Rainwater Harvesting - will this work?



Recommended Posts

Rachel

I 'm glad I found this topic. I got caught in an almighty downpour on the way home tonight and stuck a bowl outside when I got home. Measured it and got 12ppm. That for me is unreal. My cold water kitchen tap is anything from 250ppm  (today) to 280 ish.

I'm on a meter too. If anyone is in the southeast (London /Surrey /Kent etc.) and is using rain water, could they give me an idea of how they are harvesting it and roughly how much they get. It would really be appreciated :-)  I'm guessing I would still have to supplement it to a degree but any water I can get almost free is def. a bonus !

I have 205 ltr  barrels connected to my down pipes from spouting.A couple of neighbours allow me to do it as well.I just use a 12v battery and connect a suction pump to it and pump the water up to a 1000ltr cube in my back garden.Its about 34 ppm but my tap water is 340.You would be surprised how much you can collect.I do clean their windows for free as a sweetner.

I got 2 sheds

put a bit of guttering on each 

don’t have to be brilliant long as it runs down 

l got the downpipe & wrapped a pair of tights round it to act as a filter

i then put the downpipe into a funnel which fits in the little side hole of the lid of the water butt perfectly 

believe me your be surprised how much you collect.

i run the water into my backpack which then pumps it through 2 4.5 litre di’s into my holding tank.

as the chap said above if you got no backpack you can just use a battery & pump. Connect a bit of hose onto the pump long enough to fit into the bottom of the water butt & a bit of hose long enough to reach your tank or Jerry can & connect it to the battery

If no rain and run out of rainwater I pump the mains through an ro system until I have enough rainwater again
