Most large cities today have dedicated waste treatment facilities according to Αποφράξεις Πειραιάς. Through a complex drainage system connected to the houses and generally all the buildings, to other pipes and finally to the special sewage treatment facilities.
The waste is led there, where the water is partially purified and then it is emptied into streams, the sea or in other sewage systems. Learn information and facts about the sewer pipe, this invisible daily carrier of our sewage and filth.
It is good to have a familiarity with the mechanisms that “run” above, below or on the side of your house in order to either attempt blockages, interventions in the ducts yourself or know when you need to call a professional.
In the past, sewer pipes were made of lead because it is a very soft metal that could be easily worked. Other materials used in ancient times for the construction of pipes and channels were clay, wood and stone, while about 3 centuries ago the pipes of the time consisted of hollow pieces of wood covered with steel.
In the newer era, copper took the lead. Thus, pipes were made mainly of soft copper and then of rigid copper, reaching the shape and texture we know them today. At the same time, several decades ago, the use of lead was completely abandoned due to the growing concern about the risks of poisoning from this material.
Modern water supply and drainage systems in buildings consist of a network of pipes made of copper, brass, plastic (Polyethylene, Polypropylene, PVC) or other non-toxic materials.
Widely used for the production of sewer pipes, PVC is light, strong and has little thermal variation. PVC pipe systems usually have a socket and grommet connection system for very quick installation.
In sewer systems PE has many advantages for systems under pressure or where an out-of-pit installation is required. The combination of impact resistance and flexibility of the tubes is unbeatable.
With high tensile, chemical and temperature resistance, polypropylene pipes are ideal for sewage systems. They come with a custom socket and rubber grommet for quick and easy installation.
Drainage pipe structure
When we say pipes, we mean a hollow rigid, straight structure. There are the pipes and ducts. Pipes are usually made by casting or welding the materials that make it up.
The pipe takes its shape through a pressure-based process called extrusion. Pipe has thicker walls and can be bolted or welded to other pipes, while conduit has thinner walls and is joined to pipes or other pipes in more complex ways (welding, compression fitting, crimping). It is precisely in these straight sections that clogs are usually observed and material accumulations are created.
Choice of obstruction method
Choosing the appropriate occlusion method depends on where the blockage is located. There are tools used for blockages, most of which are inserted into pipes or ducts.
Therefore, knowing the tool that will enter a duct that has thin walls will guide us in choosing the appropriate plugging tool. For example a tool that will not damage the walls of a small diameter pipe.
Also, the selection of the appropriate sprinkler head for a particular pipe depending on its age and current condition.
Drainage systems should normally function as if they did not exist. The ideal situation is to carry waste water out of buildings, quietly, creating a comfortable and healthy home and business environment. The smooth operation of a sewer network begins with its design and construction. Three important elements for optimal use and longevity of your drainage system are.
Correct architecture, structure and installation of the drainage system.
Suitable diameter of pipes/ducts according to the range of use and the volume of the building.
Quality and durability of the materials from which the pipes are made so that there is the required resistance to toxic materials, tree roots and natural damages.
