​​​​Water & Wastewater Treatment Centre​​

​​​​​​​​​The Town operates a state of the art sewage treatment facility, which was last upgraded in 1995 at a cost of approximately $6.5 million. The upgrade works included:​

  • addition of (egg) digester as final stage biosolids treatment
  • addition of 1 primary treatment clarifier
  • addition of 1 storm equalization tank
  • addition of laboratory and office space
  • upgraded SCADA computer controls

The treatment plant also has facilities to receive septa​ge and holding tank waste as well as being a receiving site for recreation vehicle head waste.

 Water Operations & Treatment

What we do...

​The Town's water distribution system spans approximately 97.30 kms.​ of water mains​ and serves approximately 5,400 residential and commercial customers. In addition, there are approximately 475 fire hydrants located within the municipal boundaries.

The Town of Midland's Water and Wastewater Operations facility leads the provincially licensed Water Department in providing a variety of services to consumers within the municipal boundaries.​


  1. Operation, repair and maintenance of the Town's water distribution system, including emergency repairs.
  2. Daily, weekly and quarterly water testing and monitoring per O.Reg. 170/03.

  3. Repairs to and replacement of all water meters.

  4. Repairs to and installation of new water services and water main projects.

  5. Flushing in excess of 475 fire hydrants and dead end water mains within the system.

  6. Water billings.

Water Treatment

​The Midland water system includes numerous wells, one high lift station, two booster pumping stations and four storage reservoir sites. Not all of the wells are currently active. The water system serves a municipal population of approximately 16240.

Two main pressure zones are presently required due to the topography of the community.

All areas of the grid system are linked including the Portage Park water system, which was transferred to the Town of Midland from the Township of Tay in 1998.​

Unidirectional Water Main Flushing

As part of our ongoing commitment to safe drinking water the Town of Midland Water and Wastewater Services normally conducts a unidirectional water main flushing program from May to October.  This maintenance activity ensures we continue to provide the highest quality drinking wat​er within our water distribution system.​

For more details on this program, please visit our Unidirectional Water Main Flushing web page.

 Drinking Water Quality Management System

What Is A Quality Management System?

​A quality management system consists of policies, procedures and objectives that direct and control an organization with respect to quality. ​

Why Does The Town of Midland Need One?

​Justice O’Connor recommended in the Part Two Report of the Walkerton Inquiry that a new approvals framework for municipal drinking water systems, which would require owners to obtain a license to operate their systems as well as incorporate the concept of quality management into their operations, be adopted. To meet this recommendation, the Ministry of Environment (MOE) developed the municipal drinking water licensing program, implemented under the Safe Drinking Water Act, 2002 (SDWA), and one part of this licensing program was the creation of the drinking water quality management standard (DWQMS). In order to be licensed to provide drinking water, a municipality must have a quality management system in place that meets the requirements of the DWQMS. ​

Quality is Key!

​As a Supplier/Contractor you need to know that the product or service you are contracted to provide to the town must meet specific quality requirements that will aid the Town in continuing to provide safe drinking water to all users of its drinking water system.

Pay attention to your purchase order or tender document!

​Specific quality requirements will be noted on your purchase order or tender document, and may include a requirement that you provide a certificate or other document when you deliver the product or service. (i.e. Certificate of Analysis for calibration standards) ​

We may want to see what you do!

​Additionally, you or your personnel may be subject to an on-site verification audit where Town personnel will observe how you complete your task, and will document that you are following the regulated procedures (i.e. water-main disinfection after repair or construction)

As a Supplier/Contractor what do I need to know and what do I need to do?

​Suppliers and Contractors play an important role in helping the Town of Midland ensure that safe drinking water is provided to all consumers.

Quality Management System Policy

Sanitary Sewer Backwater Valve Subsidy Program

​Click here to visit the Sanitary Sewer Backwater Valve Subsidy Program webpage for more details and the application.​

The impact of climate change continues to present an unprecedented challenge to municipal infrastructure given both the intensity and severity of current storm events.  The implications of climate change are placing greater challenges upon local municipal infrastructure budgets, both operating and capital. The Town has been engaged in a program of replacing combined sanitary sewer and stormwater systems through the allocation of the annual capital budget program. 

Due to the Town's limited financial capacity, replacement efforts will take many years to complete the upgrades. This concern has prompted the Town to create a backflow prevention subsidy program aimed at assisting homeowners to take reasonable steps to prevent flooding events before the municipality is able to replace the combined sewer and stormwater infrastructure. it is essential that homeowners take the appropriate action to reduce the risk of basement flooding on their own private property.  Homeowners may be able to reduce the impact by installing a backflow prevention device on their sanitary sewer system.

Notice - Avoid Sales Scams

Sewage System

The extension of sanitary sewers to the Sunnyside area may be contemplated at such time as development in the Bayport area occurs. Extension to the Midland Point and Portage Park areas is not under consideration.

In Midland, as elsewhere, it costs more to collect and treat sewage than to provide potable water, and also because:

  • 8 million dollar plant expansion and upgrade for a better effluent to protect Georgian Bay, as well as to facilitate the growth​ and development needed to enhance our economic base.

  • Increased operating costs.

  • Avoid tax increases by continuing user-pay policies (note, sewage treatment is not tax based, but relies on sewer service rate revenues).

  • Tracks with other municipalities, i.e.​ Midland's average residential rate of $8.00 per month versus $19.00 per month for surrounding areas.

Control your costs through water conservation:

  • When replacing fixtures, use low water consuming units:  

    • Low flush volume toilets

    • Water efficient shower heads

  • Use water efficiently:  

    • Operate washing machine and dishwater with full loads.

    • Avoid lawn watering; cut lawn higher during dry periods.

    • Repair leaking faucets and toilet flush values. 

Water Efficiency Programs

​The Town of Midland is striving to promote water conservation awareness to our residents. By reducing our water production we save energy and reduce greenhouse gas emissions. We have compiled an information guide suggesting ways in which we can employ this awareness in our everyday lives. Together we can demonstrate environmental leadership by conserving water both indoors and outdoors. For tips and information about water efficiency programs click on the images below.​

Cross Connection Control Program

​Purpose of the Program

The Town of Midland Backflow Program has been established to help ensure the supply and distribution of safe, clean drinking water to all our users.  The program is designed to achieve the following:

  • Identify any  all cross connections where potential contamination of potable water may occur.

  • Maintain a database of qualified backflow device testers


Backflow: means the flowing back of or reversal of the normal direction or flow of water

Backflow Prevention Device: means a device that prevents backflow including a Reduced Pressure Principle Assembly, a Dual Check Valve or a Double Check valve and the like

Cross-Connection: means any actual or potential connection through which a non-potable (contaminated) fluid can flow into a potable (safe) water system. Backflow is the fluid which flows through the cross connection into the potable water system.
