What is ex-filtration in relation to sewage systems?

Ex-filtration refers specifically to the process where sewage or wastewater escapes from the pipes of a sewage system through either joints, cracks, or voids. This is a significant concern in collection systems because it can lead to contamination of the surrounding environment, including groundwater and surface water. Ex-filtration may also compromise the system's efficiency and increase operational costs due to the loss of sewage that should be transported for treatment.

Understanding ex-filtration is important for maintaining the integrity of sewage systems and ensuring compliance with environmental health standards. Regular inspections and maintenance are crucial to identify and repair any points of leakage, thereby preventing ex-filtration from occurring. This concept is fundamental in establishing strategies for the durability and reliability of sewage infrastructure.
