We know dealing with a blocked sewer or flooded basement can be a major pain that you want dealt with quickly. But it's important to remember to always "Call Before You Clear".

Underground natural gas pipelines unintentionally installed through sewer or septic pipes are called cross bores. Left undisturbed, cross bores aren’t an immediate safety risk. However, cross bores can result in a dangerous natural gas leak if equipment used to unclog sewer or septic pipes (rotating or water jet equipment) damages the natural gas line.

Clearing clogs in the pipes that run within your home is safe to do. But it is very important to have the sewer lines that run outside the walls of your home inspected before you or a contractor attempt to clear them to avoid a real and immediate risk to public safety, including a gas leak, fire or explosion.

Our steps towards keeping you safe...

When we install natural gas pipelines, we are required to identify and locate private sewer lines that may potentially intersect with the new natural gas pipeline, to ensure we install it safely. This inspection may require access to the sewer lines from inside homes, even if your home is not connected to natural gas.

If we are in your neighbourhood, we may need access to your basement to complete the inspection. We will provide you with notification. All our service technicians can be identified by an Enbridge Gas licensed contractor photo identification card.
