东污水干渠修复工程

Growth within upstream areas continued to increase flows to the east trunk and ultimately the G.E. Booth Wastewater Treatment Plant in Mississauga, Ontario. 的 rehabilitation of this trunk and operation as a storage facility will provide flexibility and additional system resiliency and was thus considered a critical project for the Region of Peel.

的 project included a condition assessment of the upstream Energy Dissipation Chamber (EDC) and the abandoned section of the East Trunk, 使用闭路电视完成, 360摄像头和Faro 3D扫描. 的 data from the condition assessment provided the basis of the feasibility for rehabilitation or decommissioning.

的 可行性研究 was completed to determine the approach of achieving in-line storage for the Region. 它评估了四种选择，包括:

1. Replacement of the abandoned EDC with rehabilitation of the trunk sewer
2. 新型存储系统
3. 修复东区污水渠及污水干渠
4. 的 complete decommissioning of the abandoned EDC and trunk sewer

的 可行性研究 was supported by the completion of the condition assessment, 康复方案评估, 液压评估, 边坡稳定性评价, 以及许可和批准评估.

的 conceptual design evolved from the evaluation of options identified in the 可行性研究. 的 conceptual design included the evaluation of two storage systems, using tanks for storage and parallel pipes for storage with various operational options. 概念图的特点是四个平行的3,600mm storage pipes with flushing gates and a vortex drop structure, and two concrete tanks with water spray nozzles for cleaning/flushing and a vortex drop. 的 final recommendation to the Region of Peel was to construct the parallel pipe option.
