And  the Sewerage System is a Chemical Factory designed to process certain
chemicals and solid objects. Not Engine Sump Oil, Spent PCB Etchant and
other chemicals that get disposed of down this convenient system.

True, but it's one of the chemicals that a Sewerage System is designed to
process. All Sewerage Systems rely on the presence of  Dihydrogen Monoxide
for their operation and it will continue to be used for the foreseeable
future despite the fact that thousands of people are killed every year by
this chemical. As a Sewerage Engineer I know  put it " On average, there are
more people killed in the UK every year getting out of bed, than are killed
by us putting Dihydrogen Monoxide into the environment. Of course some years
things go wrong and there is a cluster of deaths, but what the hell, we
contribute to the economic heath of this nation so no politician is going to
ban us from using this chemical."
