Drinking Water Treatment & Distribution
The Town of Innisfil provides safe, reliable drinking water to residents and businesses. InnServices treats, tests, and delivers drinking water from its source to your tap and maintains the system to meet provincial standards.
Where Your Drinking Water Comes From
Innisfil’s drinking water comes from two sources:
- Groundwater from municipal wells in Churchill, Stroud, and Innisfil Heights
- Surface water from Lake Simcoe, treated at the Lakeshore Water Filtration Plant
Water from these sources is treated and tested to ensure it is safe before entering the municipal distribution system.
Delivering Water to Your Home
After treatment, drinking water travels through underground pipes to homes and businesses across the community. The system operates continuously to provide reliable service and maintain water quality.
Maintaining Safe and Reliable Service
InnServices regularly maintains the water distribution system to protect water quality and prevent service disruptions.
Watermain Flushing
Watermain flushing removes mineral deposits and sediment from inside water pipes to help maintain water quality and improve system performance.
During flushing, residents may notice temporary discolouration or air in the water. This is normal, temporary, and does not pose a health risk. Running a cold water tap for several minutes usually clears the water.

Hydrant Maintenance
Fire hydrants are an important part of the drinking water system. They support emergency fire protection and are also used for system maintenance activities such as watermain flushing.
InnServices inspects and maintains municipal hydrants year-round to ensure they are ready for emergency use.
Help Keep Hydrants Clear Year-Round
Residents can help emergency crews by keeping hydrants visible and accessible:
- Do not block hydrants with vehicles, landscaping, or structures
- In winter, clear snow and ice around hydrants on or near your property
- Maintain at least 1 metre (3 feet) of space around hydrants where possible
Keeping hydrants clear helps ensure quick access during emergencies.
Exercising Valves
Mainline valves throughout the distribution system are exercised regularly to ensure they operate properly during maintenance or emergency shutdowns and to help maintain reliable service.
During maintenance activities, residents may notice temporary changes such as discoloured water or pressure fluctuations. These effects are typically short-term and do not pose any threat.
