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.
A gulley trap will have a water seal and connects each drainage line from the building to the first manhole. One manhole will have one or many drainage line inlets and one outlet that is used to carry drainage water to long distance for disposal.

An invert manhole refers to the lowest point inside a manhole where wastewater or stormwater flows. It is designed to facilitate the smooth movement of water from one pipe to another, ensuring proper drainage and preventing blockages. The invert level is critical for maintaining the correct slope and flow dynamics in a drainage system. Properly designed inverts help to minimize the risk of flooding and ensure efficient wastewater management.
The Manhole happened in 1988.

The Manhole was created in 1988.
A terminating manhole is a type of access point in a drainage or sewer system where the pipeline ends, rather than connecting to another pipe. It allows for maintenance and inspection of the system, ensuring proper flow and preventing blockages. These manholes are typically designed to facilitate the removal of debris and provide access for cleaning or repairs.
Because it is a hole in a street meant for workmen to climb down to check the sewers. A hole for a man is a manhole.
If they were rectangular they could fall down the manhole.

Rim, on a manhole, is the elevation of the top of the cover on the manhole. In a roadway the rim will at be final grade, in grass they can be sumped, flush or stick up.
The manhole is at Main Street by the Muesuem.
