“New building flat roof apt. construction should be built so to pipe rainwater from the roof to a filtered basement storage tank to be piped over to the laundry room.“
Incredibly, this may be illegal in many areas. That water belongs to the government.
That tank better filter it. Rainwater is not clean water.
I was aware of that, and I collect it in the summer for the garden, which simply means it ends up in the ground there versus the bare ground on the back. But legality it depends where you live:
The city of Tucson, Ariz., which receives a meager 12 inches of rainfall in an average year (much of it coming in big downpours), decreed not only that collecting the rain is legal, but that all new commercial development starting in June 2010 must include a rainwater collection system.

But I also wonder how restrictions that deals with the issue of air rights above your house?
