Do you wash your scrubs together with your other laundry or do you wash it separately?

I live alone and don't like to waste water so my washes are typically separated into 3 piles: 1) light colors of normal fabrics and clothes, 2) dark colors of fabrics and clothes (and anything that might bleed coloring or has stains that might bleed into the wash), and 3) the heavy fabrics like my scrubs, hoodies, dish towels, and socks all go into a wash together (there all dirtier than everything else in their own way so I figure it's better to wash them together and keep the rest of my clothes separate from them).

yup
