Excess Flow Valves (EFVs) are mechanical shut-off devices that can be installed in the natural gas pipe running to the gas meter at your property (the “service line”).  An EFV is designed to shut off most of the flow of natural gas automatically if the service line breaks, for example, due to an excavation accident. Stopping the flow of gas from a broken service line significantly reduces the risk of natural gas fire, explosion, personal injury and/or property damage.

You may request that the City of Social Circle install an excess flow valve on the service line to your property.


If you notify us that you want an EFV we will contact you to discuss your specific situation and the cost of installation and maintenance.  EFVs cannot be installed on your service lines if:

  • The service line does not operate at a pressure of 10 psig or greater throughout the year;
  • The EFV could interfere with proper operation or cause loss of service;
  • An EFV could interfere with necessary operation or maintenance activities; or
  • The capacity of the meter on the service line exceeds 1,000 cubic feet per hour

If you request an EFV we will inform you if your service line cannot accommodate an EFV.


If an EFV can be installed on your service line and you choose to have this done, we will set up a mutually agreeable date when we will install an EFV on your service line.

You will be billed $275 to cover the cost of installing the EFV.


If it becomes necessary to maintain or replace the EFV on your service line you will be billed $275.
