Wastewater Assets

The City's Wastewater assets are critical for ensuring the efficient and safe collection, and treatment of wastewater. This includes the maintenance, upgrading, and management of infrastructure such as sewer lines, treatment plants, and pumping stations. The Asset Management Plan focuses on sustainability, cost-effectiveness, and regulatory compliance, ensuring that the wastewater system meets the current and future needs of the community.

Linear wastewater infrastructure includes: 

  • Wastewater Collection: Sewer Mains, Sewer Laterals, Maintenance Holes

Vertical wastewater infrastructure includes:

  • Wastewater Collection: Pumping Stations
  • Wastewater Treatment: Wastewater Treatment Facility
  • Biosolids Storage: Biosolids Storage Facility

Overall, the wastewater asset replacement value is approximately $3.0B and wastewater assets are in good condition. 

Asset Management Plan Key Findings

Full information about the City's management of wastewater assets is contained on pages 137–152 of the 2025 Corporate Asset Management Plan.

The 2025 Corporate Asset Management Plan includes three key findings:

  • Sanitary sewers are generally in good condition with 90.3% in fair or better condition. The City’s sewer rehabilitation and maintenance programs support reliable service delivery and reduce sewer backups as well as costly infiltration of stormwater.
  • There is an investment gap associated with the renewal of vertical assets. Condition assessments have been completed for a number of facilities and a capital renewal program is being developed to close this gap. The City must continue to evaluate and prioritize the remaining renewal needs.
  • The City is upgrading and expanding the Wastewater Treatment Facility to meet Provincial regulations for phosphorus reduction, accommodate population growth, and improve aging components.
