I don't think what I am proposing would prevent water from hitting the storm drains. For example, my neighbors, the ones blasting water onto their laws, they would use recycled water instead of clean drinking water. This problem is complicated because homes are not designed with extra space for what in commercial buildings is called "mechanicals". A room or more where building systems are housed and maintained. If I were to ever build my own home I would likely design a room, about the size of a two car garage, to house such systems. Anything from water recycling to batteries, heating, cooling, network, etc. I would probably make it an extension of the traditional two car garage just so that it is conveniently located with access to both tools and easy entry/exit of large items when you have to repair or replace something. Pretty much every home in my neighborhood could easily have this. They simply were not thinking this way.
