Checklist 2: Water Treatment and Disinfection

1. Treatment Objectives

☐ Treatment objectives defined

The required treatment processes should be based on raw water quality, potential contamination risks, and drinking water quality targets.

2. Treatment Processes

☐ Appropriate treatment processes installed

Suitable treatment technologies such as filtration, activated carbon treatment, membrane filtration, UV disinfection, or chlorination should be selected according to the identified risks.

3. Disinfection Barrier

☐ Disinfection system available

A reliable disinfection process helps inactivate harmful microorganisms and provides an important barrier against waterborne diseases.

4. Operational Monitoring

☐ Treatment performance monitored

Key operational parameters should be measured regularly to verify that treatment systems are functioning as intended.

5. Equipment Maintenance

☐ Treatment equipment maintained

Filters, pumps, UV systems, dosing equipment, and other treatment components should be inspected and maintained according to established schedules.

6. Alarm and Failure Detection

☐ Alarm systems installed

Critical treatment processes should be equipped with alarms to provide early warning of equipment failures or abnormal operating conditions.

7. Documentation

☐ Treatment records maintained

Operational data, maintenance activities, inspections, and water quality results should be documented and retained for future reference.

8. Operator Competence

☐ Operators trained in treatment processes

Personnel should understand the function, limitations, and operational requirements of all treatment and disinfection systems used within the facility.
