Advanced Leak Detection

Enhancing safety and reducing methane emissions

You may see a new vehicle on the roads – one with unexpected safety features.

In our journey to continually reduce risk, we have partnered with Picarro, an industry leader in analytics-driven methane detection, to deploy an advanced mobile methane detection unit across our service territory.

The Picarro vehicle may be coming to a neighborhood near you and provides us with another tool to help identify potential leaks and to better measure methane emission reduction.

Take a moment to think about your home and your neighborhood, your family, neighbors and friends. We think about them every day. We're proud to be part of your community too, providing the natural gas service homes and businesses depend on each day. 

We care about your safety and about our environment, which is why we monitor for potential gas leaks regularly through continuous inspections, monitoring and upgrades. We're focused on maintaining a safe natural gas system year-round. And we're excited to announce the latest addition of a revolutionary innovation to our array of existing natural gas detecting tools that's faster, more advanced and more sensitive than anything available before. Meet the Picarro Surveyor. This vehicle doubles as a cutting-edge lab for the detection of natural gas leaks and much more. Created by Picarro, the world's leading provider of advanced mobile leak detection, the vehicle and Picarro's innovative technology, measures ultra-trace methane concentrations in the air and is up to 1000 times more sensitive than traditional methods, and maps them with high resolution GPS, which allows us to gather more information and analyze it so we can quickly assess and proactively respond to a potential leak should we come across one. 

The surveyor vehicle does it all while on the move quickly and efficiently. All of this leads to a range of benefits, including reduced methane emissions from our underground gas lines, prompt response to emergency conditions, enhanced ability to prioritize maintenance work, and much more. 

So, when you think about the safety journey NiSource is on, you think about investing in technology that enhances public safety, enhances our ability to serve our customers and keep our employees safe. Picarro Surveyor will give us information to help us support operations in ways that we have never seen before. 

We invested in the Picarro surveyor to continue to keep your homes neighbors and communities safe and comfortable.

How does the Picarro vehicle work?

The vehicle is equipped with advanced sensing equipment that processes the content of the air as the vehicle drives down the street. The data collected will be thoroughly analyzed. If a potential gas leak is detected, we will follow our existing processes to investigate, grade, and repair the leak or replace the pipe.
