I collect my rainwater for my gardens. The plants know the difference. Especially new plantings and transplants. I used to collect all my gray water too. That was from sinks and laundry. I had a neighbor rat me out to code enforcement and that was the end of that. My excess rain water after the covered barrels hit the full spill-off runs into my swimming pool.

Tomatoes offer a yield at least 50% better when using rain water to irrigate over chlorinated municipal water. So too do grapes, kiwis, peppers, asparagus, lettuce, and brussell sprouts. Peach and plum trees prefer rain water also. The trick is being handy and discrete enough to artfully plumb it where it needs to go while going un-noticed. I do have regular high pressure buried irrigation for the lawns with back-flow preventers and that makes the code enforcement people happy.

Nosy neighbors or talkative family members are your biggest hazard.

I’ve also plumbed the condensate from my full-house A/C to plants that need it during Florida’s dry season. :)
