How do shampoos and soaps effect the water that goes down the drain?



  1. 0 Votes

    The effects on water quality of soap and shampoo products that are drained through household plumbing would be minimal.  This is because water that is drained through household fixtures (such as the shower drain) enters the sewage system and is treated just like sewage is at a treatment plant.  The various treatment techniques will usually remove any type of chemical compounds or particulates found in cosmetic products, making the water potable and usable again.
