There are many different kinds of companies providing services related to natural gas. Here's where we fit in at Columbia Gas. It's our responsibility to deliver natural gas to warm your home, heat your water and cook your food. And to maintain the gas lines used to deliver that gas to your home or business. In order to deliver natural gas to the many homes, schools, hospitals, stores, business and factories in your community - and across the state - we have thousands of miles of gas lines in our system. These natural gas lines are an essential part of our modern-day infrastructure and, as with other types of infrastructure like roads, damns and bridges, deterioration occurs over time and repairs or replacement are eventually needed.

For many natural gas lines, that time is now. The old gas lines installed in your neighborhood generations ago served us well, but they are now ready to be retired. That's why we launched an ambitious natural gas line replacement program. If we do nothing, the cost to maintain and repair these older gas lines will be higher than the cost to replace them. That wouldn't make sense, so we're taking proactive steps now to reduce costs to customers. Thanks to advancements in technology since those old gas lines were first put into service, we now install specially designed, long-lasting lines more suited for underground use. They contract and expand with shifting temperature and bend to the contour of the earth around them. As a result, these new gas lines will not only last longer, but will also require less maintenance. All of which saves money and allows us to maintain the safe, reliable and efficient natural gas delivery service you currently rely on each day.

As with any infrastructure improvement project, upgrading our natural gas delivery system may result in temporary inconveniences while work is underway. If work is underway in your area, we thank you for your patience and ask you to keep the long-term benefits in mind. You will receive notification through a letter, and either a door hanger or personal visit from a Columbia Gas employee or contractor well before any work on or near your property begins. When you see the flags and paint markings identifying the locations of underground gas lines and other utility lines, it's likely work will begin soon.

We often use innovative line replacement techniques to limit the amount of digging required. When upgrading your service line, we may relocate your gas meter outdoors if it's currently inside your home. Our goal is always to keep any service interruption to a minimum. You'll be notified in advance of any temporary service interruption, which typically lasts only several hours. Care and caution are taken throughout the entire process, ensuring your safety and limiting any inconvenience.

After a natural gas line is replaced, we completely restore the area to its original or better condition. We do our best to coordinate our natural gas replacement work with other infrastructure projects to minimize inconvenience. Public property, like streets and sidewalks, is rebuilt to local government requirements. Restoration may include new sidewalks, freshly paved roads and Americans with Disabilities Act compliant curbs, depending on the location of the project and local ordinances. At Columbia Gas, we see our natural gas line replacement program as an investment in the communities we serve. The upgrades we're doing now are part of our ongoing commitment to reliably deliver your natural gas, safely and efficiently, for generations to come.

Will you block my street or driveway?

We may temporarily block access to an entire street, lane or even a driveway. If you need access to your driveway, let our crews know. When it is safe to do so, they will accommodate your request. Most of our digging will be in the grassy part of the public right-of-way and yards, but often our equipment is in the street while we are working. We will work with neighborhoods to minimize road closures and blockages, but please be alert and use caution around our work zones.

Thank you for your response.

Will I have to pay extra for this project?

When and how long will my gas be turned off?

Your gas service will be temporarily turned off when we come to work on your meter. If your meter is already outside, your gas service may still be turned off when we connect your service line to the gas main line. This outage will be brief, usually between 2–4 hours. Once we’re done, we will need to get back inside your home or business so we can perform a safety check of your natural gas appliances and inside gas lines, turn on your gas and relight your appliances. Note: Someone 18 years or older must be at your home or business and pets must be secured when we’re there to work on your meter and turn your gas back on.

Thank you for your response.

Thank you for your response.

What can I expect?

You will first notice our representatives conducting preliminary work to ensure that pipelines are installed in the least invasive way possible. This will include locating and marking all underground utilities, such as water and cable. Next, we usually replace or add main lines along a street or right-of-way. We then construct service lines that connect the mains to homes or businesses. As a safety measure, we may also replace older indoor gas meters with new outdoor meters.

Thank you for your response.

Will you need to dig up my yard, sidewalk or driveway, and if you do, who’s going to fix it?

Because all natural gas pipelines are buried, some digging will be necessary. We will try to minimize the amount of digging required. If we disturb your yard, sidewalk and/or driveway, we will repair affected areas as soon as weather permits. Initial restoration, such as leveling of surfaces, will be completed as the project progresses.

Thank you for your response.
