Statement From Columbia Gas Regarding Merrimack Valley Explosions
Why are we replacing pipelines?
The pipelines that bring natural gas down your street and into your home or business are often cast iron steel pipe. Just like other important parts of the infrastructure in our communities, such as highways and bridges, the age and condition of these facilities can impact their safety and reliability. While your current system has performed well, we are taking a pro-active approach to replace this aging pipe,with specially designed plastic pipe.
You will receive information at your home or business before construction begins regarding any work at your address. We know you will have many questions and we intend to answer all of them as the project begins. For now, you can refer to Frequently Asked Questions. We look forward to working with you.
A graphic of the gas pipeline system and connection to your home or business is shown below. The main line carries natural gas in pipes under the street or alley. A connection at each house or business allows gas to flow into the customer service line and into your home or business.
Rerun Steps
Steps
As the project begins in your neighborhood, we will:
REPLACE the main gas pipeline. This pipe usually runs underneath your street or alley or may be located in the tree belt in front of your home.
REPLACE the customer service line - the pipe that runs from the main gas pipeline to your home or business.
RELOCATE any indoor gas meters to the outside of the home or business. (If the meter already is outside your home or business, this step will not be necessary. Relocating your meter to the outside provides our technicians with easy access to your meter in an emergency and is a safety enhancement for our customers.
