Hello everyone,
we are currently in the planning phase of our new build.
We also want to include a cistern to use rainwater for garden irrigation.
Now we're wondering if the rainwater can also be used for other purposes,
for example, toilet flushing or laundry.
The water collected from the roof will be filtered through several screens to keep it clean.
Our question is whether this makes sense or if there are any experiences with this.
Of course, we hope to save costs over the years on rainwater disposal, water supply, and so on.
The cistern will have a capacity of about 15,000 liters (3,960 gallons).
We would appreciate your experiences or opinions.
Best regards, Andreas94

No, we don’t have a fresh water supply line for the toilets and urinals. That’s exactly what I’m saying. There are no pipes carrying both types of water.
Yes, go ahead and hammer. I just want to say one more smart or foolish thing...
No pipe may carry both types of water—that was your statement! However, rainwater from the cistern may indeed be mixed with fresh water. Just not the other way around. That was my point.
Let’s leave it at that now. I was only joking. Don’t take it the wrong way. We both know what the right approach is.

Andreas9430 Apr 2020 12:54It makes sense that both types of water should not be mixed during operation.
As I see it, there are two possible options here:
1.
Run a separate pipe to each water outlet and connect them directly to the cistern.
If the cistern is empty, it would need to be refilled.
2.
Is there a separator, as mentioned earlier, that regulates between the two outlets, so that only one pipe is needed?
Or would two pipes still be required in this case?
