Phosphorus Reduction Strategy
The City is undertaking a project to retrofit a portion of the Wastewater Treatment Facility (WwTF) in order to meet new Provincial regulations.
As of January 2018, the project is in the pre-design phase, which includes site layout planning, confirmation of the technology path forward, life cycle costs, investigations, assessments, equipment preselection, costing, schedule, value engineering, etc.
The City of Barrie is continuing to be in compliance with the Environmental Compliance Approval and is committed to continuing its efforts to protect Lake Simcoe and Kempenfelt Bay. The Lake Simcoe Phosphorous Reduction Strategy is designed to achieve proportional reductions from each major contributing source. As such, due to these provincial regulatory changes, the Barrie Wastewater Treatment Facility (WwTF) is required to meet extremely low total phosphorous effluent quality limits of 0.1 mg/L, prior to discharge into Lake Simcoe. Currently, this is the most stringent effluent quality limit in Ontario.
To meet this new effluent regulatory limit, the City of Barrie needs to provide its Operations Group with the tools that are needed to continue their success, while being cognizant of the costs of the project. To this end, the City of Barrie is undertaking a project to retrofit a portion of the Barrie WwTF. The City is currently undertaking the Pre-design phase of the project, including site layout planning, confirmation of the technology path forward, life cycle costs, investigations, assessments, equipment preselection, costing, schedule, value engineering, etc.
Based on the preliminary work, it is envisioned that the City will be moving forward with the innovative Membrane Bioreactor Technology (MBR) type of technology. This type of technology can be provided, for example, in hollow fibre (like spaghetti noodles) or flat plate layers (like lasagna noodles).
The membrane technology is placed in large tanks that hold pretreated and screened wastewater. Pumps then create a vacuum within the hollow fibres/plates which pull the liquid through the numerous tiny penetrations. This action separates the wastewater components into solids and liquids. Each component is then treated using standard processes.
“The phosphorus reduction strategy is a key part of the Lake Simcoe Protection Plan. Phosphorus helps plants in the lake grow, but having too much of it leads to excessive plant growth and a depletion of oxygen levels the fish need to thrive. The strategy to reduce phosphorus levels in Lake Simcoe by almost 40% will help improve water quality and protect the coldwater fish community” Source: Phosphorus Reduction Strategy
Quarterly updates will be provided, starting at the end of March 2018.
A Public Open House will be held in 2018 (date to be determined).
No utility service interruptions are anticipated by the project.
There will be no traffic impacts during the design phase. There will be increased truck traffic and contractors vehicles entering and exiting the WwTF during the construction phase anticipated in 2020
Anticipated dates for main phases of the projects:
Issue public procurement documents for the Pre-selection of Membrane Vendor (in part to assist in the Preliminary Design)
Complete Preliminary Design
Public Information Centre
Detail Design and Tendering
Award Construction contract
Complete Construction Phase
