Municipal Class Environmental Assessment Study Highway 404 North District Water Supply, Pressure District 7 (PD7)

Share on Facebook Share on Twitter Share on Linkedin Email this link

Introduction

The City of Markham has initiated a Municipal Class Environmental Assessment Study across the Highway 404 North District Water Supply, Pressure District 7 (PD7).

The study will identify alternative design concepts and a preferred alignment for watermain connection from the Richmond Hill water network to the Markham PD7 water network across Highway 404, and north of Elgin Mills Road.

The study is being conducted in accordance with the planning and design process for Schedule 'B' projects, as outlined in the Municipal Class Environmental Assessment (MCEA) process.

The objective of the Highway 404 North District Water Supply (PD7) MCEA Study is to meet the following principle goals:

  1. Review alternatives for the watermain extension
  2. Consideration of ongoing and completed studies and master plans
  3. Compliance to standards, policies and regulations
  4. Constructability
  5. Natural, social, and cultural environments
  6. Cost efficiency


Study Area

Background

The Regional Municipality of York supplies water to nine (9) area municipalities including the City of Markham and the City of Richmond Hill. In turn, Markham delivers water to individual consumers.

Markham’s existing PD7 water system is supplied by the Region’s system via a single transmission main from Elgin Mills Road East and Highway 404.

The 2016 York Region Water and Wastewater Master Plan (currently under review) includes a future North Markham Water Servicing project (W20) and this project will provide a long-term secondary water supply for PD7. However, this project is scheduled for commissioning between 2031 and 2035.

The proposed project includes a new PD7 pumping station at the North Markham Reservoir, and 10 km of watermain from the new PD7 pumping station and the existing PD7 water system at Elgin Mills Road and Woodbine Avenue.

Markham is proposing a short-term solution to provide a secondary water supply for PD7 by looping a watermain with the Richmond Hill watermain across Highway 404 until a long-term solution is developed, funded, and constructed by the Region.

The purpose of the Municipal Class Environmental Assessment Study is to identify alternative design concepts and a preferred alignment for the watermain connection from the Richmond Hill water network to the Markham PD7 water network across Highway 404, and north of Elgin Mills Road.


Next Steps

  • Outlining project schedule
  • Determine key dates
  • Set up public consultation PC1 and PC2
  • Working with project consultant to review preferred alignment alternatives
  • Keeping this project page updated with the latest project information

The City of Markham welcomes feedback, questions and comments pertaining to this project.
