East London Sanitary Servicing Study


NOTICE OF STUDY COMPLETION

The City of London (the City) is planning for future growth and development expected on the east side of the City, within the Vauxhall and Pottersburg wastewater treatment plants (WWTPs) sewersheds.  To shape this strategy, the City conducted a study to identify the preferred approach for managing future wastewater flows collected within these two sewersheds.  Following the Municipal Class Environmental Assessment process for a Master plan, the study identified recommendations that reflect the current and future needs of the Vauxhall and Pottersburg sewersheds through a collaborative public and stakeholder consultation process.

The expected population growth in the sewersheds, their current capacity, and the condition of the Vauxhall and Pottersburg WWTPs were assessed in order to identify the recommended alternatives. Section 8.0 of the Project file outlines a variety of future work (e.g., supporting studies and investigations) to be completed in order to support the implementation of recommended solutions identified as a result of the study.

Regarding the preferred treatment system alternatives, the study found that Alternative 3 (Major capacity Increase at Vauxhall WWTP) was identified as the only feasible short-term alternative, and Alternative 5 and Alternative 6 were tied for the preferred long-term alternative. Both recommended replacing Pottersburg and Vauxhall WWTPs with a single new WWTP.

Regarding the preferred collection system alternatives, the study found that Alternative 2 (Inspect Sanitary Sewers for Cracks) and Alternative 4 (Evaluate Available Capacity of Trunks in the Pottersburg Sewershed) were the two short-term solutions that scored favourably. The study determined that Alternative 2 (Conduct Study to Identify Collection System Efficiencies) and Alternative 3 (Replace Existing Vauxhall and Pottersburg WWTP with Pumping Stations) were the two long-term preferred WWTP alternatives, dependent on the location of the proposed new WWTP.

Subject to comments received as a result of this notice, the City of London intends to officially adopt the recommendations documented in the Environmental Assessment Project.
