What is one reason to measure the distance in a sewer maintenance operation?

Measuring the distance in a sewer maintenance operation is crucial for understanding the layout and location of sewer lines, which directly relates to identifying potential hazards. This knowledge helps in detecting issues like blockages, structural failures, or locations that might be prone to flooding or other environmental risks. Knowing the precise location of potential hazards enables maintenance crews to take proactive measures, ensuring the safety of workers and minimizing service disruptions. Accurate distance measurements facilitate planning, navigation, and the effective deployment of resources to manage any problems that may arise in the sewer system.
