My Tank Thread
I learned something working in the dairy industry its technically illegal to put milk into the sewage system. Its unlikely someone would be charged for putting chemicals out in their gray water but it can happen. The company I worked for S*puto got fined for "releasing a hazardous substance" that substance was milk.
I worked summer jobs at Kodak years ago.
For some processes, they removed water from the nearby river, but could not put it back in the same condition it came out because it already exceeded certain water quality standards (don't recall which ones) while in the river. They ended up not using it because it was more expensive than using tap water instead. Common sense does not always prevail in situations like that.
