Using our gray water now............

we put two lines out, one is the shower water, one is the washing machine. The shower water is making the grass really grow. the washing machine line is new, so I do not see a difference there yet.

I want to dump the shower water directly into the garden and want to know the pros and cons of this. we use phosphate free soaps. We have very well drained soil, being in the foothills.


Thank you.
