerne-verte.com/recuper ... .htmleuros for 10 m3:
Of course, it takes up space, and it's ugly!
I have room.
And I think of integrating it by surrounding it with a wooden cladding + above a frame of slats (like carport) planted ... We will only see fire!
And with that, I will be able to garden without scruples (watering with drinking water stressed me a little ...). The increase in my production should reimburse the tank ... And even, finally, maybe set up a greenhouse (in which watering is compulsory!).
Luckily, my garden is far downstream from the house. So I will be able to position the tank halfway: low enough for rainwater to rush in without pumping; and high enough in relation to the garden to hope to install a very low pressure drip (even if it means exaggerating the connection times) ...
Storing rainwater: finally an affordable solution?

flexible non-food PVC, therefore with phthalate as plasticizer ...
at my house I’m cheaper: a 1,2m high sheet metal circle like an above-ground swimming pool ... the sand bottom, and a polyethylene sheet for greenhouse to serve as liner
no cutting and welding, it just makes creases on the vertical walls
plastic for greenhouse being available in 8m wide it allows to make large tanks
polyethylene for greenhouse is of much better quality than that for silage tarpaulin which is too biodegradable
this tank is in the open air ... the water is always green ... the tank has been there for 20 years polyethylene is always good at the bottom ... it starts to fall apart above where it is discovered when the tank is not full
by making a tightly closed roof, the polyethylene would no longer take the sun and last even longer, and the water would remain clear instead of always being green

I looked at the "silo" side in rimmed corrugated iron ... Not found that cheap!
After, obviously, in the recovery solutions, for those who have opportunities, it is sure, it is even cheaper. There are also the tanks of petrol stations which disassemble (it closes every day), degas ... For those who have an opportunity ...
Indeed, there, the PVC is indicated "food". However, to water my garden, traces of phthalates may be adsorbed / destroyed by the soil. Between the children's bottle and a sprinkling water cistern ...

the corrugated iron silos are too expensive! the ripple is useless: the 0,8mm flat sheet stands upright by itself without any reinforcement
it is like the above ground pools: you have to make a 20cm leave in sand between the ground and the bottom of the sheet so that the plastic which seals does not make a hernia passing under the sheet
I had recovered from an ironworker an end of sheet metal coil 1,2m wide and 0,8mm thick, I made myself a tank 3,5m in diameter which stands alone ... assembled by a row 5mm screw
and a 5m diameter pool with a rigid circle to strengthen the edge so that we can lean on it
I also made a grain silo of 2,5m in diameter and 2,4m high which holds very well without reinforcement either ... assembled by welding with acetylene
without having the chance to fall on a roll of sheet metal it is necessary to assemble by screw galvanized sheet metal of current size
it is also possible to make a round agglo wall with some concrete iron chaining to resist the push of water: it is more expensive than in sheet metal but more durable

OK !
I struggled to find a reasonable price, but indeed, it is playable!
For your information, without ads: http://www.leboutte.be/catalogue_fr_Met ... nisee.html
57 euros for 3 mx 1,5 m in 1 mm
With 3 sheets, you have a perimeter of almost 9 m, a "useful" height of 1,25 m
So a radius of about 1,4 m.
Or a volume of approximately 7,7 m3. For 3 x 57 euros. Excluding screws, plastic ... and work! Well, a big pastique like that, in one piece, it should not be given! At least a width of almost 6 meters is required.
But indeed, it is unbeatable!
To avoid algae, a black tarpaulin on it? (if I want to drip, do not block the drippers!)
Thank you, I will probably change plans!
