By now most are aware that Eversource is bringing natural gas to New Canaan, so I thought it was a good time to provide some basic information about “gas.”

The following are some basic facts about natural gas:

  • Natural gas is a lighter than air gas, when released into the atmosphere it rises and dissipates. Propane is a heavier than air gas so it sinks when released.
  • Both natural gas and propane have an odorant (ethyl mercaptan) added because in their natural states they are odorless, colorless and tasteless. That is the “rotten egg” odor we know as “gas.”
  • As with propane, natural gas may be used to feed multiple household appliances—for example, water heaters, stoves, pool heaters, fireplace logs, grills, furnaces, boilers and generators. 
  • Most propane equipment can be converted to use natural gas by licensed technicians.
  • All gas installations, from the gas meter into the building, require a permit from the New Canaan Building Department and must be completed by licensed technicians. Eversource is responsible for all work from the street to the gas meter.
  • If you smell gas (rotten egg smell), leave immediately, and call 911. The Fire Department has gas detecting equipment and if necessary, may turn off the gas supply.
  • If desired gas alarms are available to be installed in buildings where gas is in use. Be sure to follow manufacturer’s instructions for use and installation.

The ongoing construction schedule is posted on the town website. For further information about natural gas go to Eversource’s site or contact the New Canaan Fire Marshal’s Office at 203-594-3030.
