Basic Guide About Manholes

 

What is a Manhole?

The manholes can be defined as vertical access points from the ground surface to a sewer or stormwater line, typically at a junction, allowing maintenance, cleaning, inspection, and repairs. There are different types of manholes that might be necessary for various places, and their design may vary depending on the area of application. 

What is the purpose of a manhole?

The true function of a manhole is an alien concept to some people, and many miss the point when talking about the functionality of a manhole. The manholes are designed to enable repairs and various sewage maintenance works. They are also essential for underground cleaning and connections that are important for a seamless sewage system. They are important for gases to escape providing an area of ventilation and make the sewage line secured. They are also necessary to guide the stormwater to find the way through the connection to avoid clogging at any point.

Different Types of Manholes

Normal Manholes

These manholes are characteristically five feet deep. The normal manholes are commonly located in the sewer and are equipped with a huge tank manhole cover. The shape of the covers might vary depending on the design. They can either be rectangular or circular.

Deep Manholes

The manholes that are a bit deeper than five feet are classified as deep manholes. They are often equipped with a dedicated area for entrance to enable repairs and connections. These manholes are covered with a heavy tank manhole cover, which is typically circular in shape.

Shallow Manholes

These manholes are not as deep as the other manholes and are often only two or three feet deep. The location of shallow manholes is typically at the start of the sewer, and their usual placement is in areas that are not heavily trafficked.
