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
• Procedure 6: Identify critical control points
• Procedure 7: Establish operational limits Raw Water Transfer Storage

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
