Rainwater Harvesting QA - Cost, is it Illegal, how I treat, etc,.

Today I’m answering Rainwater Harvesting questions about my rainwater collection system tour video.

NOTE: forgot to talk about two other questions... annual rainfall in this area is about 12" and the water in the pipes transfers to the tan tank via a level difference. It is explained in the first video. Here is the link:) https://www.youtube.com/watch?v=pNXooT2FVXM&t=435s
