Very preventable, intentional dumping of raw sewage in this day and age should be banned, make retention ponds like the Oil industry has to hold the raw sewage until the plant is back into operation and then treat before release.
I'm guessing that seeing how there will be no more transfer payments with any substance, we can expect to see Montreal and Quebec City dumping untreated sewage into the waterways on a regular basis
(no pun intended)
