Sanitary Sewer Master Plan

Background Information

The Town of New Tecumseth is initiating a Sanitary Sewer Master Plan (SSMP) Class Environmental
Assessment (Class EA) in accordance with the Town’s Strategic Plan 2019-2022. The objective of this
study is to identify short and long-term servicing strategies, identify gaps, constraints, and
system improvements for its sanitary system.

This study will provide a comprehensive capital and implementation plan for the Town to highlight
prioritized maintenance and/or upgrade projects that will be required based on an assessment of the
current demands, future growth forecasts up to 2051, and emergency response. Additionally, results
of the study will be used in support of future Schedule C MCEA Studies identified in the Master

Study Approach

The SSMP which will be completed in accordance with the requirements of Approach #2 of the
Municipal Engineers Association’s (MEA) Municipal Class Environmental Assessment (MCEA) (October
2000, amended 2007, 2011 and 2015). The SSMP is to be prepared with the level of investigation,
documentation, and consultation that is sufficient to fulfill the requirements for all Schedule A,
A+ and B projects within the Master Plan.

Model Generation

This study involves the creation of a wastewater model to be used to identify current system constraints, and ultimately forecast and evaluate potential servicing solutions. The model will be calibrated with survey information gathered during the study, including results from flow monitors and rain gauges strategically located in areas of potential growth and known limitations to reflect existing flows. This model will be developed using industry best-practices and criteria outlined in the “CIWEM Urban Drainage Group Code of Practice” (2017). An overall holistic, system-wide approach will be used to develop final infrastructure recommendations based on the wastewater model.


Consultation with the public and technical partners is an essential part of the Master Plan
process. Opportunities for input will include two Public Information Centres (PICs) and direct
consultation with the project team where requested, as the study proceeds.

The first PIC was held virtually from September 22 to October 6, 2022.

Notice of Study Commencement & Public Information Centre #1 

Notice of PIC#1 

The Town of New Tecumseth is initiating a Sanitary Sewer Master Plan Class EA Study to identify short and long-term servicing strategies and system improvements for its sanitary system. This will provide a strategic vision for the next thirty years to accommodate future growth while ensuring safe, sustainable, and optimized wastewater services.

You’re invited to attend the first Public Information Centre being held virtually from September 22 to October 6, 2022!  Public engagement is very important to us and we encourage all residents and any interested party to review the posted project information and provide input.

Below we have two ways you can view PIC#1.

First is a video presentation that is available on the Towns YouTube Channel for a duration of 18 minutes. Additionally, just the presentation slides are available to view at your convenience.

 Second is a Storymaps website display board. The website display board is designed to be interactive and provide an elegant interface with the users to convey the PIC#1 information.

Project Update November 2022

PIC #1 was recently completed, and the summary of comments received are now available on the project website.

Following PIC #1, the project team will review and consider all feedback received to support the next step in developing the preferred sanitary servicing strategy. Additionally, the Sanitary Sewer Master Plan (SSMP) will move to analyze the growth and employment forecasts from the County of Simcoe’s Municipal Comprehensive Review (MCR) once they are finalized. As a result, PIC #2, which the project team had anticipated to be held in Summer 2023, will be postponed.

To receive updates on the progress of the SSMP, please consider signing up for the project’s mailing list to be updated on the progress of this study.
