Oh ya doesn’t has to use bleach:
Methyl Ethyl Ketone
Carbon Tetrachloride
Oh, yes! Chlorinated hydrocarbons in the sewer! Heh. Actually adding a massive volume of bleach to the sewer system is a very bad idea; bleach reacts with the urea in urine to produce chlorine gas (possibly by way of chloramine-T)- which would then come out of every sewer vent in the city. Actually, it might be a way of cleaning up a lot of vermin....
