Build an rainwater collection system on your roof and connect it to your toilet - no more waste of drinking water An idea from Bart

It's been talked about earlier, and i am sure you are able to build it in much less than a month. You'll be saving water for years! An average person uses 34 liters of water per day for toilet flushing. That's more than 12000 liters annually.

I like it, would be nice to learn how to build this and to see how easy or difficult it is.

Clean water sure is good for us humans - some rain catching systems can even provide drinking water.
If its just for toilet flushing, the tricky bit is the system that fills the WC flushtank (pump?)

hi douglas, you make a reservoir, a big one, which is positioned higher than the flushtank. If the flushtank is empty it opens a faucet, which allows the water to flow in, and it stops automatically by a float. You can just connect the reservoir to the input of the flushtank and the water will flow in due to gravity.
You can filter it easily for the water to be clean enough for washing (it's better even than water from the tap, because rainwater contains hardly any calc.
And you can make a bigger cleaning installation to be able to use it for drinking purposes.
The difference between toilet and all the other purposes is that you need pressure for the other purposes. It'll cost more money.

@maarten i would like to know as well. And i think it can be done easily, thus making it interesting for your followers to do it as well. You might even start an action to collectively buy stuff and save money.

Sounds nice!!

I agree with bart, this can be done in much less than a month, so maybe maarten could present the idea to his neighbours, offer free or cheap instalations to people nearby, create a Do-it-yourself tutorial and spread it over the internet... Anyway, This is a Great Idea!!

Wow this is a great idea, especially since Holland is so rainy!

@enru: especially this month would be a great month to have this system. Makes me think: don't forget a overflow drain (if the tank is full, the water goes into the normal roof drain.

Yes, this month I think you can collect enough water for the entire year... :-)
