Filtering
Raw sewage contains organic matter that serves as a food source for bacteria. As bacteria consume the organic matter, they use up oxygen during the decomposition process. This results in a decrease in dissolved oxygen levels in the water where the raw sewage is discharged.
The name solid raw sewage is called a sludge

heavier rainstorms will frequently overwhelm portions of the region's sewage system and accelerate the spill of raw sewage into Burrard Inlet and the Strait of Georgia.
Raw sewage contains organic matter that can be broken down by bacteria, using up oxygen in the water during the decomposition process. This can lead to a decrease in oxygen levels in the water, potentially causing harm to aquatic life and disrupting the ecosystem.
The solution to sewage problems is to install a more efficient system that can handle larger volumes of raw material. Improving the efficiency of the system so that it can process higher volumes of waste.
Raw sewage refers to untreated wastewater containing a variety of contaminants, including human waste, chemicals, and organic matter. Sludge, on the other hand, is a semi-solid residue produced during the treatment of sewage. Sludge has had some treatment processes applied to remove solids and pathogens from the raw sewage.
The density of raw sewage can vary widely depending on its composition and the presence of solids. On average, it can range from 1,010 to 1,050 kilograms per cubic meter.
