CROSS BORED SEWER POSSIBILITY

By following the instructions below, you can help prevent a serious gas leak.

Enbridge St. Lawrence Gas has been installing gas lines using pneumatic boring tools and other trenchless technology for over twenty years.  As you may know, most municipalities have few, if any, records regarding locations of sewer lines (especially lateral sewer lines).  Enbridge St. Lawrence Gas recognizes that there may be instances where a gas line has been installed within a sewer line whose location was unknown at the time the gas line was put in.

Under normal circumstances, if a sewer line is damaged during gas line construction, a problem with the sewer line soon appears and leads to discovery of the cause of the problem.  However, when a gas line has been installed for many years without creating a sewer problem, penetration of the sewer by the gas line may remain undetected for years.

For the safety of all persons, your sewer clearing personnel should refrain from using root-cutting equipment in any sewer line before ruling out the possibility that a gas line may be involved in the blockage.  Before auguring a plugged sewer, your sewer clearing personnel must contact Enbridge St. Lawrence Gas to obtain information as to the location of gas lines in the vicinity of the sewer. Through a cooperative effort, we will likely be able to determine if the location of the sewer obstruction is in the area of any gas facilities. If it is determined that a gas line is the cause of the sewer problem, we will, of course, take immediate action to remove the gas line from the sewer and responsibly assist in completion of the necessary sewer line repairs.

Should a gas line be damaged and begin leaking while clearing a sewer line, the proper procedure to follow involves immediate evacuation of all persons in the building, notification of the local fire department, and notification of Enbridge St. Lawrence Gas.  We regularly train fire departments and other emergency personnel on how to handle such an event.

FLOODED GAS APPLIANCES

Gas control valves on furnaces, water heaters, and other gas appliances that have been under water are unfit for continued use. If they are used, they could cause a fire or an explosion. Silt and corrosion from flood water can damage internal components of control valves and prevent proper operation. Gas can leak and result in an explosion or fire. Replace ALL gas control valves that have been under water.

 

KEEP METERS AND REGULATORS CLEAR OF ICE AND SNOW

During winter months, check your outside gas meter and regulator for ice and snow build up.   The gas service regulator reduces the gas pressure before it is delivered into your piping system.  A frozen regulator may result in uneven gas pressures and cause an unsafe condition and/or unsatisfactory operation of your gas appliances.  Do not use a sharp object to remove the ice.  If you notice a significant build up of ice and are unable to safely remove it, please call Enbridge St. Lawrence Gas.

 

KEEP GAS VENTS IN GOOD CONDITION

Some heating systems and water heaters may vent into a masonry chimney.  Regular inspection of chimneys is important to ensure proper venting.  The chimney should be lined and the tile liner should be in good shape.   There should be no debris or obstruction of the flue.  Problem chimneys can be refurbished with a chimney liner in most cases.  A qualified heating contractor can properly size the liner.   Regularly check the vent connectors from your heating system and water heater to the chimney.  There should be an upward pitch, all joints secure, and no signs of corrosion.   New power vented equipment may utilize either metal or plastic vent pipe.  Again, all joints should be secure and there should be no obstruction of the outside termination fitting. 

 

UNVENTED APPLIANCES

Some appliances are designed not to be vented and are safe when properly used.  A kitchen range is a good example of an unvented appliance.  It is designed for cooking and is safe for the task, but never under any circumstances should it be used for heating.    Approved unvented room heaters are safe when properly installed and utilized.  They are equipped with an Oxygen Depletion Sensor (ODS) which will shut the unit off if the oxygen in the room falls to an unsafe level.  An unvented heater should be properly sized for the room, taking into consideration the amount of combustion air available.  Unvented heaters are designed to be supplemental heating appliances and must not be used as a primary heat source.
