Yes, even the stuff that gets flushed! It is thoroughly purified and cleaned and sterilised before being cycled back to the drinking water reservoirs.<br/><br/>Part of that process is passing it through the hydroponics tanks where all the nutrients are taken out and used to help grow plants, and thus produce food and oxygen...<br/><br/>The soaps available on Mars are all biodegradable, by the way, and thus will also be useful in growing the plants.
