         Introduction

        The Region of Durham has determined that a new trunk sanitary sewer is necessary to
        meet wastewater servicing requirements within the Courtice Water Pollution Control
        Plant (WPCP) service area.

        A Class Environmental Assessment (EA) study will be completed to determine the
        preferred servicing alternative for the Courtice Trunk Sanitary Sewer.

        This study is classified as a “Schedule B” project under the Municipal Class EA Process.
        This process involves stakeholder consultation.

        The process will include an evaluation of all the impacts (natural, cultural, socio-
        economic and environmental) associated with each alternative and will address all
        related stakeholder concerns.




 Introduction to the Study

                                                                                                                                         Works Department
                                                                                                                                         www.durham.ca

                                          In accordance with the Region of Durham’s Official Plan, future growth is planned for North Whitby (Brooklin), North
                                           Oshawa and Courtice.
                                          A new trunk sanitary sewer will be required to convey the sanitary sewage flows from existing and new development
  Why Is This Sewer Required?              areas to the Courtice Water Pollution Control Plant (WPCP).
                                          The proposed Courtice Trunk Sanitary Sewer was identified as an infrastructure requirement in the planning &
                                           construction of the Courtice WPCP.



                                          The Courtice Trunk Sanitary Sewer study area is bounded by Conlin Road, Solina Road, Harmony Road, and Lake
        Study Area Boundaries              Ontario.
                                          Boundaries were established based on wastewater conveyance needs.



                                          The Harmony Creek WPCP and Courtice WPCP currently treat sewage flows generated from Oshawa and Courtice.
                                          The Harmony Creek WPCP will ultimately be decommissioned, leaving Courtice WPCP to service all of Oshawa and
                                           Courtice.
           Servicing Strategy             The proposed Courtice Trunk Sanitary Sewer may require local sanitary sewage pumping stations to service low lying
                                           areas.
                                          In the future, sewage flows will be conveyed to the Courtice Trunk Sanitary Sewer from both the Conlin Road Sanitary
                                           Sewage Pumping Station and the future potential Thickson Road Sanitary Sewage Pumping Station.


                                            The Courtice WPCP is located east of Courtice Road and along the Lake Ontario shoreline.
                                            The Courtice WPCP was commissioned in 2007 with an existing rated capacity of 68,200 m3/d.
              Courtice WPCP                 Wastewater treatment at the Courtice WPCP is approved to service approximately 150,000 people.
                                            Presently, sanitary sewage flows are conveyed from the Harmony Creek Sanitary Sewage Pumping Station via a
                                             forcemain.

                                    Class EA Study




      The following considerations were used to determine the seven potential Courtice
      Trunk Sanitary Sewer alignments:




      • Conlin Road E & Courtice WPCP: The sanitary sewer must start at Conlin Road and
       terminate at the Courtice WPCP in order to service future growth areas.

      • Utilization of Existing Infrastructure: A key objective in determination of the potential
       alignments was the utilization of the existing sanitary sewer network such as the segments of
       existing sanitary sewer along Coldstream Drive and Townline Road North.

      • Nash Road Sanitary Sewerage Pumping Station: Consideration was given to
       decommissioning the Nash Road Sanitary Sewerage Pumping Station by conveying flows
       from its current service area to the proposed Courtice Trunk Sanitary Sewer.

      • Avoidance of Busy Streets: High traffic streets and intersections (such as King Street) were
       avoided to the extent possible to alleviate congestion during construction.

      • Avoidance of Major Creek Crossings: Potential alignments were planned to avoid major
       creek crossings to the greatest extent possible, such as the Farewell Creek on Townline
       Road and Nash Road.

      • CP Rail Crossing: In order to reach the Courtice WPCP, the sanitary sewer will have to
       cross the CP tracks. The majority of the alignments cross at a location that will minimize
       constructability issues.

      • Highway 401: In order to reach the Courtice WPCP, the sanitary sewer will have to cross
       Highway 401. Potential alignments were determined to minimize constructability issues and
       utilize existing road allowances.

      • The Greenbelt: A key consideration in the determination of the potential alignments was
       avoiding key natural features associated within the area designated as Greenbelt.

  Potential alignments were based on the following preliminary screening
  criteria:




    1. Utilize existing road            2. Minimize impact on Natural
       allowances, open space and          Environment such as
       existing utility corridors as       watercourses, green spaces
       much as possible                    and other known features




      3. Minimize impact on social          4. Ability to connect with the
         and cultural environments             existing sanitary sewer
                                               network
