The sanitary sewer
Wastewater is the dirty water from toilets and the soapy water from sinks, showers, and laundry.
Pipes running throughout your home collect the wastewater, then it leaves your house through one pipe running beneath your home to the street. This pipe leads to the sanitary sewer system.
About the sanitary sewer system
Peel Region maintains the sanitary sewer system.
The sanitary sewer collects wastewater and sends it to a wastewater treatment facility. The facility treats the wastewater before it's returned to Lake Ontario.
Homeowners are responsible for some wastewater pipes
Homeowners are responsible for the wastewater pipes in their homes. You can keep these pipes functioning properly by keeping them free of debris, like hair and grease.
The pipe that runs beneath a home to the property line is also a homeowner's responsibility. If this pipe gets clogged, the homeowner must pay to have it cleared.
These big clogs are commonly caused by:
- Objects flushed down a toilet.
- Grease poured down the kitchen sink.
- Tree roots.
Extreme weather, such as heavy rainfall, can lead to property flooding and may cause diluted sewage to overflow if the sanitary sewer system exceeds its capacity.
