In this session, we will discuss the potential use of methane data collected by a mobile ALD system to inform and refine pipe replacement prioritization decisions. Conventional Distribution Integrity Risk (DIMP) models are only as good as the historical data that informs them. Plus, risk calculations often give disproportionate weight to just a handful of key threats and sub-threats, regardless of the pipe’s conditions, actual leak density and associated emissions. Picarro has demonstrated at several utilities that is possible and advantageous to combine real-time methane data with existing DIMP models used for pipe replacement prioritization in order to improve the pipe replacement selections yielding 2 to 3 times more leaks removed. This results in a significant reduction in O&M expense since leaks removed by pipe replacement are not individually found and repaired, and additionally, it reduces odor calls, risk, and emissions.

Participants will hear firsthand from Picarro and utility experts describing:

• How to practically implement a Picarro-informed pipe replacement optimization program
• Anticipated benefits and ROI
• Lessons learned along the way
