What is a drainage manhole?

A drainage manhole is an underground access point used in drainage systems to facilitate maintenance and inspection of sewer lines and stormwater management systems. It allows for the removal of blockages, cleaning of pipes, and monitoring of flow. Typically constructed from materials like concrete or brick, manholes are strategically placed at intervals along drainage systems to ensure efficient operation and accessibility. They often feature a removable cover to provide entry for maintenance personnel and equipment.
