Internal Corrosion Control and Lead Service Line Replacement DVD
Following the events in Flint, Michigan, lead in plumbing and service lines has been the focus of media and industry insiders alike. To prevent lead and other contaminants from entering drinking water, there are two main parts of the equation: understanding the proper techniques for controlling corrosion and developing and executing a plan for full lead service line replacement. This video covers both topics extensively, along with highlighting key components from AWWA's Manual, M58 Internal Corrosion Control in Water Distribution Systems.
Corrosion control treatment options covered include: pH and alkalinity adjustment and the use of corrosion control inhibitors. A case of successful lead service line management from Lansing, Michigan is featured. The utility has come up with a way to standardize its line replacement process by minimizing excavation, and pulling out the old service line, while simultaneously pulling a new copper line in.
