Orillia Wastewater System Master Plan

The City of Orillia has retained the services of the Ainley Group to undertake a Sanitary System Master Plan with the objectives of developing a comprehensive, long-term sanitary servicing strategy for existing and future land use within the city limits of Orillia. The process will involve an assessment of the existing servicing infrastructure to identify necessary upgrades and future servicing priorities.

This study is being completed in accordance with the Master Plan process as identified in the Municipal Class Environmental Assessment (Class EA) document (amended 2015). It will follow Approach #2 with the intent to fulfill the Class EA requirements for the Schedule A, A+ and select schedule B projects identified within the Master Plan as well as to provide the basis for future Schedule C projects.

The Project:

The Orillia Wastewater System must continue to meet the needs of the community in the most economical and sustainable manner, in full compliance with regulations, and with minimal impact on the natural environment. As such, the existing systems will be reviewed to identify and define their condition, compliance and performance-related issues that might affect the ability of the systems to meet future needs. As a result, this master servicing study will address:

• Review and update of the City’s existing Engineering Design Standards for wastewater systems.
• Review of existing and future development and project future wastewater flows.
• Visual condition assessment of existing pumping stations, WWTP, and septage receiving station.
• Update the City’s existing sewer model and identify existing and future system bottlenecks.
• Develop a prioritized replacement / rehabilitation plan for the existing system to address capacity issues, reduce Inflow / Infiltration, and repair deteriorated system components based on a risk-analysis approach.
