Sanitary Master Plan Complete

About the plan

The Waterloo Sanitary Master Plan outlines a comprehensive strategy for updating and improving the City of Waterloo’s sanitary sewer system to support population and employment growth through 2051. The plan identifies current issues, evaluates future needs, and proposes solutions to improve system efficiency. Key goals include reducing leaks and infiltration, repairing aging infrastructure, and planning upgrades in stages to manage costs effectively. The plan also addresses environmental protection and climate change resilience. By following this plan, Waterloo can ensure its sewer system remains reliable and sustainable for the future.

How we incorporated your feedback

The public's contributions were carefully reviewed and integrated into the Sanitary Master Plan. Through the Online Public Consultation Centres (PCCs), residents were invited to review study materials and provide feedback. During the second PCC, one specific comment was received, which influenced the evaluation criteria and ensured public concerns were addressed.

For example, input from residents regarding the need for system reliability during extreme weather events informed the prioritization of mitigation strategies for inflow and infiltration. This feedback was reflected in the plan’s focus on reducing basement flooding risks and enhancing the system’s resilience against climate change impacts. Additionally, the open consultation process underscored the importance of maintaining a transparent planning approach to align with community expectations.
