Programs and Services
A Capital project is an infrastructure project that maintains, renews or improves a City service.
Mississauga staff manages the stormwater service and program with the planning, construction, operation and maintenance of stormwater drainage infrastructure.
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 minimize potential risks to you, your property and the environment though the stormwater service and program. 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.
Ongoing Programs and Services
Watercourse Monitoring and Pond Maintenance
Watercourse is the word used for both constructed channels and natural creeks and rivers. In many cases, watercourses have a combination of man-made and natural features.
City staff regularly monitor our watercourses looking for drainage problems or erosion where creek banks may slowly wash away. They inspect watercourses for changes, record measurements, fill out evaluation forms, and map and photograph any problem areas. This information is used for the City’s Storm Drainage and Watercourses maintenance and capital programs.
Stormwater ponds are meant to collect sediments and pollutants over time and these materials must be removed every 10-15 years to keep the ponds working. City-owned stormwater ponds are inspected regularly and sediment removal projects are scheduled into the City’s capital program. Learn more here.
The City monitors rainfall with the use of 14 tipping bucket rain gauges across Mississauga; they measure how much rain has fallen and over how long a period of time. This data helps to calculate the strength of the storm and how often storms that strong will happen again in the future. Learn more here.

Encroachment on Public Lands By-law 0057-2004
When making changes or additions to your property, it is important to stay in your property’s limit and not extend onto public property. Encroaching on City property can interfere with lot drainage, City maintenance and natural green space and limit the use and enjoyment of that public property. Learn more here.
