'\. ,,, REPORT NO.: EGD-41'()2 PAGE 2 1.0 BACKGROUND On April 2, 2002 the Operations Department, responding to a call placed by the residents of 5487 Old Scugog Road, completed some temporary work to the storm sewer system on the east side of Old Scugog Road opposite Mill Street. The works completed were required to address a sewer surcharge issue that resulted in the flooding of the basement of 5487 Old Scugog Road, Hampton. The temporary works were to remain in place until a thorough survey and review of the possible causes for the surcharge could be conducted. On April 15, 2002 a detailed survey of the area and the subject storm sewer was conducted. Upon review of the survey it was determined the potential cause of the storm sewer surcharge was a partial collapse of the corrugated steel storm sewer pipe between the outlet south of Mill Street and the catch basin south of 5487 Old Scugog Road. Subsequent to the review and analysis a design was completed to address the storm sewer surcharge issue while trying to minimize costs to the Municipality. 2.0 COMMENTS The proposed design requires that the partially collapsed corrugated steel pipe be replaced from the outlet to the catch basin south of 5487 Old Scugog Road with a smooth walled high-density polyethylene pipe of the same diameter. This will address the surcharge issue that has been temporarily remedied by the Operations Department. In addition to the replacement of the above noted section of pipe the next upstream section of pipe has also been included for replacement in the proposed design as a measure of preventative maintenance. Although this pipe has not shown signs of collapse it is of the same age as the downstream section of pipe and should be replaced. 718 .. "'l ""t- ~ REPORT NO.: EGD-41..o2 PAGE 3 The proposed design also includes for the reconnection of all existing storm sewer connections encountered while completing the replacement work. All disturbed areas will be restored to their original state. The estimated cost associated with the completion of the remedial works noted above is approximately $35,000. The Operations Department would typically complete a project of this size but due to their current workload it is recommended that the work be tendered for completion by a private contractor. The close proximity of existing underground telephone, cable t.v. and gas utilities, and the liability associated with damaging them, make this project a better candidate for work by a private contractor than some of the other projects to be completed by the Operations Department this fall. As this work was not a budgeted maintenance or capital works project, funding for the project must be obtained.
