Background

The Bathurst Langstaff sewer is a critical component of the York-Durham Sewer System (YDSS). It will move wastewater from the Maple Relief Sewer to the York Durham Sanitary Sewer (YDSS). These sewers will also provide sewage capacity for the urban development that is taking place west of Bathurst Street and north of Langstaff Road.

Bathurst Trunk Sewer Phase 2 & 3   Background This construction project forms part of the York Durham Sewer System (YDSS), and is being undertaken by the benefiting land developers groups.  A Development Charge Credit Agreement has been established between York Region and involved developers groups.    Phases 2 and 3 of the Bathurst Trunk Sewer Project will extend a sanitary sewer northerly from Autumn Hill Boulevard to Mill Street.  This will provide sanitary services for new development occurring in the City of Vaughan.      Phase 2   Phase 2 extends on the west side of Bathurst Street from Autumn Hill Boulevard northerly and then internally through the future developments west of Bathurst Street to Major Mackenzie Drive.  The Class Environmental Assessment (EA) for this phase outlines conditions that call for increased public consultation and technical analysis.  Additional technical analysis includes investigation of potential dewatering impacts, where dewatering is required.  Please see the letter from the Minister of the Environment , dated October 1, 2004 for details on these and other conditions. Click here for more information on Phase 2   Phase 3   Phase 3 starts where Phase 2 finishes at Major Mackenzie Drive and runs east along Major Mackenzie Drive to Bathurst Street and then north on the west side of Bathurst Street to Mill Street.  A Class EA Addendum has been completed for this phase.  The conditions outlined by the Minister of the Environment for Phase 2 will be applied to Phase 3 as well.

Most of this growth was planned around the existing urban centres of Aurora, Newmarket, Vaughan, Richmond Hill, and Markham. To support this development, increased capacity in the York Druham Sewage System (YDSS) is required. The 16th Avenue Trunk Sewer Phase II is a key phase of construction to complete the paralleling of the YDSS through the Town of Markham by connecting to the existing Highway 404 Trunk Sewer located just east of Woodbine Avenue.   The method of construction used for the 16th Avenue Trunk Sewer System is tunneling. Due to the magnitude and complexity of the project, it was advertised in international tunneling magazines in order to attract tunnel contractors worldwide to submit pre-qualification proposals for the project. The McNally/Aecon Joint Venture (JV) was the successful bidder and was awarded the 9th Line Trunk Sewer Project, a Design/Build Contract, by York Region. The construction of the parallel sewer system started in 2000. To date, the design/build team has successfully completed the 9th Line Trunk Sewer and the Phase I portion of the 16th Avenue Trunk Sewer. The location map shows the 9th Line project as well as both Phase I and Phase II of the 16th Avenue Trunk Sewer project.   In order to safely construct the shafts and the tunnels of this sewer to the required depth, the groundwater level must be lowered by pumping in the deep aquifer to below the depth of the shaft and tunnel. An extensive Environmental Management Plan has been developed to deal with any negative impacts resulting from the project.   please click here for  more information   16th Avenue Trunk Sewer Project   19th Avenue (YDSS Interceptor) Background   Background information from the Environmental Assessment for the 19th Avenue Interceptor Sewer Project:   During the 1990's the Regional Municipality of York (the Region) experienced the highest growth rate in the Greater Toronto Area (GTA). By 2026, the population of the Region is expected to reach 1,280,000. Currently, 94% of the Region's existing population relies on sanitary services provided through the York-Durham Sewerage System (YDSS). Planned population and industry are expected to generate sewage flows and water servicing beyond the existing capacity of the YDSS.   In 1997, the Region completed the Master Plan Study for the YDSS. This Master Plan was completed to identified and reviewed current conditions and future alternatives necessary to meet population projections in the Region. This Master Plan identified several priority and strategic projects to be implemented during the planning period of the Master Plan. In March 2002, the YDSS Master Plan was updated to reflect current planning forecasts and to confirm the timing of required infrastructure   please click here for  more information   YDSS_INTERCEPTOR Public Information Forum, April 26th YDSS Interceptor Project   King City Sanitary Servicing Background   In the fall of 2003, King Township Council and York Regional Council agreed upon a solution to the problem of septic system failures in King City – hooking King City residents to the York Durham Sewage System (YDSS).   please click here for  more information   King City Sanitary Servicing Duffin Creek Water Pollution Control Upgrades Background Through a Schedule C Municipal Class Environmental Assessment, York and Durham Regions are undertaking a joint study to develop a wastewater treatment strategy for the Duffin Creek Water Pollution Control Plant (WPCP). This strategy will allow York and Durham Regions to provide wastewater servicing to official planned growth and to continue their efforts to improve the quality of effluent going into Lake Ontario.   Click here for more information   South East Collector Background   The Southeast Collector Trunk Sewer is a critical component of the YDSS that moves wastewater from York Region to the Duffin Creek Water Pollution Control Plant (WPCP) located in the City of Pickering.   The project is currently in the Individual Environmental Assessment (IEA) phase. The Terms of Reference document has been circulated for comment. Comments can be provided on the project web site. Additional information will be provided as the project proceeds.   Link to Media Releases
