What is the maximum distance allowed between manholes?

The maximum distance allowed between manholes is typically set at 500 feet. This standard is implemented to ensure accessibility for maintenance and inspection of underground utilities. Manholes serve as access points to utility lines, which may need to be cleaned, repaired, or replaced over time. By limiting the distance between these access points, it becomes easier for technicians to reach various segments of the utility infrastructure efficiently.

Manholes that are too far apart can complicate repairs and increase the time required for maintenance activities, possibly leading to higher operational costs and lengthy disruptions. Thus, establishing a maximum distance of 500 feet ensures both practicality and safety in managing utility systems.
