yeah, maybe not having both full then, fill the top one with rainwater, then pump through ro di into bottom one... Either way it doesnt matter i just thought it would be floor space saving, and gravity feed would help.
Theres been so much rain, shame its not all set up yet.

gotta say it again, you wouldt need to put rain water through a RO

Surely that has to be filtered it was black in that ibc

the water looked green...



anyway looked a  good way of doing it, i would probably try to link all gutters to one pipe, into one ibc, somehow link them all up?

Being that Im doing a little forward planning at the moment, as Ive ordered my WFP kit, I also went out and bought a couple of 200 litre water-butts today.

Its been drizzly rain this evening and one of the butts is out there connected up to a gutter collecting water. The TDS reading is 6ppm, I was really pleased with that.

yeh, that clear one needs cleaning out, the black ones nice and clean lol

What does concern me with storing rainwater and not purifying is that when i was a kid we had a water butt connected to the greenhouse gutter with a lid. I seem to remember lifting the lid and watching all the larvae swimming about in the water, even some worm like things in there too, so basically any kind of microscopic bug is likely to get washed into the tanks?

i noticed this too, it would be worth having the gutters run or drip over a filter funnel or some kind of cheap prefilter, to stop any of this-  but i would probably still put it through the ro too. I just would

How could the water be pressured up to run through an ro? I would too if i could work it out.

[Jon-scwindows]

youd need a booster pump.. i have a grunfoss one i got with an ro, but i have to use that with my system anyway.

Good site John,
but it doesnt take me an hour to wash my car so maybe the figures are inflated.
I wash all my wfp windows with rainwater.

I was thinking about this today as I running around picking a few pipe fittings up from the local DIY store about whether it would be feasible to loosely pack some DI resin into something, what sprang to mind was pair of my missus old stockings  but a sock would do, and then fit this into the downpipe that fed the water-butt or whatever container the water was held in. Not too tight, enough to allow the water to still flow through, but that would then be a home-made DI unit, save worrying about having to do it prior to use, save worrying about pumping it through (gravity would do that for you) and ready-made ready to use water for the windows.

Any takers?

interesting matt. one for jeff me thinks.

[Jon-scwindows]

with all the heavy rain weve had today and yesterday i bet i could have stored 5000-1000 litres just in 48-72 hours... pity i dont have it set up, so now i have to pay £100+ for the water bill...
shame i dont have any more ibcs! il have to dig holes in the garden and bury a few.

Seriously,.. you don't need to RO rainwater!!! 3/4 of it would end up going down the drain that way!!!!
Instead of spending on a booster pump, get a UV steriliser filter which will kill any living matter in the rainwater and simply put it through a DI vessel,... no waste, and water pretty much on demand.

[Jon-scwindows]

ok

I found this pic on another forum,.. but he reckons it works well and has actually reduced the amount of resin he uses. I think there is a flow restrictor in the inlet pipe otherwise the DI would take a bit of a hit when its raining hard! The water goes in at the bottom and the pure product water comes out the top.
