All the regulations around the pumping of raw sewage from a ship up in the river and Montreal has been given the go ahead to dump 8 BILLION liters of raw sewage into the St Lawrence over a week
Major construction work to lower the Bonaventure Expressway to street-level in downtown Montreal requires moving a snow dump, which is connected to a big sewer. This sewer's pipe measures five metres in diameter and normally carries sewage to the city's water treatment plant. However, in order to carry out the work to move the snow dump, the sewer's pipe must be drained.
There's also another reason that the interceptor sewer must be drained: the city must remove old, wooden building hoops that have started to detach from the structure. The pieces breaking loose could jeopardize water treatment.
The eight billion litres of wastewater would flow directly into the Saint Lawrence River via 26 interceptors, which correspond to areas used for sewer overflow during heavy rains.
Some observers had noticed a discoloration in the water but Richard Fontaine, the head of city's waste water management, said colour is not a clear indicator of the water's quality.
