The question was whether it was legal to do Rainwater Capture Systems in Fairfax.
To be honest, I was not certain about this, so I reached out to our local building department. They were able to confirm that this kind of installation is acceptable.
Of course, thinking about installing a Rainwater Capture System now is a bit of wishful thinking for a few months, but it would be worth doing for next year.
Maybe more intriguing is the idea of graywater systems in general. I should note that I am an electrical engineer, not an expert in water systems. I am considering putting in a graywater system to catch shower water and use it for irrigation.
My research to date is that you can do a graywater system using clothes washer rinse water without any permits at all. You can also put in a "Simple" graywater system, which is sized for one- or two-person home. This requires a permit for construction, and it requires you to notify the County Health Department.
You can find the requirements summarized HERE.
So, thank you for the question, thank you for caring.
