Sewer pipe cleaning operations are carried out throughout the year, though they are more frequently done in summer and fall. These are times when the rain tends to cause dirt and debris which clogs up the sewage systems. Professionals use two systems of cleaning – jetting and vacuuming.

Jetting is a process in which a high-pressure water hose with a sewer-jetting nozzle is pushed into the dirty pipeline. High-pressure water is released from the sewer jet truck to dislodge all of the dirt and flush it away into a gully hole. As the dirt is removed, the nozzle continues to move deeper into the sewer.

Sewer cleaners also use vacuuming through which all of the dirt is extracted with a vacuuming system. All the solids and water removed this way are then disposed into a sludge tank.
