• Problem is acknowledged

• Much has already been done in South Africa to redress the problem

Not only a problem of developing countries

1970 – 2002 - 71 incidences recorded• Organisms responsible for events

Cryptosporidium, Giardia, E coli, Campylobacter,Shigella, Viruses

• Number of confirmed cases Varied from 10 – 1480

Fully integrated system

Key components of the WQSP

• Integrated water quality management system• Holistic in approach• Includes risk and hazard assessment• Identifies critical control points• Predefines operational limits• Establishes monitoring programme• Principle of multiple barriers• Proactive remedial actions• Clearly defines responsibilities

Programme outlineComprised four modules and 11

procedures–Module 1: Introduction into

water quality and water quality safety plans

–Module 2: Defining the WQSP

–Module 3: Setting up the WQSP

–Module 4: Maintaining the WQSP

Module 1 contents

• Discusses issues pertaining to water quality and the need for managing water quality

• Explains WQSP, where they come from and why this is considered a sound solution for managing water quality

• Trains learner to compile procedures using standard ISO 9001 principles

Module 1 outcomes

• Learners will:– Learn about issues pertaining to drinking

water quality– Understand what are the critical issues

needed to safeguard consumers– Get to grips with the logic functioning of

WQSP and how they can assist them in managing water quality

– Obtain the knowledge to use ISO 9001 procedure writing techniques

Module 2 contents

• Procedure 1: Establish what resources would be required to develop and sustain a WQSP.

• Procedure 2 Define corporate commitment to water quality – What is needed legally and : contractually

• Procedure 3: Define scope of WQSP• Procedure 4: Entails the compilation of flow

diagrams of the entire water supply chain.

Module 2 outcomes

• Learners will learn to:– Establish who is involved in managing Water

quality – Appoint a WQSP champion– Establish what is required from them with

regard to water quality – Conclude contents of WQSP– Construct flow diagrams of the water supply

chain– Understand the functioning of the water supply

chain

Module 3 contents

• Procedure 5: Conduct risk and hazard assessment

Module 3 outcomes

• Learners will learn to– Differentiate between risks and hazards– Conduct a risk and hazard assessment – Identify critical control points throughout

the water supply chain– Identify CCP where operational limits are

required– Set operational limits for required water

quality variable

Module 4 contents• Procedure 8: Establish monitoring

programme• Procedure 9: Verify drinking water

quality• Procedure 10: Establish corrective

actions• Procedure 11: Support programme

Module 4 outcomes• Learners will learn to:

– Develop a monitoring programme capable of verifying that operational limits are met

– Compile verification reports in respect of drinking water quality

– Develop proactive corrective procedures and protocols that would guide staff in correcting situations where operational or water quality limits are exceeded

– Identify required WQSP support
