How do I find where my sewer line runs?

Your sewer line typically runs from your home's main drain stack to the city connection at the street, usually following the shortest path possible. Most residential sewer lines in Ottawa run from the basement or lowest level of your home toward the front of your property where they connect to the municipal system.

Start by locating your main cleanout - this is usually a 4-inch diameter pipe with a removable cap, often found in your basement floor, crawl space, or sometimes outside near your foundation. The cleanout indicates where your main sewer line begins its journey to the street. From there, the line typically runs in a relatively straight path toward the municipal connection, which is usually located near the street in front of your home.

In Ottawa, you can contact Ottawa 311 to request the location of your water and sewer connections from city records. They can provide information about where your service line connects to the municipal system. You can also look for a water meter pit or shutoff valve near the street - your sewer line often runs parallel to your water service line, though typically deeper underground.

For precise location mapping, professional plumbers use electronic locating equipment that can trace the exact path of your sewer line underground. This is especially important if you're planning excavation, landscaping, or suspect problems along the line. A camera inspection can also map the line's route while checking its condition.

Never attempt to excavate or dig without knowing the exact location - hitting a sewer line can cause expensive damage and health hazards. If you're planning any digging projects or experiencing sewer issues, a professional line location service will save you time and prevent costly mistakes.
