About This Checklist
Water is a critical utility in pharmaceutical manufacturing, used as an ingredient, processing aid, and cleaning agent. This Water System Validation Audit Checklist is designed to comprehensively evaluate the validation and ongoing control of pharmaceutical water systems, including Purified Water (PW) and Water for Injection (WFI) systems. By systematically assessing system design, installation, operation, maintenance, monitoring, and quality control processes, this checklist helps ensure the consistent production of water that meets pharmacopoeial and regulatory standards. Regular use of this checklist supports compliance with Good Manufacturing Practices (GMP), enhances product quality, and minimizes risks associated with water-borne contamination in pharmaceutical products.

The checklist covers water source assessment, pretreatment systems, purification technologies (e.g., reverse osmosis, distillation), storage and distribution systems, sanitization procedures, and monitoring programs for chemical and microbiological quality.
Comprehensive audits should be conducted annually, with more frequent assessments of critical parameters and periodic review of trending data. Revalidation should be performed after any significant changes to the system.
The audit team should include water system specialists, quality assurance personnel, microbiologists, engineers familiar with water purification technologies, and validation experts.
The checklist includes specific sections for different water grades (e.g., Purified Water, Water for Injection), addressing the unique requirements and critical quality attributes for each type.
Yes, the checklist is designed to be applicable to both new system qualifications and ongoing validation of existing systems, with sections addressing initial validation, periodic review, and change control processes.
