Rainwater harvesting - storage


Recommended Posts

I was considering harvesting rainwater, mainly because we are on a metre and the bills gone up again. So I was wondering from you guys who do this, how much storage do you need to keep going.


I don't intend to use all harvested water but if I could offset the mains usage it would be good. Any assistance greatly appreciated.

I can put one IBC at the front and another at the rear of my property. I can put one at my Mother's property. So thats 3000 litres.

On average I use 300 litres a day. (judging by whats left in the van tank) so that's about two weeks use. During the autumn/winter period we are likely to have rain during a two week period. Like I say I'm not expecting to use only rainwater, but to cut back the use of mains water, and of course the occasional tank top up at customer properties.


Any thoughts?

Yeah definitely worth doing if you have the space for tanks. Might want to check if it safe but I think you can stack the metal frame ones. Also think about filtering any larger sediment out before the rainwater gets to the IBCs.

I plumbed rain water into the toilets in our last place. Why flush away 7l of good water every time you take a piss?


Tried using it for drinking water many years ago. Not great unless boiled.
