Condition Assessment of the Region’s Storm Sewer Infrastructure

completed

Detailed condition assessment of the Region of Peel’s storm sewer infrastructure to determine its condition and to identify short-term and long-term remedial actions necessary to maintain the storm sewer infrastructure. Permanent Pool Volume provided in SWM Facility is 7823m3 (regional storm) In 2008, The Region of Peel constructed a storm water Management Facility at Mayfield Road and Heart Lake Road to service a tributary area of 22.3 ha, being comprised of 8.7 ha of arterial road drainage and 13.6 ha lands additional area which drains to the arterial road right of way. This facility provides storm water Quality Control (Enhanced Level i.e. 80% Total Suspended Solids removal) and Erosion Control and maintain Water Quantity flows below existing flow rates up to an including the Regional Storm. On June 6, 2008 the Ministry of the Environment issued a Certificate of Approval to the Region of Peel to construct, operate and maintain the prescribed infrastructure, including a condition (No.4) requiring the Region of Peel properly operate and maintain the infrastructure to protect the environment. To demonstrate compliance with the MOE authorization the Region of Peel operates a monitoring program. The program showed that the facility has deteriorated and that without rehabilitation, will not provide the function as per its original design. The purpose of this project is to restore the original facility functions to protect the environment, enhance the ability of the region through improved technology to operate and maintain the infrastructure, improve the infrastructure efficiency and reduce long term maintenance costs.
