Upon successful completion of this module the learner shall be able to define and interpret the scientific and engineering concepts as they relate to wastewater and water treatment, and sludge treatment and disposal.  They shall also be able to evaluate the characteristics and design of sustainable treatment systems that meet appropriate economic, environmental and regulatory requirements.  

Learning Outcomes

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


Define and interpret the scientific principles and engineering concepts as they relate to wastewater, raw water and sludge from a range of domestic, industrial and commercial sources


Formulate and evaluate the process options to control water pollution, to remove contaminants from wastewater, to provide clean drinking and industrial water for supply systems and render sludge suitable for treatment and disposal to the environment.


Design systems that provide for efficient removal of contaminants from raw water for the supply of drinking water, treatment of raw wastewater prior to discharge to water bodies, and water and wastewater sludge management within a sustainable framework.


Perform, observe and report critically on a range of laboratory experimental tests and process design software for raw and treated water, wastewater and sludge samples, observing and recording data and experimental evidence in teams, and recognise and advise on any limitations or shortcomings associated with the interpretation of laboratory and process design data.


Design, test and report on specific process design projects and field studies relating to water, wastewater or sludge treatment systems

Teaching and Learning Strategies

The teaching and learning strategy is based on the use of both direct verbal and visual instruction (theory lectures, presentations and practical and project briefings), and aural learning by giving instruction and guidance during laboratory project work, site visits, and assignments. 

Group interaction and enquiry-based learning is encouraged during project and laboratory work using group feedback to review progress and facilitate group discussion and collaboration.

The learning is also supplemented by independent learning with library, on-line and digital resources available for learners to research publications and knowledge for assignments, project work and to complement theory from lectures.

This strategy is accommodated by providing three hours per week of theory lectures and two hours per week of laboratory and project work classes.

Module Assessment Strategies

The module is assessed using a blended mix of final semester examination (70%) and laboratory practical,  project and site visit report work (30%).

Each learner must achieve a mark of at least 40% to pass the module and meet the learning outcomes.

Assessment of the examination and submitted project reports shall be summative in form. Formative assessment will also be used continuously during the laboratory, project and site visit report work to guide and provide feedback on progress to the learner.

Group work, where appropriate, is assessed by determining the individual contribution of each learner using group meetings, discussion and feedback. 

Repeat Assessments

Learners shall repeat only the failed elements. The learner must then achieve an overall mark of 40% to pass the module, including repeat assessments, which will be determined from the combination of assessment elements as per the assessment strategy.

2017-04-07 Water Science and Technology, Fourth Edition CRC Press
ISBN 9781351817851 ISBN-13 135181785X

Water has become one of the most important issues of our time intertwined with global warming and population expansion. The management of water supplies and the conservation of water resources remains one of the most challenging yet exciting issues of our time. Water and wastewater treatment technologies are constantly evolving creating an increasingly sustainable industry that is one of the world's largest and most interdisciplinary sectors, employing chemists, microbiologists, botanists, zoologists as well as engineers, computer specialists and a range of different management professionals. This accessible student textbook introduces the reader to the key concepts of water science and technology by explaining the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management. This fourth edition is extensively changed throughout, with new coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity. The text serves as a primer for both undergraduate and graduate students in either science or engineering who have an interested in freshwater biology/hydrobiology or environmental engineering. It is also useful as a unified transitional course for those who want to span the traditional areas of engineering, biology, chemistry, microbiology or business. Professionals and consultants will also find the book a useful reference.
