Why would it be sewage? It is gray water not black water. If you wash
your
car is the water runoff "sewage"?

So, you think it would be ok to run your tub water, kitchen sink water,
dishwater water, lav water, and all other water from your home except toilet
water outside onto the lawn?

For your question regarding sewage on a car. I guess if you **** in it and
then rinse the **** onto the sidewalk, there would be issues.
