COVID-19: latest updates on the City's response and service impacts
Stormwater Charge

Stormwater Charge

A new stormwater charge appeared on Region of Peel water bills for Mississauga properties beginning in 2016. To learn more about stormwater, how the City manages this service and the charge, please watch the video.


What is Stormwater?

Stormwater is the rain and melted snow flowing from our properties on to our streets and down into more than 51,000 storm drains. This water flows through a large and complex network of pipes and waterways directly into Lake Ontario.

Our stormwater drainage system protects water quality and lowers the risk of flooding that can damage your property and the environment. To keep our system in good working order, the City invests in planning, design, construction, operation, maintenance, renewal and by-law enforcement activities.

Our Challenge

Mississauga is a growing city. With more people living here and more businesses operating here, the amount of water running off hard surfaces such as roofs and parking lots is increasing. In addition, changes to our climate can bring heavier rainfalls and rapidly melting snow. These changes mean there is more stormwater entering our system than ever before, causing costly wear and tear on our already aging infrastructure.

We want to minimize potential risks to you, your property and the environment. We need to invest more money in our stormwater system to keep it in good working order and to avoid costly repairs in the future.

Our Solution

The City did a study with input from the public in 2012 to find the best solution for Mississauga. This study found a stormwater charge to be a fair and dedicated source of funding that is needed to manage stormwater now and in the future.

What is the Stormwater Charge?

The stormwater charge is a dedicated source of funding that appears on the Region of Peel water bill.

If you own a property in Mississauga, you will see the stormwater charge appearing on your Regional water bill.

The charge will be identified on the bill as a Stormwater Charge and will show the number of billing units for the property, the daily rate being charged, the total number of days included in the bill cycle along with the total Stormwater Charge amount.

The approved 2020 rate takes effect as of April 1, 2020.


STORMWATER CHARGE 0.7 UNITS x 0.2964384 x 90 DAYS = $18.68

Residential Program Workshops

On April 13, 2016 staff held two public workshops to collect input on potential options for programs that would recognize and encourage stormwater best management practices on residential properties. Thank you to the nearly 200 Mississauga residents who participated and offered their ideas.

The workshop focused on table top discussions about the following two questions:

  1. How do you think the City should recognize homeowners who take steps to manage stormwater and reduce the risks of flooding on their properties?
  2. What type of resources and guidance do you think would help homeowners take steps to manage stormwater and reduce the risks of flooding on their properties?

Ideas and suggestions from participants were documented by table facilitators and will be considered by the working committee, along with emails we received after the workshop, to form recommendations that will come forward in a public report to General Committee of Council.
