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 and expansion of existing facilities and the construction of new infrastructure. By developing an informed long term plan, the City will ensure that the wastewater infrastructure improvements we make today will effectively contribute to our long term goals.

This Master Plan will consider 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 first Wastewater Treatment Operations Master Plan virtual Public Information Meeting was held on April 22, 2021. You can download the presentation or watch a video of the virtual meeting.
