First - types of obstruction and its causes
- The pipes are clogged due to the roots of the trees on the sewage network pipes at the connections.
As the roots of plants and trees can enter the tubes in the network either by means of connections or through capillary cracks in the tube body caused by these roots.

- Neglect and misconduct by some citizens towards the network, as it is used by some citizens to dispose of all their waste such as ((peel of vegetables, fruits, stones ...))

- In some projects that are implemented by the contractors and because of the lack or recklessness of the engineers supervising the contractors' work, some contractors may resort to dumping the remnants of the works that he undertook.
Such as .... paving roads ....... telephone line fossils ....... electrical line fossils ...... various other works .....
As dumping some of the waste from these works or projects in the manholes will definitely lead to a blockage in these rooms and also lead to the clogging of the sewage pipes in the network by the deposition of these wastes in them.

Drainage of water containing high levels of fat, grease, and suspended material in the sewage network pipes. This water causes these fats and greases to stick to the floor and wall of the tubes, resulting in a blockage of the tubes.

- Negligence by those responsible for monitoring the safety of the network and its equipment for periodic monitoring of one of the network equipment, which are the oil covers of the manholes where it results from this negligence. Inspection. This will result in some animals entering the pipeline network and entering large dirt as a result of drifting in with water into the network. Like tree roots, big stones, plastic parts ... etc

- Blockage due to improper implementation of the network, during the laying of pipes. Some cement materials enter the pipes inside during the permitting or fixing of pipes with each other, or during backfilling operations. Some of the backfill materials enter the network tubes.

As well as a blockage caused by randomness in the periodic maintenance of the network and leaving dirt resulting from maintenance inside the pipes. There are many reasons for the blockage of pipes in the sewage network and we mentioned the most important and most common reasons in our society, unfortunately.
After studying the most important causes of blockage of the sewage network pipes, cleaning methods must be developed that suit each type of blockage. In order not to face any problem that constitutes an obstacle to the cleaning process, it is necessary to know the nature of the area or street under which the tube that has been clogged to know the time required to carry out the cleaning process. For example, the street may be a major hub in the region, and there is a crowd of cars. It should be known how long the piping network must be cleaned.

Second - environmental hazards that may occur as a result of clogging the network tubes
Blockage of the network pipes results in damage to the foundations of roads and buildings and cracks caused by sewage leaks.
Pollution of groundwater, and the public supply network water may be polluted when there are defects in the supply network
The accumulation of dirt and sediments in the sewer pipes causes weak inclination or falls. In the presence of sulfate electrolytes, it can lead to anaerobic degradation that results in hydrogen sulfur gas which over time corrodes the top surface of the concrete tubes.

The cleaning process of the sewage pipe is a preventive maintenance of the sewage pipe. It is a network inspection program on a regular basis.
This periodic inspection is at least once a year to four times in areas where the slopes of the pipes are low.
The following picture shows us one of the leakage products in the sewage network pipes resulting from the blockage in one of the network pipes.
Landing in the street as a result of leakage of sewage caused by blockage of one of the pipes
Flooding and runoff of sewage in the streets as a result of clogging of the sewage pipes

Third - Methods of cleaning sewage pipes,
past and present, in a brief scientific comparison
First - old ways of cleaning sewage pipes

- Washing the sewage pipes by blocking the pipe to be cleaned through a room
Inspections are at the beginning of the tube.

This method is done by plugging the tube through the inspection pit by means of a metal plug, or any plug of any other material. Then the manhole is filled with water and can be clean water. Then the dam is removed suddenly, forming a sweeping wave of water sweeping away the sediments that have not yet solidified and transported with it through the network.

Washing by inserting a metal ball made of superimposed circular metal sheets into the net

In this method, the water is stored behind the metal ball, and the water stored behind the ball is created
Within the tube causing the sludge to loose and move. Where ordinary metal balls can be used in this process, and a special device or machine is placed in this way in order to catch and remove the ball, and the metal ball can be attached to a cable and then let the ball roll over into the tube until its end. Then the ball is pulled using the cable to remove it from the same inspection room and this movement causes Additional failure of sediment within the tube.

Manual Methods
These methods are used for pipes with large diameters, which workers can access for manual cleaning via manual equipment for these operations.
Where workers cut down tree roots from pipes and break and remove hardened sediments, in these ways it is necessary to exercise great caution and adhere to safety conditions on cleaning workers to prevent pollution from being in direct contact with wastewater. Among these conditions to be followed for safety:
Rubber boots
- Rubber gloves
Ensure that there are no toxic gases such as CO2 - H2S and oxygen concentration before entering the network tubes....
