Casa Grande
A Message to Our Customers Regarding Odorant Levels in Casa Grande
Southwest Gas is experiencing a low odorant level in its pipelines impacting its distribution system from Casa Grande west to Gila Bend. Under proper conditions, a natural gas leak will smell like rotten eggs. Until further notice, individuals in the affected area should not rely exclusively upon their sense of smell to detect the presence of natural gas. Under current conditions, it is especially important that the public be alert to other signs of a potential leak that include hissing or blowing sounds, standing water continuously bubbling, dirt or water blowing in the air, or decay in vegetation. If anyone suspects a gas leak, please call 911 and Southwest Gas at 1-877-860-6020. For those individuals who are performing work on natural gas piping or are installing natural gas appliances, please go to for important safety information. For any work that requires purging of natural gas lines, such as the installation of new gas lines or the installation of certain appliances, it is essential that purging operations be performed properly, either by: 1) Directing purged gases to a safe location outdoors and away from people, structures, or ignition sources; or 2) Directing purged gases to the indoors or the outdoors, and monitor the point of discharge with a combustible gas detector. Failure to follow these instructions on purging could result in injury and property damage resulting from fire or explosion. Additional information on purge safety can be found in the 2012 edition of the National Fuel Gas Code. Southwest Gas is diligently working to correct the condition.
