In my country it has been mandatory for at least a decade in any new construction or significant renovation to collect rain water and use it for at least flushing toilets.

It's not that expensive to install at that time and saves a lot of potable water. Seems like a no-brainer to me to do this everywhere.

In some parts of America, collecting rainwater is illegal.

Restrictions are mainly on commercial and especially agricultural use. It's not that bad for residential systems. https://www.worldwaterreserve.com/rainwater-harvesting/is-it... But in Georgia, you can only use the rainwater outdoors. So you can't legally flush your toilet with it.

Because, legally, you're stealing water from the basin and the basin's down stream users.

You're also not paying for the sewer use if you flush with it (since sewer isn't metered)

Some municipalities have ways to handle the second (as you have homes that are on well water but city sewer). Usually it's a flat fee based on occupancy or square footage.

This is mostly a myth, but check your local ordinances. OR do like the rest of us Freedudes do. Just do it.
