In a Water Vulnerability Assessment (WVA), the three phases are pre-assessment, information gathering, and information processing.

Starting with pre-assessment, you set the stage by defining the scope and objectives, determining system boundaries (like source water, treatment, and distribution), and outlining how the assessment will be conducted. This phase establishes what data you’ll need and who will be involved, so everyone understands the purpose and limits of the evaluation.

Next comes information gathering. This is the data-collection phase where you pull in details about the water system—source water quality, treatment processes, distribution network characteristics, past incidents, monitoring results, and potential vulnerability indicators such as cross-connections or storage issues. The goal is to assemble a complete picture of what could affect safety and reliability.

The final phase, information processing, uses the collected data to analyze and interpret vulnerabilities. You synthesize the information, assess risk, prioritize actions, and develop recommendations and a final report. This is where raw data becomes actionable insights for protecting drinking water.

The other options reflect general project-management language (planning, execution, review or initiation, planning, closure) rather than the data-driven, vulnerability-focused sequence specific to WVA, so they don’t align with the typical WVA workflow.
