Executive summary
Directive (EU) 2020/2184 reinforces risk-based thinking for water intended for human consumption. In Spain, RD 3/2023 develops a technical-sanitary framework that affects operators, administrations, laboratories and organizations involved in control, supply or verification of drinking water.
Somatic coliphages can be useful when the program needs an operational viral-type indicator for raw water, treatment assessment or advanced surveillance. This whitepaper helps translate regulatory context into operational questions: what to measure, where to measure, how to document it and how to connect results with traceable evidence.

1. From regulation to risk-based control
Modern drinking-water control is not limited to isolated parameters. It considers catchment, treatment, storage, distribution, critical points, history, incidents, communication and corrective measures.
A result should answer not only “what was detected”, but also where the sample came from, why the point is in the program, which method was used, which lot and operator were involved, how review happened and what action follows if a deviation is identified.
2. Where somatic coliphages fit
Somatic coliphages can provide additional information where a viral-type microbiological signal is relevant. They are most useful as part of a program, with defined sampling point, method, volume, controls, interpretation criteria, frequency and traceability.
3. Comparison table
| Operational question | Evidence to prepare | Risk if missing | AquaVerify support |
|---|---|---|---|
| Why is this point sampled? | Sampling-plan and risk justification | Results without context | Point, location, program and customer record |
| Which indicator is measured? | Parameter, method, matrix and criterion | Ambiguous interpretation | Product, method, lot and documented workflow |
| Who performed and reviewed it? | Operator, date, controls and review | Weak chain of custody | AquaVerify Cloud traceability |
| How is the result communicated? | CoA, observations and recommendations | Fragmented communication | Technical report and customer portal |
| What happens after deviation? | Corrective action and closure evidence | Weak audit trail | Status, history and documentation |
4. Implementation checklist
- ✓ Identify whether the point is raw water, treatment, distribution or final point.
- ✓ Justify why somatic coliphages are included.
- ✓ Verify applicable references: EU Directive, national rules, ISO 10705-2.
- ✓ Define frequency and technical review criteria.
- ✓ Document method, volume, host strain, controls and lot.
- ✓ Associate result with sample, point, customer, operator and report.
- ✓ Define escalation rules for deviations.
- ✓ Maintain reviewable evidence for audits or authorities.
