Water Supply Cross-Connection Control
This online engineering PDH course describes some of the basic principles of plumbing cross connections. The document provides multiple examples of cross-connection illustrations and provides a discussion of the cause of flow reversal and suggested corrective actions. In addition there is a discussion of the various cross-connection prevention methods and devices that can be used to prevent backflow.
Plumbing cross-connections, which are defined as actual or potential connections between a potable and non-potable water supply, constitute a serious public health hazard. There are numerous, well documented cases where cross-connections have been responsible for contamination of drinking water, and have resulted in the spread of disease. The problem is a dynamic one, because piping systems are continually being installed, altered, or extended. Control of cross-connections is possible, but only through thorough knowledge and vigilance. Education is essential, for even those who are experienced in piping installations fail to recognize cross-connection possibilities and dangers.
This 4 PDH online course is applicable to engineers who work with plumbing systems where cross connection between potable and non-potable systems is a concern.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Public health significance of cross-connections
- Theory of backflow and backsiphonage
- Methods and devices for the prevention of backflow and backsiphonage
- Testing procedures for backflow preventers
- Administration of a cross-connection control program
- Cross-connection control ordinance provisions
In this professional engineering CEU course, you need to review the material contained in the Cross-Connection Control Manual Environmental Protection Agency, EPA 816-R-03-002, February 2003.
