The learner will gain an understanding of water quality parameters and parametric values, legal requirements of drinking water treatment and customer expectations. The module also introduces "risk" and "barrier" approach to achieving safe drinking water and monitoring requirements. Also introduced in the module are loss and wastage of water during treatment. The learner will also carry out lab testing for key water quality parameters measured routinely at plants.


Learning Outcomes

On completion of this module the learner will/should be able to;


Define and describe water quality parameters, parametric values and methods of assessment and consumer expectations.


Describe disinfection processes, distinguish between drinking water treatments processes and identify DWTP plant performance, how determine performance, critical control points, safe and secure water.



Identify and describe the "risk" and "barrier" approach to achieving safe drinking water and the main contaminants of water and their sources.


Understand  Log Credit and Log Removal approach to Water Treatment, describe drinking water monitoring requirements and carry out lab testing.



Describe preventative measures and remediation works for loss/wastage of treated water

Teaching and Learning Strategies

This module will be delivered using blended learning techniques. This will include online lectures (via adobe connect or similar), workshops and site visits augmented by independent learning and directed learning. This approach is expected to address student-learning needs. A learning platform such as Moodle will be used to upload educational material (i.e. presentations and recordings of online lectures plus supplementary reading material) and as a means of assessment (e.g. quizzes, uploading assignments and journals). This blended approach (lectures and workshops) brings students together to facilitate group

Module Assessment Strategies

This module is 40% continuous assessment and 60% final exam.

  • Log Credit and Log Removal approach to Water Treatment.  
  • The testing of water for basic parameters including the understanding of the significance of guide levels and parametric values and consumer requirements.
  • Introduction to all common treatment processes and their designs for both ground and surface waters processes in treatment plants. Particular emphasis on disinfection.
  • Sources of drinking water contamination, micro-organisms and pollution control.
  • Raw water  - monitoring requirement characterisation , operation of DWTP link to RAW water quality.
  • Real time online monitoring and fault feed back on critical  plant  to assist measure plant performance.
  • DWTP plant performance, how determine performance, critical control points, safe and secure water.
  • How Critical Unit Process is controlled on continuous basis and measurement and tracking carried out on a continuous basis. 
  • Process Control and how it can be applied to the treatment of Drinking Water. 
  • Process Control Charts and their application in Drinking Water Treatment. Data records.
  • Essential monitoring records to be maintained for analysis. 
  • Understanding of how to detect when process is out of control and what action to take to ensure Multi Barrier Approach remains in place to protect human health and satisfy DWSP. 
  • Risk and Barrier approach to achieving safe drinking water.
  • Lab testing for key water parameters such, eg. Colour, Turbidity, Alum, Total & Free Chlorine, Fluoride, pH, Conductivity, Jar testing.
  • Water loss, and wastage during treatment.
