Overview of Electrical Leak Location (ELL) Methods and Their Application

All geomembrane-lined containment facilities should be tested for leaks before going into service. Early detection of leaks allows for swift and effective repair pre-service, protecting the engineer, contractor, owner and in many cases the environment. There are a variety of different methods available for electrical leak location. Choosing and specifying the most appropriate method requires an understanding of the technologies available: their benefits and limitations. In many applications an ELL method must be specified in the design phase, before construction starts, to ensure a successful test.

This presentation identifies the various common ELL technologies and identifies criteria which should be considered when specifying electrical leak location (ELL) methodology. Earn 1 PDH at the conclusion of the first webinar.
