Objective: Review fundamental concepts of Cross-Connection Control (backflow prevention), at your Water System Site, so that your System Operator can develop a 'Hands On' understanding of what is involved in protecting a Potable Water System against uncontrolled plumbing cross-connections between process waters and/or other potential sources of contamination.
NOTE: A two-hour, Power-Point presentation of Cross-Connection Control concepts can be provided in lieu of (or as supplementation to) the field training.
