Full Description

Protection of water quality in the distribution system forms the final barrier in the multi-barrierapproach to providing safe drinking water. Drinking water systems are beginning to take moreproactive steps towards water quality management in the distribution system. One tool with thepotential to assist drinking water systems with maintaining that final barrier is the HazardAnalysis and Critical Control Points system (HACCP). HACCP provides a framework forassessing and managing risks to prevent adverse outcomes. The intent of the HACCP system isto focus system control at critical points throughout a process, thereby preventing hazards fromoccurring, or reducing hazards to an acceptable level. HACCP is carried out in 12 steps: fivepreliminary steps and seven principles. A key feature of the HACCP approach is itsmultidisciplinary approach. The HACCP team is assembled to include personnel fromoperations, maintenance, the laboratory, engineering, management and other utility personnelinvolved with water quality management (i.e. cross connection control, inspection staff). As aresult of the team's diversity, working through the HACCP process will initiate dialog betweenstaff that normally don't discuss their responsibilities and their water quality impacts with eachother. It also provides a forum for staff to discuss their concerns with how specific operationalactivities or utility policies may impact water quality in the distribution system. Two utilities arecurrently piloting the HACCP process in their distribution system as part of AwwaRF Project#2856. Includes 2 references, figures.
