What is a sewage well?
A manhole is one of the main elements of a modern drainage system. Many people associate this term mainly with the manholes visible on city roads and sidewalks. However, manholes are also used in private sewage pipe systems.
An inspection chamber allows access to underground pipelines, e.g. for cleaning and repairing them.
In our offer you will find:
Types of sewage wells
Inspection manholes are divided into:
- manhole – supplied with a ladder or stairs that allow you to go down to the canal in person;
- non-entrance – equipped with an opening through which it is possible to carry out inspection using a special camera;
- connecting – serving as a link between two channels;
- pass-through – installed, among others, on long, straight sections of the installation and at channel bends.
Each inspection chamber may also differ in material. Today, modern plastics (e.g. polypropylene) are most often used in their production, but traditional concrete rings are still very popular.
Sewer manholes - application
The key task of an inspection chamber is to provide easy and quick access to drainage pipes. This allows for periodic maintenance of the sewage system, as well as ongoing repair of pipelines.
Wells can also have their specific applications. For example, a water meter well allows you to observe the flow and take accurate water measurements.
Regardless of the purposes a manhole must fulfill, it must meet a number of legal and technical requirements. All the manholes available in our range have undergone rigorous quality tests - so you have a guarantee that they will not disappoint you.
