Engagement opportunities


Virtual Public Information Centres (PICS):

The City will be hosting three virtual Public Information Centres (PICs) for this project, with the final PIC posted online on May 26, 2025.

A Public Information Centre (PIC) is a meeting or event where people can learn about a project and share their thoughts. It’s a way for the public to ask questions, give feedback, and stay informed. PICs are used during Environmental Assessment (EA) studies to help project teams and the community exchange ideas and information.

These PICs have shared information about our current approach, the evaluation of the various components of the biosolids management strategy, as well as a preliminary preferred solution and location(s) to solicit feedback.

Once feedback is received, considerations regarding project implementation, environmental protection measures and other considerations, as well as next steps will be presented. A final Master Plan Report will also be made available for public review and comment upon completion of the Master Plan, however the public is encouraged to reach out with comments, questions or other feedback to the project team at any time.


This PIC will be user directed, allowing attendees to proceed through the material in the virtual environment at their preferred pace. The PIC will be available until July 4, 2025, and will include a questionnaire as well as various other methods to contact the project team with additional input.


In-person drop-in meeting:

An in-person question and answer session with City staff will also be held on June 17 at at Earl Nichols Hall (799 Homeview Avenue, London) from 6:00 to 8:00 pm.

The format will be a drop-in centre. Any member of the public who wishes to attend this Q&A session can stop in at any time during the 2 hours.



About this project

The City of London is updating its Biosolids Management Master Plan to make sure our biosolids are managed in a way that is environmentally responsible, cost-effective, and ready to support a growing population.

This plan follows the Municipal Class Environmental Assessment (EA) process, which includes input from the public, local First Nations communities, agencies, and other parties. Since all areas of London are connected to wastewater treatment plants that produce biosolids, this project will impact the entire city.


What is the purpose of the plan?

The main goal of the Master Plan is to create a reliable and long-term strategy for how we treat and manage biosolids. It will cover short-term needs (within 5 years), medium-term plans (within 15 years), and long-term solutions (over the next 30 years). Some improvements may be easy to put in place right away, while others will take more time and planning.

The plan will look at different treatment options, how the biosolids might be used or disposed of, and where new facilities could be built. All options will be carefully reviewed based on their environmental impact, cost, community benefits, and how realistic they are to build. The plan will also align with the City’s climate goals, including the commitment to reduce greenhouse gas emissions.

    The City of London operates five wastewater treatment plants throughout the City. As part of the treatment process, solid material is separated from the liquid. Solids are also generated as by-product of the biological and chemical processes used to treat our water to ensure it meets all required environmental and health standards. Solids generated at our Adelaide, Oxford, Pottersburg and Vauxhall wastewater treatment plants are thickened (mass reduced by approximately 70% due to water removal to minimize transportation) prior to transportation to the Greenway WWTP, the City’s largest facility which treats 60% of the City’s wastewater. Solids transported to Greenway from the other four plants are dewatered (Water content reduced to <10%) prior to being incinerated. The by-product of incineration is ash, which is then transported to the City’s W12A landfill. It is anticipated that the current incinerator can be repaired/rebuilt once more prior to reaching the end of it’s asset life sometime in the next 15 years.
