This online training course provides a summary of compendial water systems from generation through storage and distribution. Feed water impurities and their impact on system design, operation, and maintenance will be discussed. The validation process is discussed from Validation Master Plan, URS, FRS, FMEA, IQ/OQ/PQ through long-term monitoring throughout the training course. Numerous case histories and “hands on” observations will be discussed to demonstrate proper design, operation, qualification, monitoring, and proactive preventative maintenance. A section of the training course will discuss non-distillation based Bulk Water for Injection Systems. The training course content will be valuable to any individuals interfacing with bulk compendial water systems from design, engineering, operation, manufacturing, Quality Assurance, compliance, maintenance, monitoring, and excursion evaluation.
