In the event of damage in a sewer system, rehabilitation becomes necessary in order to restore its functionality and extend its useful life. This is to prevent both extraneous water from infiltrating and placing additional load on the sewer system and sewage from exfiltrating and contaminating the groundwater and the soil.
