ENG., DIRECTOR HAMPTON,ONTARIO TEL.(416)263.2231 LOB 1J0 987.5039 REPORT TO THE GENERAL PURPOSE AND ADMINISTRATION COMMITTEE MEETING OF APRIL 5, 1983. REPORT NO. : WD-40-83. SUBJECT: REPORT ON CORRESPONDENCE FROM THE REGION OF DURHAM WITH RESPECT TO STORM AND SANITARY SEWER CROSS-CONNECTIONS IN THE BEAU VALLEY ESTATES SUBDIVISION IN BOWMANVILLE RECOMMENDATION: It is respectfully recommended: 1. That the Region of Durham be advised that the Town of Newcastle is willing to pay its share of the cost of eliminating storm sewer house connections to the sanitary sewers in the Beau Valley Estates Subdivision in Bowmanville; and, 2. That the Region be further advised that the Town will only participate in costs at those houses where there is, in fact, a connecting of the storm to the sanitary sewer found, rather than on a blanket 50/50 basis; and, 3. That the Region be further advised that the Town will pay fifty percent (50%) of the investigative work leading to the program of eliminating the cross-connections; and, 4. That funds to cover the Town's share of the cost of correcting the cross-connections (about $10,000) and for the investigative work (about $3,000) , for the eleven (11) connections involved, be derived from the - 2 - BACKGROUND: As a result of sanitary sewerage being found at storm sewer outfalls from the Beau Valley Estates Subdivision in Bowmanville, the Region of Durham performed an investigation in the subject area. Approximately, two hundred and sixty-six (266) homes were dye tested in the area bounded by King Street East, Simpson Avenue, and Soper Creek and it was found that eleven (11) homes were discharging sanitary sewage to the storm sewers. It can only be assumed that this is by virtue of the fact that the house sanitary connections are connected to the storm sewers with the house storm connections having been made to the sanitary sewers. Both the Region and the Town are therefore implicated in correcting the situation. REPORT: It is totally unacceptable for raw sanitary sewerage to be discharged into Soper Creek; therefore, the cross-connections of sanitary house connections to the storm sewers must be eliminated. This is a Regional responsibility. Similarily, it is unreasonable to expect the Region to continue to accept storm water being discharged into its sanitary sewers and ultimately treat it at the plant. Thus, the Town must become involved in eliminating the storm connections to sanitary sewers. - 3 - As previously indicated, an extensive investigation of the area in question was performed and it was found that about eleven (11) homes were involved in the problem. Correction of the cross-connections, if outside of the house, will cost about $2,000.00 each. If the cross-connection is inside the home, the Region proposes that the owner be responsible for eliminating same. Assuming that all of the cross-connections are outside of the home and that both the storm and sanitary connections are involved, the total corrective project will cost about $20,000.00 for which the Town will be responsible for $10,000.00. If, however, it is found that only the sanitary connection is involved, which is not very likely, the Town should take the position that it is not financially involved. Further, since this matter is of mutual interest and benefit to the Region and Town, the costs of the investigative work leading to the findings, approximately $6,000.00, should be shared equally. The problems relate to development and therefore any costs incurred should be paid from the Lot Levy Reserve Account. Respectfully submitted, R.G. Dupuis, P. Eng. , Director of Public Works.

Dupuis, P.Eng. Director of Public Works W.A.TWELVETREES,P.Eng. Commissioner of Works Dear Sir: Please quote our ref: RE: Cross Connections - Beau Valley Estates Subdivision SAN-N-1-1 Bowmanville As discussed at our meeting on March 8, 1983, of the 266 homes which were dye tested in the Beau Valley Estates Subdivision; i .e. the area bounded by King Street east, Simpson Avenue and Soper Creek, 11 homes were found to be discharging sanitary sewage to the storm sewer. The attached list summarizes the findings. Please note that the houses at 42 Hobbs Drive, 1 Wilde Court, and 14 Hailey Court, have plumbing facilities in one washroom connected to the storm drain inside the house. We suggest the Plumbing Inspector deal with these as soon as possible. Further investigation would have to be carried out on the remaining 8 houses to determine if the cross connection is inside the house or at the main sewers. The Region is prepared to carry out the work involved in correcting the cross connections at the main sewers. Because there is a strong possibility that the storm laterals are connected to the sanitary sewer where the sanitary laterals are connected to the storm sewer, we feel that the Region and the Town should each assume 50% of the cost of correcting the problem on the street. In addition, both municipalities should each assume 50% of the cost of the investigative work. We also propose that the home owner be responsible for the cost of eliminating an internal cross connection since, in all likelihood, he connected .the plumbing for the washroom to the storm drain himself. . ..2 -z- We would appreciate your comments at your earliest convenience.
