Hey folks. It has been a while since I have posted anything. I hope you all are doing well in this new year.

I will hopefully start building my new home in the spring time. So now I am thinking of what types of things I want for it. I am thinking that I would like to have all of my washing machines, dishwashers, drains for water heaters, HVAC, etc. all go into one drain line. I don't want to have all of these going into my septic system.

Have any of you done this? Are there any websites that can show me what and how to do it? Is there anything that I am missing? I mean it sounds like a good idea to me, but I'd like to poll folks that have been through it.

Also, what do you think of the idea of containing the rain water from the roof. I was thinking I could use it for watering flowers or many other things.

Thanks for your help.
