The proper collection and treatment of wastewater has a direct impact on the health of London residents, our environment, and the ability of the City to grow and prosper.
Operating a wastewater treatment system often requires the upgrade of old facilities and the construction of new ones. By developing an informed plan for the next fifty years of wastewater treatment in London, the City will ensure that the improvements we make today will contribute to our long term goals, while planning ahead allows us to save money now to responsibly pay for future projects.
This study will look at the need for new and upgraded facilities as part of our commitment to environmental protection, growth servicing, and asset management. The City is seeking input as to the best ways to accomplish these goals.
The City of London currently operates five wastewater treatment plants and 38 pumping stations. The wastewater treatment plants are located along the Thames River.
The Wastewater Treatment Plants use:
- Screens and settling tanks to remove solids;
- Bacteria to consume organic material and convert ammonia to nitrates;
- Chemicals to remove phosphorous; and,
- Ultra-violet light to disinfect.
Material that does not pass through screens is removed and hauled to the landfill. In secondary treatment, bacteria are grown to break down organic material in the aeration section.
Annual Wastewater Treatment Plant Reports for 2018
The Southland Plant was shut down in March 2018 and now is a pumping station with flows directed to the Greenway Wastewater Treatment Plant.
