Development report (2003)
• 240% higher in developing countries
compared to industrialized countries
• 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

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
• Procedure 6: Identify critical
control points
• Procedure 7: Establish
operational limits
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
Learner evaluation
On completion of 3 day WQSP
workshop learners need to complete
portfolio of evidence consisting of:
– Worksheets that needs completion in respect
of each procedure.
– Completed workbook tasks for each of the 11
procedures
