Here in the Los Angeles area we have one of the best water redirection systems in the world. And as you have stated, it will all flow into the ocean. I can see some reason behind the comments about chemicals and such, but after the first day, good heavens, catch the clean water.
It boggles the mind how much we carp about water, we blow on L. A. River restoration, and avoid spending on collection.
I’ll bet we have millions if not tens of millions of acre feet of water flowing into the ocean daily right now.
Up in Oregon they tried and failed to tax the run off rain water, we live in the coastal foot hills it’s gotta run somewhere.
Now they are trying to tax the run off rain water per homeowner in Salem, Oregon.
I have looked at and even had quotes in putting in a rain run off system but the cost was hyper inflated.
As I understand it the systems that are used now are not meant to come into the home for toilet flushing/washing ect..
I surely don’t need rain water to water the property.
