Distribution Integrity Management Program (DIMP)

Montana-Dakota Utilities Co. routinely evaluates and prioritizes risks to validate the integrity of the distribution gas pipelines so they continue to be operated in a safe and responsible manner without interruptions.

In order to keep up with state and federal laws, MDU has identified sections of pipe for replacement based on physical and operation & maintenance components.

These type of replacement projects are not new, since 2020 MDU has successfully replaced sections of main and services in the following cities.
