Erosion
Definition - What does Erosion mean?
Erosion of sewer pipes can be defined as the process by which the internal surface of a pipe deteriorates due to the abrasive action of moving solid particles and gas bubbles present in the sewage flow. These particles are suspended in the flow and the problem can be aggravated if corrosion is already present in the pipe. This can lead to a loss of strength of the pipeline and can lead to failure of the system.
Trenchless rehabilitation methods can be used to rectify problems caused by erosion.
Trenchlesspedia explains Erosion
Erosion is more evident in combined sewer systems and in force mains where there is a possibility of penetration of solid particles into the sewage system. Surface and stormwater runoff enters into these systems and often carry solid particles with them. When the flow velocity in the sewer system exceeds a certain limit, wear and tear can occur due to erosion and abrasion. The flow of sewage should not exceed 3.6 m/sec in high grit sewage handing systems and 5.4 m/sec in low grit sewage handling systems.
Trenchless rehabilitation methods can help pinpoint problem areas affected by erosion, and appropriate methods can be used to rectify the problem. Upgrading combined sewer systems to separate systems can also help prevent problems caused by abrasive particles entering the sewer system.
