Exfiltration

Exfiltration refers to the leakage of wastewater into soil and groundwater through faulty joints, damaged pipes, around manholes, etc.

The problem is difficult to discover, and there is a risk of contamination of the environment, such groundwater, lakes and ponds.

Advanced controls can sometimes measure a pressure loss in the pipes downstream from the leakage.
