Green and blue title saying Biosolids Strategy


The Region is embarking on a multi-year process to develop a new Biosolids Strategy and we need everyone to be involved to help identify the best possible solutions.

We are all involved in creating biosolids, so we should all be involved in determining what we do with them as a community. The best strategies take the whole community's interests to heart and we need the public to help us identify the best possible solutions.

What's New

Join us at one of our upcoming Public Consultation Centres.

With your input along the way, the Biosolids Strategy is nearing completion. Join us for our final round of Public Consultation Centres.

What Are Biosolids?

Biosolids are the processed organic material that remains after the treatment of our wastewater. Any time water goes down the drain from your homes and into the municipal sanitary sewer system, it carries organic material that has to be removed at the treatment plant. This may include materials flushed down the toilet, soaps, detergents, food, etc. Once treated, this material is turned into a product called biosolids.

Residents and businesses in Region of Waterloo communities generate wastewater every day, 365 days a year. This is not going to change and in fact with a growing population the amount of wastewater will likely increase in the future. It is the Region's mandate and responsibility to protect public health and the environment by treating and managing this wastewater and biosolids.

Current management practice involves spreading biosolids on agricultural land as a fertilizer. When this is not possible due to weather, it is disposed of in landfills. With our community growing, the Region is always considering our future plan for biosolids management.


We Need a Sustainable Solution

We need a sustainable plan for the community's future. The Region is embarking on a muti-year process to develop a Biosolids Strategy. This Biosolids Strategy will take a critical look at today's practices, consider all the available technologies and develop a sustainable way to manage biosolids within the Region over the long term.

In June 2015, Regional Council approved a recommendation to update the previous Biosolids Master Plan by developing a Biosolids Strategy. The Biosolids Strategy is expected to be completed by 2018. The Biosolids Strategy will result in an update to the Region's Biosolids Master Plan prepared in 2011.


We Need Your Help

Since we all contribute to the production of biosolids, we should all be involved in determining what we do with them as a community.

The best strategies take the whole community's interests to heart and we need the public to help us identify the best possible solutions. As such, public participation will be a key part of the strategy as demonstrated through the engagement approach approved by Council (see in the historical information listing below). The Region will be communicating with and engaging all stakeholders throughout the Biosolids Strategy development and an engagement plan is being prepared so the community can understand how their participation fits into the process.

Thank you for your feedback

On November 17, 2015, we held a popular launch event for the Biosolids Strategy. Over 100 attendees came to hear CBC science journalist Bob McDonald speak about the importance of getting involved in the process to develop plans for the community. 

To launch the Biosolids Strategy project, we held the event to generate awareness and interest. We hope that has sparked your interest to keep participating in the project. 

Attendees were asked to complete a survey to give us their feedback on some key questions about planning for our biosolids future. That survey closed on February 5, 2016. We thank all those who provided feedback. It will help guide our next steps.
