Executive summary

  • A Water Safety Plan turns water quality control into a preventive risk-management cycle.
  • The plan should connect hazards, control measures, monitoring points, indicators, corrective actions and documented review.
  • Microbiological indicators should be selected according to the hazard, matrix, treatment stage and decision required.
  • Digital traceability helps maintain evidence across sampling, testing, interpretation, reporting and follow-up.
  • AquaVerify supports the program with product families and Cloud workflows that connect operational control with documented evidence.

Technical context

Risk first, testing second

A Water Safety Plan begins with the water system and its hazards. Testing is essential, but it is strongest when it is tied to a defined risk, control measure and decision path.

Indicators as decision tools

E. coli, enterococci, coliphages and other indicators answer different questions. The plan should explain why each indicator is used, what action follows and how results are reviewed.

Making the plan auditable

A plan becomes auditable when it links sampling points, events, results, reviews and corrective actions. Digital traceability reduces the risk that evidence is scattered across spreadsheets and email threads.

FAQ

Is a Water Safety Plan only for municipalities?

No. The same risk-based logic can support utilities, facilities, industry, agriculture and food operations.

Which indicators belong in a WSP?

The indicators depend on hazards, matrix, treatment and decision needs. Bacterial indicators and coliphages can play different roles.

How does AquaVerify Cloud fit?

It helps connect sampling, results, review, corrective actions and reports in one evidence flow.
