What is the function of manholes in a collections system?

The function of manholes in a collections system is primarily to provide access for maintenance and inspection of sewer lines. They serve as access points that allow operators and maintenance personnel to enter the sewer system safely to conduct inspections, identify blockages, perform repairs, and ensure the system is functioning properly. This access is crucial for maintaining the integrity of the collection system and preventing potential issues such as overflows or backups.

Manholes are also strategically placed throughout the sewer network to facilitate the monitoring and upkeep of the system, allowing for more efficient and effective management of sewage flow. By providing a means to reach different parts of the sewer system without extensive excavation, manholes play an essential role in routine maintenance activities, contributing to the long-term reliability and safety of the wastewater collection infrastructure.
