Customer-Owned Yard Line (COYL) Programs

English | EspaƱol

What is a COYL?

COYL, or Customer-Owned Yard Line, is the primary gas line running underground from the meter to your home or business. Unlike most natural gas pipes, which are owned and maintained by Southwest Gas, this piping is owned and must be maintained by the property owner. 

In newer homes or businesses, the meter is typically located close to the structure and the amount of gas line owned by a customer is minimal. 

However, in many older structures, the meter is set away from the building, and the customer is responsible for a larger portion of the gas line.

Some properties may contain more than one COYL. Secondary COYLs may exist for outdoor appliances such as barbeques or pool heaters and are not included in this program.
Not every property has a COYL, so take a look at your meter location. If the meter is located some distance away from the structure, you may qualify to have it relocated as part of the COYL program.

How the COYL Program Can Help You

Your safety is our priority. COYL programs are part of that commitment to safety. The natural gas line running between the meter and your home or business is your responsibility. This means it’s up to you to have the line inspected for leaks and pay for repairs if an unsafe condition is found. That’s why Southwest Gas has programs to help take that burden away.
