What is the Lowell Area Gas Modernization Project?

National Grid is standardizing the gas main between Lowell and Tewksbury to enhance the overall safety and reliability of the existing gas distribution network through inline inspection technology, also referred to as a “Smart Pig”. The Smart Pig Technology utilizes sensors which are capable of detecting changes in pipe wall thickness and internal and external anomalies, such as third party damages or corrosion.

The use of this technology will eliminate the need to conduct ongoing excavations along the line to conduct pipeline inspections. Construction is expected to begin in Fall 2019, with an expected completion in early Spring 2021. Construction methods and schedules will vary along the route.
