Ingersoll Wastewater Treatment Plant recognized as Project of the Year by Ontario Public Works Association

Multi-year construction project recognized for historical restoration and preservation of existing buildings, structures and facilities

The Ontario Public Works Association (OPWA) recently recognized improvements to Ingersoll’s Wastewater Treatment Plant (WWTP) with a Project of the Year designation at an awards ceremony in Mississauga on January 24, 2019.

The multi-year construction project, which began in 2013, saw upgrades to some existing areas of the plant and full demolition and replacement of others. The project was recognized in the Historical Restoration and Preservation category for efforts to preserve the existing 1974 plant infrastructure while reducing the footprint and impact on the environment.

Phase I of the project served to increase the wastewater treatment capacity to an average day flow (ADF) of 12,945 m³/day. Further Phase II upgrades will be completed in the coming years to accommodate a projected ADF of 14,250 m³/day by 2035 to service ongoing growth in the community.

Implementation of energy efficient design, including dissolved oxygen control systems, energy efficient mechanical systems, and premium efficiency electrical motors, along with energy smart automation controls will minimize long term energy consumption and greenhouse gas emissions. In addition, captured biogas will be used to offset the use of non-renewable natural gas as part of the cogeneration fuel system, which powers the plant’s boiler heating system.

The project required technical expertise and a complex phasing strategy, as the older WWTP infrastructure needed to remain functional until the new plant components were operational so as to not disrupt wastewater treatment operations.

The Ingersoll Wastewater Treatment Plant provides wastewater treatment for residential, commercial and industrial use in Ingersoll and is designated as a Class III Wastewater Treatment facility. A high level of treatment is achieved before the treated wastewater effluent is discharged back to the environment at the Thames River in full compliance with provincial regulations. Biosolids that are generated at the Ingersoll WWTP are treated and stored offsite before being applied to agricultural land as a valuable fertilizer product.
