More than 70 million American consumers rely on natural gas to heat their water, cook their food, dry their clothing, heat their homes, and fuel both commerce and industry. Natural gas is a safe, economical, efficient, clean-burning, non-polluting, and dependable source of energy when used correctly in equipment that is properly installed and maintained.

Unitil operates 86 miles of natural gas transmission pipeline and nearly 1250 miles of distribution pipeline in Massachusetts, New Hampshire and Maine.  The system lies safely out of view, quietly carrying clean-burning natural gas throughout New England.  Our goal is to operate an energy delivery system that runs safely and reliably, so people can count on the natural gas being there when they need it.  Here is a link outlining Unitil's plan and activities to ensure the safety of our pipeline system. It is a summary of our Integrity Management Plan.

Like all sources of energy, natural gas should be used wisely and treated with respect.  Take a few moments to review these pages which contain information about the safe use of natural gas, to help ensure that you and your family enjoy all the benefits natural gas has to offer.
