Rainwater harvesting

[Dan Paton]

I'm only looking for rough answers here guys but with a night of quite heavy rain. How much water roughly can you collect from one side of a roof ( 2 bed house) I'm just not sure wether it's worth setting it up or not . Cheers

Hey Dan. Try the search bar at the top of the page as last year there were some quite in depth posts on the topic.

It's surprising how much you can collect

I have been thinking about doing this myself. Cannot decide if it is really worth it yet mind.

If you want to go down that route, you would need a big tank holding 5k litres , you would get a lot of water off a roof , but you would have to hold a lot for when it didn't rain for a while if you are using say "350 litre s a day ."

Def worth it ! Get a cheap ibc used but fairly clean , mine used to contain some kind glue , easy clean . Get some cheap piping and a ladys nylon at the end . Guessing you could do it for 50-70 pounds . Collecting at least 1000-1500 ltr. A month , sometimes more ,From the one side of half a roof. Got pics if you search the topic

I'm interested in this, but am wondering do you guys tap in too the down pipe or have a separate outlet on the gutter run.

If I was put an extra outlet on the gutter run, and run this down to an I.B.C what happens when the tank is full.

Do you guys have to drill an over flow in the top of the tank or just let it fill, letting the gutter carry on as normal once filling is complete ?

 

[David K]

I've diverted the downpipe to the tank . When it's full I'll just let it run over .

 

[The window cleaning kid]

thanks that's just gave me an Idea.

And can you recommend a pump to run from the I.B.C. then Through Di and on to vans holding tank please.

 

[Posh]

I use a normal backpack pump. Hose in butt. Pumped out to Di & into whatever you want.

Nothing fancy needed

Thanks David. I will do a search and see if I can find your pics.

I need to set aside a weekend to do some reasearch on the subject, but certainly like the idea of it.

I Got my DI onboard just before the reel , so that's just a matter of getting it pumped to van . A sub pump will do .

[David K]

Just an update, got 800 ltr. The past 24 hours ... /emoticons/tongue.png Free of charge ! And no toll on my RO.

ok I'm going to do this, I'm an end house with 3 roof sides.

Got to be cheaper than my baby R/o right.

sure ! :thumbsup: Your only cost would be some DI use. But it's nothing. My ppm from roof is 00.9 , but you gotta keep those gutters clean , and check out the ppm at your current state. Anything under 20 is great . Then just regularly clean the flex hoses ( what I use ) and flush the lady's nylon or whatever you use at the end just before the tank ( IBC)
