Checklist 3: Reservoir and Storage Hygiene

1. Access Protection

☐ Reservoir access secured

Access hatches, doors, and inspection openings should be protected against unauthorized entry and accidental contamination.

2. Ventilation Protection

☐ Hygienic ventilation installed

Ventilation openings should prevent the entry of insects, birds, rodents, dust, and other contaminants while allowing proper air exchange.

3. Structural Integrity

☐ Reservoir structure inspected

Walls, roofs, floors, and seals should be regularly inspected for damage, leaks, or other defects that could compromise water quality.

4. Cleaning Program

☐ Reservoir cleaning scheduled

Reservoirs should be inspected and cleaned periodically to remove sediments, deposits, and potential biological growth.

5. Water Retention Time

☐ Water retention time monitored

Excessive storage times may negatively affect water quality. Water should be exchanged regularly to avoid stagnation.

6. Hydraulic Performance

☐ Proper water circulation verified

Reservoir design and operation should promote continuous water movement and prevent dead zones where water may stagnate.

7. Inspection Records

☐ Inspection and maintenance activities documented

All inspections, cleaning activities, repairs, and operational observations should be recorded and retained.

8. Emergency Preparedness

☐ Reservoir contamination procedures available

Procedures should be established to isolate, inspect, clean, and return reservoirs to service following a contamination event or suspected hygiene incident.
