Sanitary Inspection (Practical Exercise)

Session Objectives

· To demonstrate the need for sanitary inspection in the management of water supplies.

· To demonstrate the value of sanitary inspection as a means of promoting improvements in water supply.

· To describe the sanitary inspection techniques and the development of inspection forms based on risk scoring schemes.

Outline

1. Ask the participants, in small groups, to study the photographs and identify any sanitary risks present.

2. Ask the groups to rank the systems. Make sure they do this independently and compare the findings of different groups.

3. Use these findings and the attached overheads to describe the key problems often faced with sanitary inspection.

4. Using the overheads, highlight that sanitary inspection data may be classified into broad groups indicating different levels of risk and that such data may also be used to rank systems on the basis of risk.

Participant Notes

1. Study the photographs carefully and note all the potential sanitary risks that you can identify.

2. Rank the water supplies on the basis of greatest risk, with the supply at greatest risk first.

3. Briefly highlight some key common factors which should always be assessed when undertaking a sanitary inspection.

Typical Problems Preventing Effective Sanitary Inspection When Practiced

· No standardised methodology

· Field interpretation of results varies between staff

· Data are difficult to quantify or compare due to subjectivity in interpretation and 'observational' style.

· No reporting structure to regional or national level

· No effort made to consolidate or analyse data at regional level in order to investigate general trends or common problems
