When talking about a building or property’s sanitation, it refers to the collection, channeling, and distribution of wastewater and rainwater until it reaches the sewer network. The manholes are deposits that play, in this case, an essential role. The purpose of the manholes is an affordable way to separate unwanted waste from the water that passes through it and direct it to where it is desired.
If a manhole becomes clogged, it can cause bad odors, overflows, and serious damage to the apartment or condo. Do you know how to identify the types and purposes of the different manholes? Learn to differentiate them to prevent unwanted jams.
Types Of Manholes And Their Functions
- Passage Boxes:
They are located at intermediate points in the sanitation network and where changes of network addresses occur. They are used to connect two conduits that are generally at a difficult angle to find standard connections. These manholes are registrable, that is to say, that the upper cover can be opened to be verified so that when there are traffic jams, they are the first to be used.
- Siphon Boxes:
It is a tank with a recordable siphon or gooseneck, and its primary purpose is to prevent the passage of air and bad odors, allowing only the passage of liquids. Maintenance corresponds to the apartment or condominium owner, and it is recommended that it be done regularly.
- Grease Separating Boxes:
This deposit favors the industrial sector, and they are registrable because they retain fats and oils due to their density, allowing only the water to pass into the public network. The maintenance must be periodic, according to its production, and corresponds to the owner of the factory. They are usually placed at the end of the sanitation network.
- Manholes At The Foot Of Downspouts:
They are mainly used when rainwater is channeled. It is recommended that in its construction, it can be registered, taking into account that this water goes to a different tank; otherwise, it can be done by connecting directly to the sewage without registration. It should not be a siphon type.
- Sump Manholes:
They are the ones that have a kind of grid in the upper part frequently used in the pavement to channel rainwater, facilitate drainage, and avoid accidents. Its maintenance must be up to date, especially when the rainy periods begin. In general, its maintenance depends on the local authorities.
