What We Do

 


  • Damaging an underground facility is not only dangerous, but it can cause outages, expensive repairs and legal action. To help minimize the amount of damage that may occur to our natural gas distribution system, we have a group of highly trained individuals who help protect our system from damage. These employees go through very strict operator qualification classes throughout the year at our state-of-the-art training center in Concord.

    We also help promote Dig Safe, a not-for-profit clearinghouse that notifies participating utility companies of consumers or business’ plans to dig. In turn, these utilities (or their contract locating companies) respond to mark out the location of their underground facilities. This helps others know which areas to avoid when digging therefore helping to keep our underground infrastructure safe.

  • The natural gas pipeline infrastructure is the nation's safest energy delivery system. Liberty Utilities has experienced personnel that routinely inspect and maintain natural gas service lines. Service crews are available to respond to emergencies 24 hours a day, 7 days a week.

  • Excess Flow Valves are safety devices that are installed on some service lines to minimize the flow of gas in the event a service line was damaged. Click below to see if your service line is eligible to have an EFV installed.

  • Liberty personnel monitor our gas distribution system and take emergency calls 24/7 from our local Gas Control Center in Londonderry, NH.

  • Every year, we replace approximately 15 miles of cast iron and bare steel gas main. Replacing aging pipe with new pipe helps maintain the reliable services that we have always offered and decreases the amount of leaks that could occur.

  • Although we replace approximately 15 miles of cast iron and bare steel main with plastic main every year, a large portion of pipe in our service territory is coated steel. In order to increase the lifetime and maintain the safety of coated steel piping, our corrosion engineer is dedicated to protecting steel pipes from corroding through periodic corrosion testing and by installing and maintaining cathodic protection devices.

  • To keep our natural gas distribution system both safe and reliable, we conduct multiple inspections and surveys every year.

  • For every job we do, supervisors write a Standard Operating Procedure (SOP) for the crews that will be completing the job. The SOP contains detailed, step by step instructions and includes everything from cutting a piece of pipe to completing “critical steps.” Critical steps are larger tasks that, once completed, could affect the operation of our distribution system.

    Before any critical step is started, our employees and contractors are required to call our Gas Control Center before starting the work. 

    Our Crews, Gas Control Center and Operations Supervisors practice exceptional communication skills. With open lines of communications, we ensure everyone is aware of what is going on and can respond to any given situation safely and effectively.

  • In order to work on our natural gas distribution system, employees must follow stringent training and qualifications measures.

  • On all of our meter stations, we have devices called “telemeters” installed. Telemeters measure characteristics from our gas system such as pressure and flow. The information is communicated to our Gas Control Department. If anything were to go wrong with our gas system, the telemeters would pinpoint the exact location of the problem, allowing us to resolve it quickly.

What You Can Do

 


  • Carbon monoxide, or CO, is a normal by-product of fuel combustion, but high levels of it indoors can be dangerous to your health. Typical heating fuels (oil, coal, wood, gasoline, kerosene, diesel fuel, or natural gas) can create carbon monoxide. Carbon monoxide has no odor, color or taste, but can cause serious health issues. Take steps to make sure your home is protected.

  • As the customer of record, you or the property owner are responsible for customer-owned gas lines that begin at the outlet of the gas meter and extend — either above or below ground — to natural gas-burning appliances. Make sure your pipes are getting the attention they need.

  • Planting a tree? Installing a fence? Planning a home improvement? Call 811.

    Did you know it’s the law to make this call? Electric power lines, natural gas pipelines, water pipes, communications lines and other utility services can be within a few feet of the ground’s surface. Not knowing where these lines are can result in personal injury, property damage and neighborhood service interruptions. Even a small dent or a scrape can cause damage, resulting in a leak or service-wide disruptions.

  • Gas appliances are safe and efficient. Like all appliances, certain safety precautions should be followed. Make sure your family is safe by following these guidelines.

  • Adding gas appliances or equipment increases gas pressure and requires a safety check. Contact Liberty Utilities to determine if your gas service and/or meter, has the capacity to handle the additional gas load.

  • Maintaining chimneys and flue pipes is an important safety requirement. Liberty Utilities urges you to have a licensed heating contractor periodically inspect your chimneys and flue pipes for safe operation.
