Wastewater treatment processes

Wastewater treatment is a process that removes contaminants from wastewater or sewage and converts it into an effluent that can be returned to the water cycle with minimum impact on the environment.

Peel has some of the largest and smallest treatment plants in the country.

Inglewood Wastewater Treatment Plant is an extremely small plant in comparison to its two sister plants on Lake Ontario. Inglewood receives roughly 0.02% of Peel's total flow. Clarkson and G.E. Booth receive over 5000 times more sewage than their smaller sister plant.

Clarkson and G.E. Booth treat wastewater through conventional liquids treatment and biosolids management.

Inglewood treats wastewater through a comminutor (a machine that cuts up solids in raw sewage in preparation for purifying treatment), screens and biological treatment tanks.
